The Information Architecture• The world isn’t run by weapons anymore…It is run
by small bits of data…0’s and 1’s….• It’s not the one who has got the most bullets but
one who controls the information…• What we SEE…What we HEAR…What we
THINK…..
IT”S ALL ABOUT INFORMATION.
INFORMATION

Information
• More and more work depends upon effective use of Information
• Novel ways of accessing information are seen in offices, home, society, etc.
• More specialized, complex, more perplexing …
• Thus, design and efficient communication are more challenging than ever, requiring great deal of time, practice and knowledge

Notion of Design
• Separation of thinking and doing• Separation of manual and
intellectual work• Separation of conceptual part of
work from the labor process• Design-build process is more
specialized• Can be clearly seen in building-
architects and builders

Communication in ICT
• Human Society formed with oral speech• Oral speech is through specialized
adaptation of mind and body• Written culture 6000 years old• Brain power has played a significant
role• Creating, communicating, storing and
retrieving information is the challenge, which is as old as civilization itself
• Only the means by which we do have changed

Key Challenge: Towards a New Discipline
• Our ability to create information has outpaced our ability to search, organize and publish it
• Information management – at individual, organizational and societal level has turned out to be a key challenge

Theses of Information Architecture
• People need information.• More importantly, people need
the right information at the right time.
INFORMATION

What are some of the key benefits of an IT
Architecture?• It will help to insure interoperability inside
and outside ITB and the Department. • It's a way to inform developers of Department
directions. • It will help in making planning, development
and purchase decisions. • It will be useful in aligning information
technology providers for the Department. • It is a way to communicate direction (and
changes) both inside and outside ITB. • It will reduce the maintenance and support
requirements. • It will help in planning migration to new
technologies.

I am Frustrated
• Sense of frustration that business executives are experiencing in many organizations:
• "The automated systems my people want and need take too long to put into operation, and the backlog of requests just keeps growing."
• "We're spending millions on computers but nobody can show me how this system project supports corporate goals."

What is needed ?
• Way of planning our information systems to avoid these kinds of problems.
• The most promising approach: an Information Architecture to guide systems planning effort

What is IA
• An architecture is a high level or general view of something that conveys an overall understanding of its various components and how those components inter-relate.
• For example, examine the architecture of a house, we would see where the bedrooms were located relative to the kitchen-living-dining rooms.
• We tend to classify our homes based on the commonality of their architecture: bungalow, back-split, two-story, etc.

What is an IA?
• An information architecture is a high level or general view of an organization's information-related components that conveys an overall understanding of each component and an understanding of how these components relate to each other
INFORMATION

POWER
Internet and IA
• The Internet has changed how we live with information.
• It has made ubiquitous the once rare entity: the shared information environment
INFORMATION
IS
POWER
IA: Human Factor
• Shaping information to be relevant and timely requires specialized human work.
• Doing so for a globally shared environment that is itself made of information is a relatively new kind of specialized human work.
INFORMATION
IS
POWER
IA: Structuring of Raw Information
• This work is an act of architecture: the structuring of raw information into shared information environments with useful, navigable form that resists entropy and reduces confusion.
INFORMATION
IS
POWER
IA: Designs Structures of Information
• This is a new kind of architecture that designs structures of information rather than of bricks, wood, plastic and stone
INFORMATION
IS
POWER
IA: Information Homes
• People live and work in these structures, just as they live and work in their homes, offices, factories and malls.
• These places are not virtual: they are as real as our own minds.
INFORMATION
IS
POWER
Information Homes
• Many people spend most of their waking hours in these spaces.
• As the numbers of physical workers decline and knowledge workers increase, more and more people will live, work, share, collaborate, learn and play in these environments for more and more of their lives.
INFORMATION
IS
POWER
Information Mass
• There is already too much information for us to comprehend easily.
• Each day there will only be more of it, not less. Inexorably, information drowns in its own mass.
• It needs to breathe, and the air it needs is relevance.
INFORMATION

POWER
Towards IA
• Information has more than physical presence– Meaning– Imagery– Aesthetics– Value– Emotion– Shape
INFORMATION
IS
POWER
Towards IA
• Data is stored – Information is experienced– And experiences have human
consequences– We are shaping the experiences of
millions– How does content impact action– Whither IA?

Goals of Information Architecture
• One goal of information architecture is to shape information into an environment that allows users to create, manage and share its very substance in a framework that provides semantic relevance.
INFORMATION
IS
POWER
• Another goal of information architecture is to shape the environment to enable users to better communicate, collaborate and experience one another
INFORMATION
IS
POWER
• The latter goal is more fundamental than the former: information exists only in communities of meaning.
• Without other people, information no longer has context, and no longer informs. It becomes mere data, less than dust.
INFORMATION
IS
POWER
IA: Purpose
• The purpose of an information architecture is to ensure that everyone concerned, business people and systems staff alike, have a common understanding (or mental model) of the organization
INFORMATION
IS
POWER
• Therefore, information architecture is about people first, and technology second.
INFORMATION
IS
POWER
People needs
• All people have a right to know where they are and where they are going and how to get what they need.
• People naturally seek places that provide these essential needs.
• Any environment that ignores this natural law will attract and retain fewer people.
INFORMATION
IS
POWER
Interface Design
• The interface is a window to information. Even the best interface is only as good as the shape of the information behind it.
• The converse is also true: even the most comprehensively shaped information is only as useful as its interface.
• For this reason, interface design and information architecture are mutually dependent.
INFORMATION
IS
POWER
Immediate Access
• The Internet has changed our paradigm for more than just technology.
• We now expect all information environments to be as accessible, as immediate, and as total.
INFORMATION
IS
POWER
IA
• Just because information architecture happens mostly on the Internet today, it doesn't mean that will be the case tomorrow.
INFORMATION
IS
POWER
Tools
•Information architecture accomplishes its task with whatever tools necessary
INFORMATION
IS
POWER
IA Flavor
• These tools are being fashioned by many people, including information scientists, artists, librarians, designers, anthropologists, architects, writers, engineers, programmers & philosophers.
• They all bring different perspectives, and they all add flavor to the stew. They are all necessary.
INFORMATION
IS
POWER
Tools
• These tools come in many forms and methods, including:– Controlled vocabularies– Mental modeling– Brainstorming– Ethnography– Thesauri– Human-computer interaction, and others.
• Some tools are very old, and some are very new. Most are still waiting to be invented.
INFORMATION

POWER
IA: Practice
• Information architecture acknowledges that this practice is bigger than any single methodology, tool or perspective.

What Does An Information Architecture Contain?
• The information architecture contains information about a number of things of interest to the business. In its early stages of development, it contains information about:
• the current or planned organization structure,
INFORMATION
IS
POWER
What Does An Information Architecture Contain?
• the goals of the organization, • the business functions that
must be carried on to achieve the goals, and
• the major categories of things (subjects) the organization needs information about in order to perform the functions.
INFORMATION
IS
POWER
Benefits Of An Information Architecture?
• Better management communication.
• The architecture contains:– Business terms (not technical jargon)– All terms having common definitions
that were arrived at through consensus from all parts of the organization.
• When systems do get built, the systems staff will have a solid enterprise-wide foundation on which to base their efforts
INFORMATION
IS
POWER
Benefits Of An Information Architecture?
• Different parts of the business will start to communicate more effectively with other parts of the business.
• Basis for sequencing systems development projects in sensible ways.
INFORMATION

POWER
Benefits Of An Information
Architecture• Basis for sequencing systems
development projects in ways that make sense.
• We know which pieces create and maintain data needed for other pieces.
• We have a basis for building the data creation/maintenance pieces first.
• When business priorities dictate a different sequence, we can determine the full implications of such an approach in advance.
INFORMATION

POWER
Benefits Of An Information
Architecture• have the information we need for
more clearly defining the scope of our systems projects.
• Know in advance which business processes and which data components will be included in each project.
• We can have confidence that there will be no major hidden surprises as we go through the development process
INFORMATION
IS
POWER
Benefits Of An Information
Architecture• We have a basis for identifying all
of the stakeholders in any development effort.
• We will know in advance who ought to be involved in requirements definition and testing.
• We can plan for their participation and develop a higher quality more robust system as a result.
INFORMATION
IS
POWER
Benefits Of An Information Architecture
• we have the opportunity to identify common systems that can be used by a variety of people throughout the organization.
• Frequently there are business processes that are performed in several organization units, with each being done in a slightly different way.
• If a common system is developed to support this activity, the organization benefits in two ways: – There is improved consistency across the
organization– There is reduced cost since only one
system is built and maintained rather than several.

Conclusions
• IA is a rapidly emerging field concerned with the art and science of applying many approaches to the design of IS
• Several disciplines have to merge to architect the right systems
• Inf. Architect to develop Information structures usable at multiple levels of interaction among humans, machine and environment
INFORMATION

Conclusions• Information architecture is first an
act, then a practice, then a discipline.
• Sharing the practice grows the discipline, and makes it stronger.
