The Evolution of CMM and CMMI-Based Process
Improvement

• Carnegic Mellon University USA DOD Supported
  Software Engineering Institute (SEI)
• 1987
• First CMM published as a technical report
• 1989
• Book on the software maturity framework published
• 1991
• CMM V. 1.0 for software published
• 1993/1994
• CMM V. 1.1 for software published, Personal
  Software Process (PSP developed by the SEI
• 1995
• New specialized CMM published by the SEI ,
  including CMMs for acquisition (SA-CMM), system
  engineering (SE-CMM), integrated product
  development (IPD-CMM) and human resource
  management (People-CMM)

CMM Structure

• What is the CMM?
• A model for process maturity
• A framework for reliable and consistent
  assessments
• A software industry, community owned guide
• A mechanism for identifying and adopting best
  practices
• Used to evaluate an organizations process
  maturity against global standard

8
CMM Structure

• Maturity Levels
• There are five maturity levels
• Well-defined evolutionary plateaus on a path to
  becoming a mature software Organization
• Each level is a layer in the foundation for
  continuous process improvement
• Achieving each level establishes a different
  component of the software process

CMM Appraisal Process

• The evaluators conduct interviews and review
  documents and other intermediate work products to
  obtain verifiable evidence of Commitment,
  Ability, Activity, Measures, Verifying
  information
• This is done for each KPA
• Six Steps
• Team Selection
• Maturity Questionnaires (Sample the CMM)
• Response Analysis
• On-Site Visit Interview and Document Reviews
• Finding Based on the CMM
• KPA Profile

CMMI Source Models

• Capability Maturity Model (CMM) for Software V2,
  draft C (SW-CMM)
• EIA Interim Standard 731, System Engineering
  Capability Model (SECM)
• Integrated Product Development Capability
  Maturity Model, draft V0.98 (IPD-CMM)
• Supplier Sourcing (SS)

CMMI Future Release and Updates

• After CMMI V1.1 has been published by December
  2001, the SEI will not produce any updates to
  the SW-CMM model for training

CMMI Terminology

• CMMI Models contain institutionalization
  (Generic) and implementation (Specific) parts
• Front matter
• Process Areas that contain
• Generic and Specific Goals
• Generic and Specific Practices(in Common
  Features in staged representation)
• Subpractices
• Notes
• Discipline-specific amplifications
• Glossary and tailoring guidelines

CMMI Model Representations

• The CMMI provides Two approaches to process
  improvement.
• process capability approach - continuous
  representation
• organizational maturity approach - staged
  representation

Taiwans System Life-cycle Processes
Characteristics

• Productivity High Implementation Phase
• Big Gap between Education (University Software
  Engineering) and Industry
• Opportunity for Improvement Phases System
  Requirements and Design, Planning and System
  Integration
• Has approximately 1000 software companies and a
  high volume of small companies
• No Training
• No Continuous Process Improvement Cost??
• Hardware and Software Not Balance in the world
  market
• Lack of Software Profile (Understanding)
• All National Programs such SI-Soft, e-Learning,
  etc depend on Core Technology - Software
