  1. Model-Based Process Improvement Module 2

  2. Module Objectives This module will enable students to recall • information about the history of CMMI • fundamentals of model-based process improvement • benefits of process improvement • concepts related to CMMI implementation Participants will have an opportunity to gain familiarity with process definition SM

  3. Topics Process Improvement Concepts Fundamentals of Model-Based Process Improvement CMMI Development Benefits of Process Improvement CMMI Model Representations and Basic Concepts Improvement Based on CMMI Models Defining Processes Summary

  4. 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 purpose;it 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 can’t perform at their best when PROCESSTECHNOLOGY 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).

  9. Topics Process Improvement Concepts Fundamentals of Model-Based Process Improvement CMMI Development Benefits of Process Improvement CMMI Model Representations and Basic Concepts Improvement Based on CMMI Models Defining Processes Summary

  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 community’s 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.

  15. Related Models Model Related models Software CMMSoftware AcquisitionCMM (SA—CMM) Team Software Process (TSP) People CMM (P-CMM) PersonalSoftwareProcess (PSP) Systems Engineering Capability Model (SECM) ISO 9000 seriesISO/IEC 12207 ISO 10011

  17. Why Use CMMI? CMMI provides guidance for improving your organization’s 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

  18. 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,intergrated 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
