ABSTRACT
The purpose of the paper is to take a comprehensive look at Business Process
Reengineering (BPR), which is a popular term for the reoptimization of organizational
processes and structures after the implementation of new information technologies into
an organization. There is some evidence that changes in the use of information
technology (IT) in an organization may require major restructuring of the organization to
take full advantage of the technologies. This paper will attempt to demystify the myths
of BPR. It will examine the advantages and disadvantages of BPR in organizations. The
paper will also explore the various phases of the BPR process and the relationship
between BPR and Information Technology (IT). Information Technology should be
viewed as more than an automating tool but rather a fundamental way to reshape the way
business is done. The examination of IT will reveal the use of IT tools within the BPR
process which typically results in faster, better and cheaper solutions at each phase of the
BPR process. The primary methodology of the research will be through literature.

Business Process Reengineering: Introduction
Business Process Reengineering (BPR) is known by many names, such as core
process redesign, new industrial engineering or working smarter. All of them imply
the same concept that focuses on integrating both business process redesign and
deployment of information technologies (IT) to support the reengineering work. Thispaper will attempt to introduce some of the more important aspects of BPR and the
significance and role of information technology in BPR. In addition, the paper will
explore two questions: where does BPR comes from and what is involved in BPR interms of principals and assumptions.
What is BPR?
Business process reengineering ideas are based on the premise that every
organization needs a sense of direction. Without that direction in the form of strategicplans and business plans, the organization has no foundation upon which to build process
improvements.
BPR is a method of improving the operation and therefore the outputs oforganizations. Generally the topic of BPR involves discovering how business processes
currently operate, how to redesign these processes to eliminate the wasted or redundant
effort, improve efficiency, and how to implement the process changes in order to gaincompetitiveness.
The purpose of BPR is to find new ways to organize tasks, organize people andredesign information technology so that the processes support the organizations goals. It
means analyzing and altering the business processes of the organization as a whole.
For a thorough and effective reengineering project, organizations should first
meet certain conditions before starting such a project. Initially, the management shouldabandon all the rules and procedures that have been used up to that time. In addition they
should abandon other inadequate organizational and production principles. At this point,
the design of a renovated and redesigned organization should begin.
The Definition of BPR
BPR was first introduced in a research program at MIT (Massachusetts Institute
of Technology) in the early nineties. The term was used in the description of Davenport
and Short's 1990 research project. They found out that the implementation of moderninformation technology in organizations means not only automation of managerial and
production tasks but that it also has a direct effect on the quality of the work done.
Davenport (1993), one of the fathers of BPR describes business process redesign as:
...the analysis and design of workflows and processes within and between
organizations. Business activities should be viewed as more than a collection of

individual or even functional tasks; they should be broken down into processes
that can be designed for maximum effectiveness, in both manufacturing andservice environments.
It is argued by some researchers that there is no commonly agreed definition of
BPR. However, the bookReengineering the Corporation: A Manifesto for BusinessRevolutionby Hammer and Champy (1993) is widely referenced by most BPR
researchers and is regarded as one of the starting points of BPR. The following is their
definition of BPR:
[Reengineering is] the fundamental rethinking and radical redesign of business
processes. to achieve dramatic improvements in critical, contemporary measuresof performance, such as cost, quality, service and speed. (p. 32)
Dr. Michael Hammer is the primary originator and leading expert of the conceptof business reengineering and the founder of the reengineering movement. This point was
further discussed and developed by Hammer in his "Reengineering Work: DontAutomate, Obliterate", Harvard Business Review, 1990.
The Key Concepts
BPR seeks to break from current processes and to devise new ways of organizingtasks, organizing people and making use of IT systems so that the resulting processes will
better support the goals of the organization. This activity is done by identifying the
critical business processes, analyzing these processes and redesigning them for efficientimprovement and benefit. Vidgen (1994) defines the central key points of BPR as:
radical change and assumption challenge process and goal orientation
organizational restructuring
the exploitation of enabling technologies, particularly information technology
which means that by focusing on business objectives, processes are analyzed in the
organization, non-essential or redundant procedures are eliminated, and then IT is used to
redesign and streamline organizational.
BPR as Radical Change
BPR is a radical change rather than an incremental change. Davenport (1993)advocates radical change as:
Objectives of 5% or 10% improvement in all business processes each year mustgive way to efforts to achieve 50%, 100%, or even higher improvement levels in a
few key processes. Radical change is the only means of obtaining the order of
magnitude improvements necessary in todays global marketplace. Existing

approaches to meeting customer needs are so functionally based that incremental
change will never yield the requisite interdependence.
One reason the change in BPR is radical rather than incremental is to avoid being
trapped by the way things are currently done. Dr. Robinson (1994) of IBM UK highlights
rapid IT innovation and increasingly intensive global competition as two main reasonswhy organizations have had to consider the introduction of radical change. Revised
processes drive the shape of an organization. These radical changes are not limited to
inside the organization but can transcend to other organizations, which generate newviews for an organization.
Process-Orientation: From Structure to Process
Many current business processes with their functional structures were designed to
enable efficient management by separating processes into small tasks that could be
performed by less skilled workers with little responsibility. Under this structure, the
higher skilled and more trusted managers made the important decisions. Traditionalstructural approaches to a business reengineering generally follow this sequential order.
First, a business strategy is proposed, then the business structures and processes are
planned, and finally they are implemented with IT. In comparison, BPR is regarded asprocess-oriented which is trying to overcome some problems raised by hierarchical
structures. That means, BPR as a process-orientation changes the structural relationships
between management and employers into the interactive processes between them. BPRattempts to radically break the existing process structures and replace them with
innovative solutions.
BPR Process and Approach
Process redesign, often called BPR, takes a clean sheet approach to the process,
which is usually either broken, or so slow that it is no longer competitive in delivering thecompanys value to its customer. Inputs and outputs are defined, and checked to ensure
they align with customers present, and future, requirements. New technology, methods
and data flows are considered in relation to the process. A new process is designed fromscratch using the above. The change is planned and implemented to achieve minimum
disruption. Where a fundamental redesign of the entire process is not required, processimprovement can take different forms like analysis and improvement, continuous
improvement or simply attempts to gain more control.
The most common approach to process improvement is to take an
underperforming process, which is key to achieving the business objectives, and create a
systematic analysis to determine the most important areas for improvement. These arethen addressed on a project-by-project basis. A temporary process improvement team
that primarily consists of people within the process controls the analysis and
improvement. Continuous improvement is the ongoing management of the process after
it has been redesigned and streamlined. This is part of an overall culture change thatneeds to be clearly thought through and well directed from the top of the organization.

Davenport & Short (1990) define business process as "a set of logically relatedtasks performed to achieve a defined business outcome." A process is "a structured,
measured set of activities designed to produce a specified output for a particular customer
or market. It implies a strong emphasis on how work is done within an organization"
(Davenport 1993). In their view processes have two important characteristics:
a) They have customers (internal or external)
b) They cross-organizational boundaries
Processes are generally identified in terms of beginning and end points, interfaces,
and organization units involved, with special emphasis on customers. Examples ofprocesses include developing a new product, ordering goods from a supplier, creating a
marketing plan or processing and paying an insurance claim.
According to Davenport & Short (1990), processes may be defined based on three
dimensions:
a) Entities: Processes take place between organizational entities. They could beinterorganizational, interfunctional or interpersonal.
b) Objects: Processes result in manipulation of objects. These objects could be
physical or informational.c) Activities: Processes could involve two types of activities: managerial and
operational.
Myths about BPR
The concept of BPR has been around since about 1990, however it is widely
misunderstood and has been equated to downsizing, client/server computing and several
other management techniques of the past several years. Based on interviews andconversations with more than 200 companies, and 35 reengineering initiatives, Davenport
& Stoddard (1994) identify several reengineering myths.
The Myth of Reengineering Novelty: Reengineering, although based on familiarconcepts, introduces new concepts that are combined in a new format. These key
components have never been together before.
The Myth of the Clean Slate: Regardless of Hammer's (1990) sentiment: "Don't
automate, obliterate!" clean slate change is rarely found in practice. Or, as Davenport and
Stoddard (1994) state: A "blank sheet of paper" used in design usually requires a "blankcheck" for implementation. Therefore, a more affordable approach for most companies is
to use Clean Slate Design, which involves a detailed vision for a process without concern
for the existing environment. However, the implementation is done over several phasedprojects. Some opponents of BPR say that despite the delivery of radical design, it does
not guarantee a revolutionary approach to change. Moreover, a revolutionary change
process might not be feasible given the risk and cost of revolutionary tactics.

The Myth of Information Systems Leadership: Information Systems (IS) is generallyviewed as a partner within a cross-functional team that is generally headed by a non-IS
project leader and a non-IS businessperson who has better control over the processes that
are being redesigned. The distinction between IT and IS begins with the idea that IT
offers strategic relevance. Moreover, IT has an impact on BPR projects that can improvethe quality of an organizations information systems management.
The Myth of Reengineering vs. Quality: Most companies have approaches toorganizational change including reengineering, continuous improvement, incremental
approaches, and restructuring techniques.
The Myth of Top-Down Design: The implementation and execution of the redesigned
processes depends upon those who do the work. Therefore, the participation and
acceptance and ownership should begin at the grass roots level and is essential forsuccessful BPR.
The Myth of Reengineering vs. Transformation: BPR is a process that contributes to
organizational transformation, however it is not the same as transformation.Organizational transformation is defined as, "Profound, fundamental changes in thought
and actions, which create an irreversible discontinuity in the experience of a system"
(Adams 1984). Organizational transformation is generally about the emergence of a newbelief system and necessarily involves reframing, which is a discontinuous change in the
organization's or group's shared meaning or culture. It also involves broad changes in
other organizational dimensions besides the work processes.
BPR Success/Failure Factors
In 1996 Davenport published an article entitled Why Reengineering Failed: The
Fad that Forgot People in which he reports:
To most business people in the United States, reengineering has become a word
that stands for restructuring, lay-offs, and too often, failed change
programs..companies that embraced [reengineering] as the silver bullet are nowlooking for ways to re-build the organizations torn fabric. (Davenport, 1996)
Also in 1998 it was reported that only around 30% of BPR projects were regarded
as a success (Galliers, 1998). BPR was not reaching its potential and there are variousreasons for its limited success. Some explanations of such high rates of failure for BPR
projects have been discussed in BPR literature. For example, employees resistance tochange as they consider BPR as threats to their jobs. In addition, BPR approaches lackdetailed guidance and support for the actual implementation of reengineering. Many
publications describe the situation before and after BPR but do not discuss the path to
reach the final situation. Some experts explain that one reaction to this failure was toretain faith in IT as a dominant support and just adapt business activities to IT.

Following the publication of the fundamental concepts of BPR by Hammer
(1990) and Davenport and Short (1990), many organizations have reported dramaticbenefits gained from the successful implementation of BPR. Companies like Ford Motor
Co., CIGNA, and Wal-Mart are all recognized as having successfully implemented BPR.
However, despite the significant growth of the BPR concept, not all organizations
embarking on BPR projects achieve their intended result. Hammer and Champy (1993)estimate that as many as 70 percent do not achieve the dramatic results they desire.
Having BPR repeatedly at the top of the list of management issues in annual surveys of
critical information systems shows executives' failure to either implement properly oracquire the benefits of BPR. These results make the issue of BPR implementation very
important. BPR has great potential for increasing productivity through reduced process
time and cost, improved quality, and greater customer satisfaction, but it often requires afundamental organizational change. As a result, the implementation process is complex,
and needs to be checked against several success/failure factors to ensure successful
implementation, as well as to avoid implementation pitfalls.
There are both soft and hard factors that cause success and failure of BPR efforts.The factors listed below are based on various articles and empirical research on BPR
implementation. These dimensions are:
change management
management competency and support
organizational structure
project planning and management
IT infrastructure
Factors relating to change management systems and culture
Factors relating to change management systems and culture are important to the
success of BPR initiatives. Change management, which involves all human- and social-
related changes needed by management to facilitate the acceptance of newly designed
processes and structures into working practice and to deal effectively with resistance, isconsidered by many researchers to be a crucial component of any BPR effort.
Effective communication is considered a major key to successful BPR-related
change efforts. Communication is needed throughout the change process at all
levels and for all audiences, even with those not involved directly in the reengineeringproject. Effective communication between stakeholders inside and outside the
organization is necessary to market a BPR program and to ensure patience andunderstanding of the structural and cultural changes needed as well as the organization'scompetitive position. Communication should be open, honest, and clear, especially
when discussing sensitive issues related to change such as personnel reductions.
As BPR results in decisions being pushed down to lower levels, empowermentof both individuals and teams becomes a critical factor for successful BPR efforts. Since
it establishes a culture in which staff at all levels feel more responsible and accountable

and it promotes self-management and a collaborative teamwork culture. Empowerment
means that staff is given the chance to participate in redesign processes. Whenempowered, employees are able set their goals and monitor their own performance as
well as identify and solve problems that affect their work thereby supporting the BPR
efforts.
In reengineering, there is the human involvement element in which all peoplemust be openly and actively involved and should be consulted at all stages of the process
and its leaders. This includes line managers, process owners and those involved in IS and
human resources. The idea of experimentation is an essential part of a successfully re-
engineered organization and, therefore, people involved or affected by BPR must beprepared to endure errors and mistakes while reengineering is taking place.
Factors for Management Competency
Sound management processes ensure that BPR efforts will be implemented in the
most effective manner. The most noticeable managerial practices that directly influence
the success of BPR implementation are top management support and commitment,championship and sponsorship, and effective management of risks.
Commitment and leadership in the upper echelons of management are often citedas the most important factors of a successful BPR project. Leadership has to be effective
and creative in thinking and understanding (Hammer and Champy, 1993) in order to
provide a clear vision of the future. This vision must be clearly communicated to a widerange of employees who then become involved and motivated rather than directly guided.
Commitment to and support for the change must constantly be reinforced from senior
management throughout a BPR project. Sufficient authority and knowledge, and proper
communication with all parts in the change process, are important in dealing withorganizational resistance during BPR implementation (Hammer and Champy, 1993).
Barriers such as political, economic, and organizational risks are all associatedwith BPR-related change. And champions of the change play a major role in overcoming
these barriers and increasing the chance of successful BPR implementation. The
champions must be able to persuade top management of the need to change and tocontinually push the change efforts throughout the organization.
BPR implementation involves radical change to several systems in the
organization. Risks associated with acceptance of changes in the organizationalstructure, deploying emerging technologies with little familiarity, large investment in
new resources needed for the new processes, loss of personnel, and loss ofearnings (Towers, 1994; Clemons, 1995) are some examples of the many risksthat an organization may take when implementing BPR. Therefore, continuous
risk assessment is needed throughout the implementation process to deal with any risk at
its initial stage and to ensure the success of the reengineering efforts. Anticipating andplanning for risk handling is important for dealing effectively with any risk when it first
occurs.

Factors relating to Organizational Structure
As BPR creates new processes that define jobs and responsibilities across the
existing organizational functions (Davenport and Short, 1990), there is a clear need to
create a new organizational structure which determines how BPR teams are going to
look, how human resources are integrated, and how the new jobs and responsibilities aregoing to be formulated. An adequate job integration of organizational human resources
infrastructure is important to a BPR project's success. When individuals within a process
perform a series of tasks efficiently, product quality, processing time, and cost are allgoing to improve. However, the move to integrate human resources necessitates a careful
consideration of all related organizational changes. Effective BPR cross-functional teams
are a critical component of successful BPR implementation.
Team members should be experienced in variety of techniques. Teams should be
made up of people from both inside and outside the organization (Hammer and Champy,1993). The determinants of an effective BPR team are as follows: competency of team
members, their credibility within the organization and their creativity, teamempowerment, motivation, effective team leadership, proper organization of the team,
complementary skills among team members and adequate size. As BPR results in amajor structural change in the form of new jobs and responsibilities, it becomes necessary
for successful implementation to have formal and clear descriptions of all jobs and
responsibilities that the new designed processes bring along with them.
Factors related to BPR Project Management
Successful BPR implementation is highly dependent on an effective BPR
Program management, which includes strategic alignment, effective planning and projectmanagement techniques, identification of performance, adequate resources, effective use
of consultants, building a process vision integrating BPR with other improvement
techniques. Proper planning for the BPR project with an adequate time frame are keyfactors in delivering a successful BPR project on time. Effective use of project
management techniques and managing people-related issues have also a crucial role in
smoothing the flow of the process redesign stages. Measurement of project progress
should also be maintained continually throughout a BPR project.
Factors related to IT infrastructure
Building an effective IT infrastructure is a vital factor in successful BPR
implementation. An adequate understanding of technologies for redesigning businessprocesses is necessary for proper selection of IT platforms. Effective overall system
architecture, flexible IT infrastructure and proper installation of IT components all
contribute to building an effective IT infrastructure for business processes. The ITinfrastructure and BPR are interdependent in the sense that deciding the information
requirements for the new business processes determines the IT infrastructure. In
addition, recognition of IT capabilities provides alternatives for BPR. Building aresponsive IT infrastructure is highly dependent on an appropriate determination of

business process information needs . This, in turn, is determined by the types of activities
within a business process, and the sequencing and reliance on other organizationalprocesses.
An effective IT infrastructure follows a top-down approach, beginning with
business strategy and IS strategy and passing through designs of data, systems andcomputer architecture. Linkages between the IT infrastructure components are important
for ensuring integrity and consistency among the IT infrastructure components. IT
standards also have a major role in reconciling various infrastructure components toprovide shared IT services that are of a certain degree of effectiveness to support business
process applications. The IT infrastructure shared services and the human IT
infrastructure components, in terms of their responsibilities and their expertise, are bothvital to the process of the IT infrastructure composition.
Selecting an IT Application
One main objective of BPR is to use IT to support radical change. Some authorsview IT as the central implementation vehicle of BPR. However BPR has not really
worked as its proponents expected. Davenport and Short (1990) attribute this problem toa lack of understanding of the deeper issues of IT. They claim that IT has traditionally
been used to increase the speed of work but not to transform it and BPR is about using IT
to do things differently. Therefore, IT plays an important role in BPR. Properlyimplementing IT can improve the competitive position of organizations. But
inappropriately implementing IT may create barriers to responding to the rapidly
changing business environment. Further, simply picking IT packages cannot achievesuccessful BPR if it is simply used to speed up the process rather than reengineer it. As
Davenport (1993) contends:
... information and IT are rarely sufficient to bring about the process change; most
process innovations are enabled by a combination of IT, information andorganizational/human resource changes.
IT can continuously reflect and reinforce bureaucratic and functional structures or
IT can help to create a leaner, flatter and more responsive organization. For example, ITtools that are designed for functional hierarchies are primarily designed to support
incremental improvements and cannot achieve the radical change in BPR projects.

Figure 2. BPR Strategies (Light, 2000)
While information systems provide fast processing and response, they often fail toprovide the flexibility for human communication, which can lead to serious
consequences. This means IT may sometimes have a negative impact by merely
automating the existing processes. However, it could also have a positive impact if it is
deployed correctly in conjunction with the organizations goals. IT is the enabler toreengineer processes and is an important driving force for business transformation.
Relationship between IS and Organizations
There are many techniques for systems analysis and modeling, operations
research, information systems (IS), and human resource management to name a few.However, system development techniques play an important role in BPR that helps make
sense of the current systems. In addition, analyzing the potential benefits of the
redesigned systems can help identify those information systems that will function as thegreatest supporter for the radically redesigned processes.
Information systems are widely used in business and identify those systemsinserted into organizations to support data processing and the decision making process.
In general, information systems are regarded as a kind of structure, which reflects the
activities of the organization, and software system is a part of it. From this viewpoint,
information systems represent abstractions of social systems. The following figurerepresents the relationship between the world and a software system, with the software
system becoming an abstraction of the world. The following figure links the world and
software.

Figure 3. Linking the World and Software (Cook, 1994)
The figure suggests that software is a concept model, which partially duplicates
and abstracts the behavior of things in the world. However they point out one potentialproblem, which is that software cannot totally model the real world. This is because the
world is unpredictable but software is as predictable as its behavior is preconceived. Also
as software is a part of the world, it is impossible to design software on the assumption
that its existence will not change the world. However, traditional system development isconcerned with software systems only and assumes that software
will not affect the basic structure of the organizations. What is not taken into account is
that new software solutions can provide new opportunities for business changes. That is,any designed information system is unlikely to be perfect for the purpose for which it was
designed, and this is why today many organizations have faced legacy systemproblems
because their computer systems cannot be changed to serve the changing circumstancesof the organization.
For BPR, it is likely that providing IT to support a process may change the
process itself, which leads to additional degrees of support. Therefore, if IT is accepted inorganizations then a change to the organizational environment will be necessary. This
suggests that the process of reengineering is dynamicand will inevitably lead to further
iterations in which the reengineered processes need to be reevaluated and redesigned. Theconclusion is that business reengineering and software development cannot be
independent of each other. The redesign of business processes will decide the
requirements of a software system, whereas the introduction of software systems willinevitably affect the way the business is currently running. The development of software
-
7/29/2019 Text and cases

13
systems and the process of BPR are considered interdependent. The evolution of
software systems should be based on two facts: first, the organizational software shouldbe dynamic, and second, the outcome of the software system operation is somewhat
unpredictable. That is, a software system cannot move from steady state to steady state. It
must constantly evolve to meet new goals, and to facilitate the development of
organizational processes.
It is obvious that the introduction of software systems will change peoples
perceptions as well as their behavior and, when such systems are implemented in anetworked structure, this has far-reaching impact on the behavior of organizations.
Peoples perceptions of organizations and the relationships between IT and organizations
may be different depending on which model is used. The three dimensions of anorganization include machines, organisms and processes. Each represents three waves of
organization theory. The first wave, to perceive an organization as a machine,suggests
that IT can be seen as a controllable resource, which is not part of the organization and isused to achieve specific objectives. The introduction of IT does not affect the
organizational structure but does affect the relationship between management andworkers. The second wave, regards IT as more integrated and less controllable. IT is an
element of an organization that has the potential to be an unpredictable resource.Typically, the workers have more ownership of the technology than management. The
third wave perceives an organization as a processand IT as a behavioral phenomenon.
Conventional system development methods consider an organization as amachine, whose behavior is merely determined by the behavior of individuals within the
organization. Systems development tends to concentrate only on the physical parts of IT
because it is hard to cope with the abstract things such as the perception and theinteraction of human beings. Unfortunately, these methods are not great for the analysis
of BPR because they only reflect the situations before and after the implementation of the
systems, but do not emphasize the change of peoples behavior once affected by IT.There is also a similar problem appearing in BPR, because it is common that many BPRmethodologies try to reduce the dynamic levels of business processes to predictable
management techniques. Methodologies focusing on static definitions of data, role and
processes to reflect organizational structures tend to remain less flexible for long periods.However these static methodologies cannot define dynamic processes because people
operate in dynamic manner and are prone to error causing a need for flexible systems.
From a systems viewpoint, an organization has more meaning as a whole than justas a sum of its parts. The characteristics of an organization cannot identify the
components of an organization. Today the greatest resource in organizations is the skill
and knowledge of people. Individual knowledge and technology does not only belong tothe people, but is also a part of the organization. Therefore, the behavior of organizationscan be regarded as a pattern of interactions between people. After the introduction of
software systems into organizations, the behavior can be understood as a pattern of
interactions between people, between people and software systems, and between thesoftware applications. The systems approach analyzes the impact upon organizations.
For this, the systems approach can be used to analyze the impact of IT upon
organizations, because the nature of IT can only be assessed in terms of its total impact.

An organization is a creation of the perceptions of the people involved within it. Any
change in the organization will have an impact on peoples perception of theorganization. When analyzing business processes, we find that people interact with each
other within the process and are also influenced by that process. How people will react in
organizations depends on how they perceive a particular action, and their perception is
important in the process of interaction. Today IT plays an important role in organizationsbecause people use their systems to interact with others and the environment. Therefore
any changes in IT may cause changes in organizational structure. Harrington (1991)
suggests that systems methodology is a successful way to analyze the impact of ITorganizations because it not only reflects the way people tend to interact, and therefore
capturing the essence of how people organize, it also shows the changes that occur as a
whole rather than just a part of the organization.
BPR and Information Technology
There is a relationship between BPR and information technology (IT). Hammer
(1990) considers it to be the key implementation of BPR. He says the use of IT is tochallenge the assumptions inherent in the work processes that have existed since before
the advent of modern computer and communications technology. He argues that at theheart of reengineering is the idea of discontinuous thinking. Discontinuous thinking is a
way to recognize and break away from the outdated rules and fundamental assumptions
that underlie operations. Usually, these rules are based on assumptions about technology,people, and organizational goals that no longer exist. Hammer (1990) suggests the
following principles of reengineering:
a) Organize around outcomes, not tasks
b) Have those who use the output of the process perform the processc) interleave information processing work into the real work that produces the
information
d) Treat geographically dispersed resources as though they were centralizede) Link parallel activities instead of integrating their results
f) Put the decision point where the work is performed, and build control into the
process
g) Capture information once and at the source
Davenport & Short (1990) argue that BPR requires taking a broader view of both
IT and business activity, and of the relationships between them. IT should be viewed asmore than an automating or mechanizing force but rather as a way to fundamentally
reshape the way business is done. Many researchers and practitioners have increasingly
considered factors related to IT infrastructure as a vital component of successful BPRefforts. Effective alignment of IT infrastructure and BPR strategy, building an effective
IT infrastructure, adequate IT infrastructure investment decision, adequate measurement
of IT infrastructure effectiveness, proper IS integration, effective reengineering of legacyIS, increasing IT function competency, and effective use of software tools are a few of

of IT infrastructure and BPR strategy are needed to ensure the success of the BPR
initiative.
IT can best enhance an organizations position by supporting a business-thrust
strategy (McDonald, 1993). The business strategy should be clear and detailed. Top
management should act as a strategy formulator who provides commitment for the wholeprocess of redesign, while the IS manager should be responsible for designing and
implementing the IS strategy. The strategy describes the role of IT in leveraging changes
to business processes and infrastructures. IT strategic alignment is approached throughthe process of integration between business strategy and IT strategy, as well as between
IT infrastructure and organizational infrastructure. The degree of alignment between the
BPR strategy and the IT infrastructure strategy is indicated by including the identificationof information resource needs in the BPR strategy, deriving the IT infrastructure strategy
from the business strategy, examining the IT infrastructure strategy against the BPR
strategy, the active involvement of management in the process of IT infrastructureplanning and IT managers in business planning, and by the degree of synchronization in
formulating the two strategies. The following figure shows the multidimensional natureof BPR.
Figure 4. Multidimensional View of BPR (Light, 2000)
Business activities should be viewed as more than a collection of individual or
even functional tasks. They should be viewed as a way to achieve maximum
effectiveness. IT and BPR have recursive relationships. IT capabilities should support
business processes and business processes should be implemented in terms of thecapabilities IT can provide. Davenport & Short (1990) refer to this broadened, recursive
view of IT and BPR as the new industrial engineering. Business processes represent a

new approach to coordination across an organization. IT's promise is to be the most
powerful tool for reducing the costs of coordination (Davenport & Short 1990).
The way related functions participate in a process can be differentiated along two
dimensions: degree of mediation and degree of collaboration. They define the Degree of
Mediation of the process as the extent of sequential flow of input and output amongparticipating functions. They define the Degree of Collaboration of the process is the
extent of information exchange and mutual adjustment among functions when
participating in the same process. In this framework, information technology is critical inreducing the Degree of Mediation and enhancing the Degree of Collaboration. Also,
innovative uses of IT would inevitably lead many firms to develop new structures,
enabling them to coordinate their activities in ways that were not possible before. Suchstructures may raise the organization's capabilities and responsiveness, leading to
potential strategic advantages.
Although, BPR has its roots in IT management, it is primarily a business initiative
that has broad consequences in terms of satisfying the needs of customers and the firm'sother constituents (Davenport & Stoddard 1994). The IS group may need to play a
behind-the-scenes advocacy role, convincing senior management of the power offered byIT and process redesign. It would also need to incorporate the skills of process
measurement, analysis, and redesign.
Davenport and Short (1990) prescribe a five-step approach to BPR:
Develop the Business Vision and Process Objectives: BPR is driven by a businessvision, which implies specific business objectives such as Cost Reduction, Time
Reduction or Output Quality improvement.
Identify the Processes to be Redesigned: Most firms use anapproach, which focuses on
the most important processes, or those that conflict most with the business vision. Afewer number of firms use the exhaustive approach that attempts to identify all the
processes within an organization and then prioritize them in order of redesign urgency.
Understand and Measure the Existing Processes: Important to avoid the repetition ofold mistakes and for providing a baseline for future improvements.
Identify IT Levers: Awareness of IT capabilities can and should influence processdesign.
Design and Build a Prototype of the New Process: The actual design should not beviewed as the end of the BPR process. In contrast, it should be viewed as a prototype,
with successive iterations. The metaphor of prototype aligns the BPR approach with
quick delivery of results, and the involvement and satisfaction of customers.
According to Malhotra (1998), 70% of the BPR projects fail. He states the biggest
obstacles that reengineering faces are:

Lack of sustained management commitment and leadership.
Unrealistic scope and expectations.
Resistance to change.
Based on the BPR consultants' interviews, Bashein et al. (1994) outline thepositive preconditions for BPR success as: Senior Management Commitment and
Sponsorship; Realistic Expectations; Empowered and Collaborative Workers; Strategic
Context of Growth and Expansion; Shared Vision; Sound Management Practices;Appropriate People Participating Full-Time and Sufficient Budget. They also identify
negative preconditions related to BPR as: The Wrong Sponsor; A "Do It to Me" Attitude;
Cost-Cutting Focus; and Narrow Technical Focus. The negative preconditions relating tothe Organization include: Unsound Financial Condition; Too Many Projects Under Way;
Fear and Lack of Optimism; and, Animosity Toward and By IS and HR Specialists. To
turn around negative conditions, organizations should: Do Something Smaller First (pilotproject); Conduct Personal Transformation (change of mindset); and Get IS and HR
Involved.
King (1994) views the primary reason for BPR failure as overemphasis on thetactical aspects and the strategic dimensions being compromised. He notes that most
failures of reengineering are attributable to the process being viewed and applied at a
tactical, rather than strategic, levels. He discusses that there are important strategicdimensions to BPR, notably, Developing and Prioritizing Objectives; Defining the
Process Structure and Assumptions; Identifying Trade-Offs Between Processes;
Identifying New Product and Market Opportunities; Coordinating the ReengineeringEffort; and, Developing a Human Resources Strategy. He concludes that the ultimate
success of BPR depends on the people who do it and on how well they can be motivated
to be creative and to apply their detailed knowledge to the redesign of business processes(Davenport & Stoddard 1994, Markus et al. 1994).
Over the last few years, the reengineering concept has evolved from a "radical
change" to account for the contextual realism (Caron et. al 1994, Earl 1994), and to
reconcile with more incremental process change methods such as Total Quality
Management (TQM), towards a broader, yet more comprehensive process managementconcept (Davenport 1995).
Kettinger & Grover (1995) outline some propositions to guide future questionsinto the phenomenon of BPR. Their propositions center around the concepts of
knowledge management, employee empowerment, adoption of new IT's, and a sharedvision. Earl et al. (1995) have proposed a "process alignment model" that consists of fouremphases: process, strategy, IS, and change management and control and used it to
develop more BPR strategies. Malhotra (1998) has developed the key emphasis on these
issues based primarily on an integrated view of recent literature from organization theory,
organization control, strategy, and IS. King (1994) believes that although the currentinterest in BPR may end, process reengineering, in some form or another would endure.

The Future: BPR and ERP Systems
According to Light (2000), organizations are continuing to implement business
process change projects and one of the most important factors of the BPR concept
throughout the nineteen nineties has been the wide scale adoption of Enterprise Resource
Planning (ERP) systems. It is important to examine the link between these two areas.ERP systems are process oriented and highly integrated standard software systems, which
are used to automate core corporate activities such as, finance, logistics and human
resources.
The ERP applications market has grown enormously over the past several years.
Interestingly, Light (2000) mentions that the key reasons for the adoption of ERP systemsare closely tied to those for the evolution of BPR - the need to deal with legacy systems
in a complex and dynamic business environment. Companies are now looking to improve
the management of global operations and employ innovative supply chain basedcompetitive strategies such as the formation of new types of industrial structures.
However, many existing systems have become so difficult and costly to maintain,inflexible and misaligned with a global business strategy that organizations have taken a
clean slate approach towards their IT and have implemented ERP systems. Managers ofERP projects have suggested to Light (2000) that ERP is the new BPR. The reason for
this is because a key aspect of any ERP project is the need for most organizations to
undertake some form of BPR exercise. ERP systems are process oriented and, due to theirhighly interconnected nature, require organizations that implement these types of system
to adopt a process-oriented philosophy. Therefore, if an organization has not undergone
an organization wide reengineering exercise, they will have to do so. Even if there areelements of a process orientation within an organization, it is likely that a certain level of
reengineering will occur. This can have a considerable impact on competitive advantage.
Conclusion
Dramatic changes in the business environment throughout the nineteen eighties
forced organizations to examine outdated modes of work and develop new focused
strategies based on new business models. Many business management concepts emerged
but BPR has probably been the most influential. BPR emerged as a concept gearedtowards a clean slate, radial approach. However, the original ideas did not take into
account the situations in organizations where factors such as the evolution of the ways of
work, organizational cultures and IT infrastructures had become significantly linked withorganizations. A variety of methodologies, tools and techniques for BPR projects have
developed out of implementation failures. As a result, the concept of BPR has survived
and has been broadened to become more commonly associated with multidimensionalprocess change efforts. Reengineering is not just a matter of fundamental and radical
improvements in performance, but is also an approach to analyzing and transforming the
nature of businesses and industries.
