Q

What is CMMI? Details

A

The Capability Maturity Model is a development of Software Engineering Institute (SEI) at Carnegie Mellon University.

  • Repeated misses of
    • Deliverydeadlines,
    • Developmentbudgets,and
    • Qualitytargets
  • in software projects triggered the DoD to develop a counter-measure
  • Goals of the DoD were to
    • Gain control over quality of software projects and
    • be able to assess delivery ability of contractors developping software

Model Goals:

  • Gain control over quality and project success through the assessment of maturity levels:
    • Evaluate the maturity of software development process and
    • apply targeted improvement of processes
  • Capability Maturity Model (CMM) goals
  • Increase quality and success rate
  • With increasing maturity it is expected that the predictive capability regarding

– schedule adeherence, – development cost, and – reaching quality targets is increased

Q

Success Factors of IT Projects are the Same All Over the Industry

A
  • Cost Agility
  • Quality/ Availability
  • Compliance
  • Agility
  • Innovation (Business Value of IT)
  • Security
  • Service Offering

Required for success: Ability to

  • measure
  • analyse
  • evaluate
  • improve

Pre-conditions are

  • processes
  • measurement methods
  • performance indicator

Based upon Process models

Q

Specifics for Process area

A

Every Process Area has a Set of Specific Goals which are Refined with Specific Practices:

  • Specific Goal 1 (SG 1):
    • The project is conducted using a defined process that is tailored from the organization’s set of standard processes
  • Specific Practices (SP) for SG 1 (selection):
    • SP1.1:Establishand maintain the project’s defined process from startup through the life of the project
    • SP1.2:Usethe organizational process assets and measurement repository for estimating and planning the project’s activities

Q

The Truth About Agile – From a CMMI Friendly Perspective

A

“Predictability does not arise from a detailed project plan up front that covers the entire project lifecycle”1

As long as the goals (generic or specific) are met,
neither the practices as such nor the typical CMMI work products are mandatory

CMMI Goal

  • Develop Customer requirements
    • Elicit needs, develop customer requirements
      • Backlog creation, refinement, user sotries, refinement with product owner during sprints
  • Develop Product requirements
    • allocate product requirements, identify interface requirement
      • see above
  • Establish estimate
    • determine estimate of cost and efforts
      • planning poker
  • Monitor Project against plan
    • conduct progress review, conduct milestone review
      • daily scrum, sprint and backlog burn-down chart
      • sprint review, sprint retroperspective
  • Perform peer reviews
    • conduct peer reviews
      • can be integrated into sprint work
  • very selected work products
    • perform verification
      • unit and user test

Q

What is CMMI? The Definition from the Institute that Should Know It Best

A
  • CMMI is a Framework for Improving Performance
    • The Capability Maturity Model Integration (CMMI®) is a […] performance improvement framework for competitive organizations that want to achieve high-performance operations.
  • A Model, Not a Process
    • CMMI does not provide a single process. Rather, the CMMI framework models what to do to improve your processes, not define your processes. CMMI is designed to compare an organization’s existing processes to proven best practices developed by members of industry, government, and academia;; reveal possible areas for improvement;; and provide ways to measure progress.
  • CMMI is not just for software development.
    • CMMI helps software and services organizations in a variety of industries to align meaningful process improvement with business and engineering goals for cost, schedule, productivity, quality and customer satisfaction.
  • CMMI offers three constellations
    • CMMI for Acquisition, CMMI for Development and CMMI for Services—that help to improve specific business needs, plus the People Capability Maturity Model (People CMM) which uses process framework as a foundation to help organizations managing and developing their workforce to become an employer of choice. Across these three constellations and the People CMM, CMMI delivers measurable results for organizations of all sizes in a variety of industries, […]
