Summary

What Is Process?

How do you define process?

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.

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

PROCESS TECHNOLOGY the process is not understood or

Major determinants of product cost, operating “at its best.”Schedule,and quality

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.

The Process Management PremiseThe 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).

Summary

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 theart.

Many of these concepts have been used to buildprocess-improvement models.

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.

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

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

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.

Summary

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

CMM Intergration Project

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 productsSource models severing as the starting point for CMMIWhere• SW-CMMI (software) V2.0 Draft C• EIA/IS-731 (systems engineering)• IPD-CMM (intergrated product development) V 0.98

edentials

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 officialProduct release.

Update the product suite based on feedback from pilotsand 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.

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

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• continuousThis course will address models that include systems and software engineering, IPPD, and suppliersourcing.

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.

Intergration Means Organization ChangeAs 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.

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.

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
