What Is Process?

• How do you define process?

5
General Definition of Process

• A process is a set of practices performed to
  achieve a given purposeit may
  include,tools,methods,materials and/or people.

6
Quality Leverage Points

• While process is often described as a leg of
  the process-people-technology triad, it may also
  be consider the glue that unifies the other
  aspects.
• PEOPLE Everyone realizes
  the importance
• of having a
  motivated,quality work
• force but even
  our finest people
• cant perform
  at their best when
• PROCESS TECHNOLOGY the process is not
  understood or
• Major determinants of product cost, operating
  at its best.
• Schedule,and quality

7
Why Focus on Process?

• Process provides a constructive,high-leverage
  focus
• as opposed to a focus on people
• - Your work force, on the average, is as
  good as
• it is trained to be.
• - Working harder is not the answer.
• - Working smarter, through process, is the
  answer
• as opposed to a focus on technology
• - Technology applied without a suitable
  roadmap
• will not result in significant payoff.
• - Technology provides the most benefit in
  the
• context of an appropriate process roadmap.

8
The Process Management Premise

• The quality of a system is highly influenced by
• The quality of the process used to acquire,
  develop,
• And maintain it.
• This premise implies a focus on processes as well
• As on products.
• This is a long-established premise in
  manufacturing
• Belief in this premise is visible worldwide in
  quality
• movements in manufacturing and service
  industries
• (e.g., ISO standards).

10
Early Process Improvement

• The theories of process management are a
  synthesis
• of the concepts of Deming, Crosby, Juran, and
  others.
• Over the past 30 years, these theories have been
  used
• to address problems common to many organizations.
• Solutions have been discovered, but a gap existed
  
• between the state of the practice and the state
  of the
• art.
• Many of these concepts have been used to build
• process-improvement models.

11
What Is a Process Model?

• A model is a structured collection of elements
  that
• describes characteristics of effective processes.
• Processes included are those proven by experience
  to
• be effective.

12
How Is a Model Used?

• A model is used
• to help set process improvement objectives and
• priorities
• to help ensure stable, capable, and mature
• processes
• as a guide for improvement of project and
• organizational processes
• with an appraisal methodology to diagnose the
• state of improvement efforts

13
Why Is a Model Important?

• A model provides
• a place to start
• the benefit of a communitys prior experiences
• a common language and a shared vision
• a framework for prioritizing actions
• a way to define what improvement means for your
• organization
• All models are wrong some are useful.
• -George Box

14
Multiple Models

• The SEI, ISO, EIA, and other organizations have
• Generated models
• based on widely-accepted practices
• with a proven history of benefits
• These successful efforts generated a number of
• Related models.

Why Use CMMI?

• CMMI provides guidance for improving your
• organizations processes and your ability to
• manage the develoment,acquisition,and
• Maintenance of products or services.
• CMMI places proven approaches into a structure
  that
• - helps your organization exrmine the
  effectiveness
• - establishes priorities for improvement
• - helps your implement these improvements

CMM Intergration Project
SM

• The CMMI Intergration Project was formed to
• build an initial set of intergrated models
• establish a framework to enable intergration of
  future
• models
• Create an associated set of appraisal and
  training products
• Source models severing as the starting point for
  CMMI
• Where
• SW-CMMI (software) V2.0 Draft C
• EIA/IS-731 (systems engineering)
• IPD-CMM (intergrated product development) V 0.98
  

19
The CMMI Product Team

• Membership from
• Industry
• U.S. government
• Software Engineering Institute
• Membership characterisitics
• Average of about 21 years experience
• from organizations with soild process improvement
  credentials

20
Development Strategy

• Base the models contents on current best practies
  as
• represented in widely-accepted soyrce models.
• Conduct public reviews of the models.
• Conduct pliots of the products suite prior to
  official
• Product release.
• Update the product suite based on feedback from
  pilots
• and reviewers.
• Release v 1.0 of the rpoduct suite.
• Update the product suite based on feedback from
  users.
• Release v 1.1 of the updated product suite.

21
The CMMI Product Suite

• A framework for generating integrated products to
  
• support product and process improvement
• reference models
• training products
• appraisal methods
• These products share
• common terminology
• common components

22
CMMI Models

• Model options
• systems software engineering
• systems software engineering integrated
• product and process development (IPPD)
• systems software engineering integrated
• product and process development supplier
• sourcing(SS)
• Representation options
• staged
• continuous
• This course will address models that include
  systems
• and software engineering, IPPD, and supplier
• sourcing.

23
Special CMMI Terminology

• Each body of knowledge related to produst or
  porcess
• development in CMMI is considered a discipline.
• Software engineering,systems engineering,intergrat
  ed
• Product and process development,and supplier
• Sourcing are all considered disciplines.

24
Intergration Means Organization Change

• As product complexity increases,the need for
• multidisciplinary work groups also grows.
• Real organization change is required for an
  intergrated
• engineering apporach to succeed.
• Proccesses cannot simply be intergrated on paper.

25
Break on Through to the other Side

• When an organization moves to
• CMMI, it acknowledges a
• business need to improve
• management processes and
• place the focus where it
• belongs
• on process and product.

26
CMMI in a Nutshell

• A CMMI model provides a structured view of
• Process improvement.
• CMMI can help
• set process improvement goals and priorities
• provide guidance for quality processes
• provide a yardstick for assessing current
• practices
