    Models and Standards

    ISO 17025 is an international standard that specifies the general requirements for the competence to carryout tests and orcalibrations. There are 15 management requirements and 10 technical requirements. Theserequirements outline what a laboratory must do to become accredited. Management system refers to theorganization's structure for managing its processes or activities that transform inputs of resources into aproduct or service which meets the organization's objectives, such as satisfying the customer's quality

    requirements, complying with regulations, or meeting environmental objectives.The CMMI (Capability Maturity Model Integration) model is widely used to implement Quality Assurance(PPQA) in an organization. The CMMI maturity levels can be divided in to 5 steps, which a company canachieve by performing specific activities within the organization.

    Preventing quality problems

    Quality assurance, in its broadest sense, is any action taken to prevent quality problems from occurring. In practice, this means devising systems for carrying out tasks which directly affect product quality.A simple example of quality assurance is a cooking recipe. A recipe is a system for preparing a particular dish.It describes the ingredients and utensils necessary to prepare the food, the method of cooking it, how to testwhen it is ready, how to store it, and how to serve it. Cooking to a recipe produces better and more consistentresults. And the same applies to using systems in other situations.To implement systems for an organisation, you need to carry out three basic steps: first develop the system;second, document it (this takes the form of policies, procedures, and reference information); and third, inform,instruct, and train staff to use it. This process is illustrated below.

    Systems of various kinds are, of course, already an integral part of all organisations. But in most cases they donot thoroughly address quality as a separate and important issue. This changes when an organisation embracesand pursues quality assurance. Quality assurance does not only apply to products. Services, and even "non-production" activities such as administration and sales, benefit from a quality assurance approach.Quality Assurance standards

    Quality Assurance Standards are published documents which describe in detail what systems should be used bya company to manage quality.The table below lists some of the QA standards issued by various bodies.

    These Standards exist because many large organisations will not buy from suppliers who cannot give themassurance that they have systems which support quality. These large organisations include Government DefenseDepartments, Health Departments, car manufacturers such as Ford, Toyota, and General Motors, andAerospace companies such as Boeing and Lockheed.Until the mid 1980's these large organisations published their own standards or codes for suppliers to follow,and their staff would audit supplier companies regularly to make sure they followed the code. It was not

    unusual for a supplier to be audited separately by a number of larger customers, all with their own qualitysystem codes. In some instances suppliers hosted 30 or 40 quality system audits a year from all their majorcustomers. To reduce the number of audits to which individual suppliers were subjected, the InternationalOrganisation for Standards (ISO) published a series of standards in 1987 known as ISO 9000. Most largepurchasing organisations accepted this worldwide standard and ceased to issue their own codes. They alsoceased carrying out their own audits and accepted the findings of independent audit companies engaged bysupplier companies to check their systems against the ISO 9000 standards. This allowed supplier companies toreduce the number of audits to two or three per year.

    Some of the independent audit companies operating in Australia are Lloyds Quality Assurance Services,Quality Assurance Services (QAS), Bureau Veritas, Benchmark Certification, SGS QA Services, and NationalAssocation of Testing Authorities (NATA).

    The ISO 9000 series of QA standards

    ISO 9000 is the name of a series of QA standards recognised by over 200 countries around the world andadopted as their national standards for QA. In Australia this series has been named the AS 3900 series, but thiswill change in mid 1995 to the AS/NZ/ISO 9000 series to identify it more closely with the internationalstandard. AS 3900 and ISO 9000 have identical contents.

    The most important document in the ISO 9000 series is ISO 9001. This is the code against which audits areactually carried out (two other documents, ISO 9002 and ISO 9003, can also be audited against but these are'cut down' versions of ISO 9001 for companies which do not need to comply with the entire code). All the otherdocuments in the ISO 9000 series provide guidelines and explanations for how to apply ISO 9001.

    The principal features of ISO 9001 are that it, takes the basic principle of QA (the need for documented systemsto support QA), and adds requirements to control system documentation to make sure it is kept up-to-daterequires companies to carry out their own internal audits of their QA system to make sure it is working properly

    requires the QA system to be constantly monitored to ensure that it is effective, and that changes are constantlymade to improve itThese requirements are illustrated in the diagram below.

    In addition, ISO 9001 requires organisations to include documented systems in their QA system to cover allaspects of: basic quality control (inspection, testing, test records, traceability, etc.) a product's life cycle fromthe time negotiations start with the customer, through the design process, purchasing of raw materials,production, storage, and final deliveryWhen is QA appropriate

    The basic principle of QA - working out the best course of action beforehand and communicating it reliably toall those concerned - should be applied whenever a planned process is complex, has implications for other

    processes, or has wide or repetitious application. Beyond this, the decision to follow the specifications in acomprehensive published QA standard rests on your organisation's answers to the following questions:

    Is your organisation prepared to invest the time to follow the formal discipline required?

    Does the law require your organisation's compliance with a specific standard (pharmaceuticalmanufacturers must comply with the Code of GMP)?

    Do your customers insist on your organisation's compliance with a standard (many large companies

    and Government Agencies and Departments have a policy of preference for suppliers with QA

    Certification)?How to implement a QA system

    You can implement quality assurance in a general way by identifying the tasks, processes, or systems critical tothe business and writing clear guidelines and instructions for staff. Use these guidelines and instructions fortraining and day-to-day reference. For the tasks, processes and systems covered, this will reduce:

    1.the number of errors 2.waste of time and materials associated with errors

    3.the number of customer complaints 4. the number of problems to fix

    the time spent on giving day-to-day instructions

    the time needed to improve processes and systems (by establishing a stable base)You can then take this general principle of clearly documenting tasks, processes and systems to the next levelby using ISO 9000 (or another appropriate QA system code) as a model for covering all aspects of quality, and

    for establishing formal disciplines for controlling information accuracy, and reviewing and improving systems.The two levels of implementation are summarised in the table below. The table also lists the additional thingsyou can do to make your quality assurance easier to apply and even more effective.

    ISO 9000 Series

    ISO 9000 is a family ofstandards forquality management systems. ISO 9000 is maintained by ISO, theInternational Organization for Standardization and is administered by accreditation and certification bodies.The rules are updated, as the requirements motivate changes over time. Some of the requirements in ISO9001:2008 (which is one of the standards in the ISO 9000 family) include

    a set of procedures that cover all key processes in the business;

    monitoring processes to ensure they are effective;

    keeping adequate records;

    checking output for defects, with appropriate and corrective action where necessary;

    regularly reviewing individual processes and the quality system itself for effectiveness;

    and

    facilitating continual improvementA company or organization that has been independently audited and certified to be in conformance withISO 9001 may publicly state that it is "ISO 9001 certified" or "ISO 9001 registered". Certification to anISO 9001 standard does not guarantee any quality of end products and services; rather, it certifies thatformalized business processes are being applied.Although the standards originated in manufacturing, they are now employed across several types oforganizations. A "product", in ISO vocabulary, can mean a physical object, services, orsoftware.Contents of ISO 9001

    Supporting Documentation QOP-85-03 Corrective and Preventive Actions[edit] 1987 version

    ISO 9000:1987 had the same structure as the UK Standard BS 5750, with three 'models' for qualitymanagement systems, the selection of which was based on the scope of activities of the organization:

    ISO 9001:1987 Model for quality assurance in design, development, production, installation, andservicing was for companies and organizations whose activities included the creation of newproducts.

    ISO 9002:1987 Model for quality assurance in production, installation, and servicing hadbasically the same material as ISO 9001 but without covering the creation of new products.

    ISO 9003:1987 Model for quality assurance in final inspection and test covered only the finalinspection of finished product, with no concern for how the product was produced.

    ISO 9000:1987was also influenced by existing U.S. and otherDefense Standards ("MIL SPECS"), and sowas well-suited to manufacturing. The emphasis tended to be placed on conformance with proceduresrather than the overall process of managementwhich was likely the actual intent.[citation needed]

    [edit] 1994 version

    ISO 9000:1994 emphasized quality assurance via preventive actions, instead of just checking final product,and continued to require evidence of compliance with documented procedures. As with the first edition, thedown-side was that companies tended to implement its requirements by creating shelf-loads of proceduremanuals, and becoming burdened with an ISO bureaucracy. In some companies, adapting and improvingprocesses could actually be impeded by the quality system.[citation needed]

    [edit] 2000 version

    ISO 9001:2000 combines the three standards 9001, 9002, and 9003 into one, called 9001. Design anddevelopment procedures are required only if a company does in fact engage in the creation of newproducts. The 2000 version sought to make a radical change in thinking by actually placing the concept ofprocess management front and center ("Process management" was the monitoring and optimizing of acompany's tasks and activities, instead of just inspecting the final product). The 2000 version also demandsinvolvement by upper executives, in order to integrate quality into the business system and avoiddelegation of quality functions to junior administrators. Another goal is to improve effectiveness via process performance metrics numerical measurement of the effectiveness of tasks and activities.Expectations of continualprocess improvement and tracking customer satisfaction were made explicit.The ISO 9000 standard is continually being revised by standing technical committees and advisory groups,who receive feedback from those professionals who are implementing the standard.[1]ISO 9001:2008 only introduces clarifications to the existing requirements of ISO 9001:2000 and somechanges intended to improve consistency with ISO 14001:2004. There are no new requirements.Explanation of changes in ISO 9001:2008. A quality management system being upgraded just needs to bechecked to see if it is following the clarifications introduced in the amended version.[edit] Certification

    ISO does not itself certify organizations. Many countries have formed accreditation bodies to authorizecertification bodies, which audit organizations applying for ISO 9001 compliance certification. Althoughcommonly referred to as ISO 9000:2000 certification, the actual standard to which an organization's quality

    management can be certified is ISO 9001:2008. Both the accreditation bodies and the certification bodiescharge fees for their services. The various accreditation bodies have mutual agreements with each other toensure that certificates issued by one of the Accredited Certification Bodies (CB) are accepted worldwide.The applying organization is assessed based on an extensive sample of its sites, functions, products,services and processes; a list of problems ("action requests" or "non-compliance") is made known to themanagement. If there are no major problems on this list, or after it receives a satisfactory improvement planfrom the management showing how any problems will be resolved, the certification body will issue an ISO9001 certificate for each geographical site it has visited.An ISO certificate is not a once-and-for-all award, but must be renewed at regular intervals recommendedby the certification body, usually around three years. There are no grades of competence within ISO 9001:either a company is certified (meaning that it is committed to the method and model of quality managementdescribed in the standard), or it is not. In this respect, it contrasts with measurement-based quality systemssuch as the Capability Maturity Model.

    [edit] AuditingTwo types of auditing are required to become registered to the standard: auditing by an externalcertification body (external audit) and audits by internal staff trained for this process (internal audits). Theaim is a continual process of review and assessment, to verify that the system is working as it's supposed to,find out where it can improve and to correct or prevent problems identified. It is considered healthier forinternal auditors to audit outside their usual management line, so as to bring a degree of independence totheir judgments.Under the 1994 standard, the auditing process could be adequately addressed by performing "complianceauditing":

    Tell me what you do (describe the business process)

    Show me where it says that (reference the procedure manuals)

    Prove that this is what happened (exhibit evidence in documented records)The 2000 standard uses a different approach. Auditors are expected to go beyond mere auditing for rote

    "compliance" by focusing on risk, status and importance. This means they are expected to make morejudgments on what is effective, rather than merely adhering to what is formally prescribed. The differencefrom the previous standard can be explained thus:Under the 1994 version, the question was broadly "Are you doing what the manual says you should bedoing?", whereas under the 2000 version, the question is more "Will this process help you achieve yourstated objectives? Is it a good process or is there a way to do it better?"[edit] Industry-specific interpretations

    The ISO 9001 standard is generalized and abstract. Its parts must be carefully interpreted, to make sensewithin a particular organization. Developing software is not like making cheese or offering counseling

    services; yet the ISO 9001 guidelines, because they are business, management guidelines can be applied toeach of these. Diverse organizationspolice departments (US), professional soccer teams (Mexico) andcity councils (UK)have successfully implemented ISO 9001:2000 systems.Over time, various industry sectors have wanted to standardize their interpretations of the guidelines withintheir own marketplace. This is partly to ensure that their versions of ISO 9000 have their specificrequirements, but also to try and ensure that more appropriately trained and experienced auditors are sent toassess them.

    The TickIT guidelines are an interpretation of ISO 9000 produced by the UK Board of Trade tosuit the processes of the information technology industry, especially software development.

    AS9000 is the Aerospace Basic Quality System Standard, an interpretation developed by majoraerospace manufacturers. Those major manufacturers include AlliedSignal, Allison Engine,Boeing, General Electric Aircraft Engines, Lockheed-Martin, McDonnell Douglas, NorthropGrumman, Pratt & Whitney, Rockwell-Collins, Sikorsky Aircraft, and Sundstrand. The currentversion is AS9100.

    PS 9000 is an application of the standard for Pharmaceutical Packaging Materials. ThePharmaceutical Quality Group (PQG) of the Institute of Quality Assurance (IQA) has developedPS 9000:2001. It aims to provide a widely accepted baseline GMP framework of best practicewithin the pharmaceutical packaging supply industry. It applies ISO 9001: 2000 to pharmaceuticalprinted and contact packaging materials.

    QS 9000 is an interpretation agreed upon by major automotive manufacturers (GM, Ford,Chrysler). It includes techniques such as FMEA and APQP. QS 9000 is now replaced by ISO/TS16949.

    ISO/TS 16949:2009 is an interpretation agreed upon by major automotive manufacturers(American and European manufacturers); the latest version is based on ISO 9001:2008. Theemphasis on a process approach is stronger than in ISO 9001:2008. ISO/TS 16949:2009 containsthe full text of ISO 9001:2008 and automotive industry-specific requirements.

    TL 9000 is the Telecom Quality Management and Measurement System Standard, aninterpretation developed by the telecom consortium, QuEST Forum. The current version is 4.0 andunlike ISO 9001 or the above sector standards, TL 9000 includes standardized productmeasurements that can be benchmarked. In 1998 QuEST Forum developed the TL 9000 QualityManagement System to meet the supply chain quality requirements of the worldwidetelecommunications industry.

    ISO 13485:2003is the medical industry's equivalent of ISO 9001:2000. Whereas the standards itreplaces were interpretations of how to apply ISO 9001 and ISO 9002 to medical devices, ISO13485:2003 is a stand-alone standard. Compliance with ISO 13485 does not necessarily meancompliance with ISO 9001:2000.

    ISO/IEC 90003:2004 provides guidelines for the application of ISO 9001:2000 to computersoftware.

    ISO/TS 29001 is quality management system requirements for the design, development,production, installation and service of products for the petroleum, petrochemical and natural gasindustries. It is equivalent to API Spec Q1 without the Monogram annex.

    [edit] Effectiveness

    The debate on the effectiveness of ISO 9000 commonly centers on the following questions:1. Are the quality principles in ISO 9001:2000 of value? (Note that the version date is important: in

    the 2000 version ISO attempted to address many concerns and criticisms of ISO 9000:1994).

    2. Does it help to implement an ISO 9001:2000 compliant quality management system?3. Does it help to obtain ISO 9001:2000 certification?Effectiveness of the ISO system being implemented depends on a number of factors, the most significant ofwhich are:

    1. Commitment of Senior Management to monitor, control, and improve quality. Organizations thatimplement an ISO system without this desire and commitment, often take the cheapest road to geta certificate on the wall and ignore problem areas uncovered in the audits.

    2. How well the ISO system integrates into their business practices. Many organizations thatimplement ISO try to make their system fit into a cookie-cutter quality manual rather than create a

    manual that documents existing practices and only adds new processes to meet the ISO standardwhen necessary.

    3. How well the ISO system focuses on improving the customer experience. The broadest definitionof quality is "Whatever the customer perceives good quality to be". This means that you don'tnecessarily have to make a product that never fails, some customers will have a higher tolerancefor product failures if they always receive shipments on-time, or some other dimension ofcustomer service. Your ISO system should take into account all areas of the customer experience,the industry expectations, and seek to improve them on a continual basis. This means taking intoaccount all processes that deal with the three stakeholders (your customers, your suppliers, andyour organization), only then will you be able to sustain improvements in your customerexperience.

    4. How well the auditor finds and communicates areas of improvement. Now, ISO auditors may notprovide consulting to the clients they audit, however, there is the potential for auditors to point outareas of improvement. Many auditors simply rely on submitting reports that indicate complianceor non-compliance with the appropriate section of the standard, however, to most executives, thisis like speaking a foreign language. Auditors that can clearly identify and communicate areas ofimprovement in language and terms executive management understands allows the companiesthey audit to act on improvement initiatives. When management doesn't understand why they werenon-compliant and the business implications, they simply ignore the reports and focus on whatthey do understand.

    [edit] Advantages

    It is widely acknowledged that proper quality management improves business, often having a positiveeffect on investment, market share, sales growth, sales margins, competitive advantage, and avoidance oflitigation.The quality principles in ISO 9000:2000 are also sound, according to Wade and Barnes, who saythat "ISO 9000 guidelines provide a comprehensive model for quality management systems that can makeany company competitive implementing ISO often gives the following advantages:

    1. Create a more efficient, effective operation2. Increase customer satisfaction and retention3. Reduce audits4. Enhance marketing5. Improve employee motivation, awareness, and morale6. Promote international trade7. Increases profit

    8. Reduce waste and increases productivity.[edit] Problems

    A common criticism of ISO 9001 is the amount of money, time and paperwork required for registration. [1]

    According to Barnes, "Opponents claim that it is only for documentation. Proponents believe that if acompany has documented its quality systems, then most of the paperwork has already been completed."[2]

    ISO 9001 is not in any way an indication that products produced using its certified systems are any good. Acompany can intend to produce a poor quality product and providing it does so consistently and with theproper documentation can put an ISO 9001 stamp on it. According to Seddon, ISO 9001 promotesspecification, control, and procedures rather than understanding and improvement. [3][4] Wade argues thatISO 9000 is effective as a guideline, but that promoting it as a standard "helps to mislead companies intothinking that certification means better quality, ... [undermining] the need for an organization to set its ownquality standards." [5]Paraphrased, Wade's argument is that reliance on the specifications of ISO 9001 doesnot guarantee a successful quality system.

    While internationally recognized, most US consumers are not aware of ISO 9000 and it holds no relevanceto them. The added cost to certify and then maintain certification may not be justified if product end usersdo not require ISO 9000. The cost can actually put a company at a competitive disadvantage whencompeting against a non ISO 9000 certified company.The standard is seen as especially prone to failure when a company is interested in certification beforequality.[3] Certifications are in fact often based on customer contractual requirements rather than a desire toactually improve quality.[2][6] "If you just want the certificate on the wall, chances are, you will create apaper system that doesn't have much to do with the way you actually run your business," said ISO's RogerFrost.[6] Certification by an independent auditor is often seen as the problem area, and according to Barnes,

    "has become a vehicle to increase consulting services." [2] In fact, ISO itself advises that ISO 9001 can beimplemented without certification, simply for the quality benefits that can be achieved.[7]

    Another problem reported is the competition among the numerous certifying bodies, leading to a softerapproach to the defects noticed in the operation of the Quality System of a firm.Abrahamson[8] argued that fashionable management discourse such as Quality Circles tends to follow alifecycle in the form of abell curve, possibly indicating a management fad.[edit] Summary

    A good overview for effective use of ISO 9000 is provided by Barnes: "Good business judgment is neededto determine its proper role for a company. Is certification itself important to the marketing plans of thecompany? If not, do not rush to certification Even without certification, companies should utilize the ISO9000 model as a benchmark to assess the adequacy of its quality programs."

    Capability Maturity Model (CMM)

    CMM (Capability Maturity Model) is a model of process maturity for software development - anevolutionary model of the progress of a companys abilities to develop software.

    In November 1986, the American Software Engineering Institute (SEI) in cooperation with MitreCorporation created the Capability Maturity Model for Software.

    Development of this model was necessary so that the U.S. federal government could objectively evaluatesoftware providers and their abilities to manage large projects.

    Many companies had been completing their projects with significant overruns in schedule and budget. Thedevelopment and application of CMM helps to solve this problem.

    The key concept of the standard is organizational maturity. A mature organization has clearly definedprocedures for software development and project management. These procedures are adjusted and perfected as required.

    In any software development company there are standards for processes of development, testing, andsoftware application; and rules for appearance of final program code, components, interfaces, etc.

    The CMM model defines five levels of organizational maturity:

    1. Initial level is a basis for comparison with the next levels. In an organization at the initial level,conditions are not stable for the development of quality software. The results of any projectdepend totally on the managers personal approach and the programmers experience, meaning thesuccess of a particular project can be repeated only if the same managers and programmers areassigned to the next project. In addition, if managers or programmers leave the company, thequality of produced software will sharply decrease. In many cases, the development process comes

    down to writing code with minimal testing.2. Repeatable level. At this level, project management technologies have been introduced in a

    company. That project planning and management is based on accumulated experience and thereare standards for produced software (these standards are documented) and there is a special qualitymanagement group. At critical times, the process tends to roll back to the initial level.

    3. Defined level. Here, standards for the processes of software development and maintenance areintroduced and documented (including project management). During the introduction of standards,a transition to more effective technologies occurs. There is a special quality managementdepartment for building and maintaining these standards. A program of constant, advancedtraining of staff is required for achievement of this level. Starting with this level, the degree oforganizational dependence on the qualities of particular developers decreases and the process doesnot tend to roll back to the previous level in critical situations.

    4. Managed level. There are quantitative indices (for both software and process as a whole)

    established in the organization. Better project management is achieved due to the decrease ofdigression in different project indices. However, sensible variations in process efficiency may bedifferent from random variations (noise), especially in mastered areas.

    5. Optimizing level. Improvement procedures are carried out not only for existing processes, butalso for evaluation of the efficiency of newly introduced innovative technologies. The main goalof an organization on this level is permanent improvement of existing processes. This shouldanticipate possible errors and defects and decrease the costs of software development, by creatingreusable components for example.

    The Software Engineering Institute (SEI) constantly analyzes the results of CMM usage by differentcompanies and perfects the model taking into account accumulated experienceCapability Maturity Model (CMM) - WIKKI

    The Capability Maturity Model (CMM) is a service markowned by Carnegie Mellon University (CMU)and refers to a development model elicited from actual data. The data were collected from organizations

    that contracted with the U.S. Department of Defense, who funded the research, and they became thefoundation from which CMU created the Software Engineering Institute (SEI). Like any model, it is anabstraction of an existing system.When it is applied to an existing organization's software development processes, it allows an effectiveapproach toward improving them. Eventually it became clear that the model could be applied to otherprocesses. This gave rise to a more general concept that is applied to business processes and to developingpeople.Overview

    The Capability Maturity Model (CMM) was originally developed as a tool for objectively assessing theability of government contractors' processes to perform a contracted software project. The CMM is basedon the process maturity framework first described in the 1989 book Managing the Software Process byWatts Humphrey. It was later published in a report in 1993 (Technical Report CMU/SEI-93-TR-024 ESC-TR-93-177 February 1993, Capability Maturity Model SM for Software, Version 1.1) and as a book by the

    same authors in 1995.Though the CMM comes from the field ofsoftware development, it is used as a general model to aid inimproving organizational business processes in diverse areas; for example in software engineering, systemengineering, project management, software maintenance, risk management, system acquisition, informationtechnology (IT), services, business processes generally, and human capital management. The CMM has been used extensively worldwide in government, commerce, industry and software developmentorganizations.CMM-rated organizations

    An organization may be assessed by an SEI-Authorized Lead Appraiser, and will then be able to claim thatthey have been assessed as CMM level X, where X is from 1 to 5. Although sometimes called CMM-certification, the SEI doesn't use this term due to certain legal implications.The SEI maintains a list[1] of organizations assessed for CMM since 2006.Many India based software offshoring companies were amongst the first organizations to receive thehighest CMM rating.History

    The need for software processes prior to CMM

    In the 1970s the use of computers became more widespread, flexible and less expensive. Organizations began to adopt computerized information systems, and the demand for software development grewsignificantly. The processes for software development were in their infancy, with few standard or "bestpractice" approaches defined.As a result, the growth was accompanied by growing pains: project failure was common, and the field ofcomputer science was still in its infancy, and the ambitions for project scale and complexity exceeded themarket capability to deliver. Individuals such as Edward Yourdon, Larry Constantine, Gerald Weinberg,Tom DeMarco, and David Parnas began to publish articles and books with research results in an attempt toprofessionalize the software development process.In the 1980s, several US military projects involving software subcontractors ran over-budget and werecompleted much later than planned, if they were completed at all. In an effort to determine why this wasoccurring, the United States Air Force funded a study at the SEI.Precursor to CMM

    The Quality Management Maturity Grid was developed by Philip Crosby in his book "Quality Is Free".[2]

    Note that the first application of a staged maturity model to IT was not by CMM/SEI, but rather by RichardL. Nolan, who, in 1973 published the Stages of growth model for IT organizations.[3]

    Watts Humphrey began developing his process maturity concepts during the later stages of his 27 yearcareer at IBM. (References needed)The development of CMM at SEI

    Active development of the model by the US Department of Defense Software Engineering Institute (SEI)began in 1986 when Humphrey joined the Software Engineering Institute located at Carnegie MellonUniversity in Pittsburgh, Pennsylvania after retiring from IBM. At the request of the U.S. Air Force hebegan formalizing his Process Maturity Framework to aid the U.S. Department of Defense in evaluating thecapability of software contractors as part of awarding contracts.The result of the Air Force study was a model for the military to use as an objective evaluation of software

    subcontractors' process capability maturity. Humphrey based this framework on the earlier QualityManagement Maturity Grid developed by Philip B. Crosby in his book "Quality Is Free". [2] However,Humphrey's approach differed because of his unique insight that organizations mature their processes instages based on solving process problems in a specific order. Humphrey based his approach on the stagedevolution of a system of software development practices within an organization, rather than measuring thematurity of each separate development process independently. The CMM has thus been used by differentorganizations as a general and powerful tool for understanding and then improving general businessprocess performance.Watts Humphrey's Capability Maturity Model (CMM) was published in 1988[4] and as a book in 1989, inManaging the Software Process.[5]

    Organizations were originally assessed using a process maturity questionnaire and a Software CapabilityEvaluation method devised by Humphrey and his colleagues at the Software Engineering Institute (SEI).The full representation of the Capability Maturity Model as a collection of defined process areas and

    practices at each of the five maturity levels was initiated in 1991, with Version 1.1 being completed inJanuary 1993.[6] The CMM was published as a book[7] in 1995 by its primary authors, Mark C. Paulk,Charles V. Weber, Bill Curtis, and Mary Beth Chrissis.CMM is superseded by CMMI

    The CMM model proved useful to many organizations, but its application in software development hassometimes been problematic. Applying multiple models that are not integrated within and across anorganization could be costly in terms of training, appraisals, and improvement activities. The CapabilityMaturity Model Integration (CMMI) project was formed to sort out the problem of using multiple CMMs.
