WHAT IS CMMI? • Capability Maturity Model - Integration
CMMI Appraisal Types .1 • Continuous • Pick and choose desirable process areas • Capability level 0-5 • Capability level can be achieved without performing all practices • Not industry recognized • Primary appraisal method in India • 1 – 3 weeks to perform appraisal
CMMI Appraisal Types .2 • Staged • Maturity level • Level 1-5 (everyone is level 1) • All practices must be met for achieving the maturity level • Rating is for 3 years and then expires • Rigorous review of processes and artifacts • 2-4 weeks to perform appraisal
Specific versus Generic • Specific practices are process area dependent • (4 – 12 based on process area) • Generic practices are the same across all process areas • (10-12 practices based on level) • All SP’s and GP’s require same level of artifact coverage
CMMI Measures Process Maturity • 25 Process Areas in 4 general categories: • Process management (5 process areas) • Project management (8 process areas) • Engineering design (6 process areas) • Support functions (6 process areas) The measurement is the achievement of a limited number of Specific Goals in each process area, plus Generic Goals which apply to each process area.
Generic Practices • Identify and involve relevant stakeholders • Monitor and control the process • Objectively evaluate adherence • Review status with higher level management • Establish a defined process • Collect improvement information • Organizational policy • Plan the process • Provide resources • Assign Responsibility • Train the people • Manage configurations
Direct versus Indirect • Direct artifacts required for each SP and GP • Artifact that is directly attributable to performing the process described • Indirect artifact • Supporting artifact or resultant artifact of creating the direct artifact
Affirmations • Verbal confirmation of what the process definition • Interview process • No helper aids • Must understand other functional groups role in the organization • A valid answer is “I don’t know, but I know where to find the answer…..Procedure XYZ”
Appraisal Process • SCAMPI • Standard CMMI Appraisal Method for Process Improvement • Types of SCAMPI Appraisals • Class C – Single person to full team • Class B – Single person to full team • Class A – Minimum of four team members • Typically 6-8 team members
SCAMPI - C • Focused on Organizational processes only • Could be focused on specific process areas • Continuous model • Highlights ability to achieve a level;
SCAMPI - B • Detailed analysis of the process and plans • Looks at the organization as a whole • Identifies weaknesses and action items • Open for specific review items • Produces an action item list for the organization
SCAMPI - A • Produces maturity rating • Must have all data supplied • One chance to fix problems
