Recap

Why Projects Fail? An unrealistic deadline is established Changing customer requirements Ambiguous/incomplete requirements An honest underestimate of effort Predictable and/or unpredictable risks Technical difficulties Miscommunication among project staff Failure in project management

Comparison of CMMI Representations Staged Process improvement is measured using maturity levels. Maturity level is the degree of process improvement across a predefined set of process areas. Organizational maturity pertains to the “maturity” of a set of processes across an organization Continuous Process improvement is measured using capability levels. Capability level is the achievement of process improvement within an individual process area. Process area capability pertains to the “maturity” of a particular process across an organization.

CMM Maturity Levels OPTIMIZED – Process Improvement MANAGED – Process Measurement DEFINED – Process Definition REPEATABLE – Project Management INITIAL – Ad hoc Process

Project Management Concerns product quality? risk assessment? measurement? cost estimation? project scheduling? customer communication? staffing? other resources? project monitoring?
