Introduction

“Best Practice” models describe an “ideal” organization and its operation

Best Practice models useful for: Information / KnowledgeAppraisal / Assessment Improvement Guide

“All models are wrong, but some are useful.” - George Box

Introduction -2 Parent of ‘maturity models’ – Philip Crosby

Wrote “Quality is Free” in 1979 Crosby’s Quality Management Maturity Grid:

UncertaintyAwakeningEnlightenmentWisdomCertainty

OPM3 Review

Organizational Project Management Maturity Model (OPM3)

First released in 2003 Built upon Project Management Body of

Knowledge (PMBOK®)Standards first released 1987Guide first released 1996

602 April 2009

OPM3 Review -2 Created & Maintained by PMI (Project

Management Institute) Not for profit private institute Best practices work in project management

OPM3 focus is on organizational integration of: Project Program Portfolio

OPM3 defines 4 stages of maturity

702 April 2009

OPM3 Review -3 OPM3 defines 4 stages of maturity

StandardizeMeasureControlContinuously Improve

OPM3 matrixes maturity stages, project/program/portfolio, and incremental capabilities

802 April 2009

OPM3 Review -4

OPM3 model and PMBOK Guide provide information / knowledge of best practices

OPM3 includes assessment process information

OPM3 model includes improvement process

PMI provides many related resources

CMMI Review Capability Maturity Model® Integration First released in 2000 Evolved from CMM® for Software

Initial version in 1987First released 1993

Integrates Best Practices from Software EngineeringSystems Engineering (EIA-731)AcquisitionOther disciplines (e.g., project management)

1002 April 2009

CMMI Review -2

Created & Maintained by SEI (Software Engineering Institute) Federally funded Research & Development Center

since 1984 Best practices work in management, engineering, and

acquisition

CMMI focus is Process & Process Improvement CMMI® defines 5 stages of maturity

1102 April 2009

CMMI Review -3

CMMI differentiates Best Practices between organization and project(s), i.e. Organizational …Training (ML3)Process Focus (ML3)Process Definition (ML3)Process Performance (ML4) Innovation & Deployment (ML5)

1202 April 2009

CMMI Review -4

CMMI model provides information / knowledge of best practices

Standard CMMI Appraisal Method for Process Improvement (SCAMPISM) provides assessment process

CMMI model and related SEI resources (e.g., IDEAL model) provide improvement process

Similarities: CMMI & OPM3 Summarize & organize best practices as a

frameworkNeither are prescriptive

Based on (approx.) 5 levels of process maturitySee Crosby’s maturity gridLevels build on each other – can’t skip

foundational best practices!

Similarities: CMMI & OPM3 -2

Not specific to a particular industryBoth have “extensions” or “constellations” for

particular applications Differentiate “organizational” from “project”

levels of applicationSee PMI Project Management Body of

Knowledge (PMBOK® Guide) for project details

Similarities: Structure Examples

OPM3 Best Practice:“Manage Project Resource Pool”Capability: “Match Project Resource

Requirements” CMMI (Generic) Goal:

“Institutionalize a Managed Process”Generic Practice: “Provide Resources”

Differences

Accessibility:CMMI is federally funded – many resources are

“free”OPM3 is PMI funded – very tightly controlled

Focus:CMMI focus is operational implementation of

processesOPM3 emphasis is linking project / program /

portfolio to organization strategic objectives

2102 April 2009

Differences -2

CMMI has 3 “constellations”:DevelopmentAcquisitionServices (just released)

CMMI has 2 representations:Staged (=> 5 Maturity Levels)Continuous (=> 6 Capability Levels)

2202 April 2009

Differences -3 OPM3 defines a matrixed 3 dimensional

maturity progressionProcess improvement progression “stages”

Comparable to CMMI Maturity Levels

Organizational “domains”: Project Program Portfolio

Incremental “Capabilities” progression ‘Somewhat like’ CMMI Capability Levels

2302 April 2009

Summary

CMMI & OPM3 are well-defined, ‘useful’ models

Both CMMI & OPM3 provide knowledge, assessment, and improvement resources

Significant similarities in purpose and structure of CMMI & OPM3

Manageable differences between CMMI & OPM3

Can apply either – or both – successfully!
