New Assessment Requirements
• Aligned to needs of the organisation
Only assess where you can and want to improve
• Focus on improvement, not on levels
• More frequent assessments
• Smaller scope, more specific findings
• Lower cost

CMMI vs CMM SW
• Philosophy
– Integration of models
– Framework, toolbox
– Rating and improvement
– Common assessment method
• Structure
– Process Areas
– Goals & practices
– Staged & continuous
– Maturity & Capability level
• Scope
– Project Management
– Process management
– Engineering
– Support
« Incl. Systems Engineering
Replaces SW CMM,
SE-CMM, IPPD
CMM, and SA CMM
(not P-CMM)

Business Focus in CMMI
• Continues representation:
– Toolbox with Process Areas
– Pick only useful PAs
– Measure on Capability Level
• PA Purpose: Link to business goals
• But, business processes are lacking:
– Goal setting, strategies, customer focus
– Leadership, people development (P-CMM)
– Partnerships, environment, etc

Why did Ericsson choose CMMI?
• Continuous model: Focus on improvement
• Up to date collection of “Best Practices”
• Official standard (replace CMM SW 2.0 draft C)
• More suitable assessment method: Class C

– Process Management (7 PAs)
– Project Management (6 PAs)
– Requirement Management/Development (2 PAs)
– Engineering (4 PAs)
– Decision Analysis & Resolution (1 PA)
• 4 Assessors, 390 Mhrs (19.5 Hr per PA)
• 42 Interviewees, 159 Mhrs (3.8 Hr per person)
• 54 Strengths, 85 Weaknesses
• 70-80% of the finding led to actions
