Sample CMMI appraisal report with feedback points
  • Provide more customer satisfaction
  • Land new clients more successfully
  • Have better productivity and efficiency with optimized processes
  • Cause less risk due to a well-defined structure
  • Incomplete: The problem should be well-defined
  • Initial: Requirements should be analyzed
  • Managed: High-level design should be completed
  • Defined: Low-level design should be completed
  • Quantitatively Managed: Functional coverage on requirements and test coverage should exceed the optimal point
  • Optimizing: The product should be well-maintained and regularly improved

CMMI For Development (CMMI-DEV)

CMMI Development is an integrated set of best practices that improves performance and key capabilities for organizations that develop products, components, and services. — CMMI Institute

To Institutionalize a Managed Process

  • Establish an Organizational Policy
  • Plan the Process: define and document the plan and the process description, review the plan with relevant stakeholders and get their agreement, and revise the plan if necessary.
  • Provide Resources
  • Assign Responsibility: assign overall or specific responsibility and authority and confirm that the people assigned to the responsibilities and authorities understand and accept them.
  • Train People
  • Control Work Products
  • Identify and Involve Relevant Stakeholders: identify stakeholders relevant to this process, share these identifications with project planners, and involve these relevant stakeholders as planned.
  • Monitor and Control the Process: evaluate actual progress and performance against the plan, review accomplishments and results, identify problems in the execution of the process, take corrective action when requirements and objectives are not being satisfied, and track corrective action to closure.
  • Objectively Evaluate Adherence
  • Review Status with Higher Level Management

To Institutionalize a Defined Process

  • Establish a Defined Process: select from the organization’s set of standard processes those processes that best meet the needs of the project, establish the defined process by tailoring the selected processes according to the organization’s tailoring guidelines.
  • Collect Process Related Experiences: store process and product measures in the organization’s measurement repository, submit documentation for the organization’s process asset library, document lessons learned from the process, and propose improvements.
