part of the solution
People
Objective of improvements is
Increasing the Performance on time,
in budget, in quality
on-time
Directly influenced may be
people, processes, and
technology – therefore,
these are the dimensions to
act.

16. CMMI is a FRAMEWORK
• Not a Standard for developing products or
development processes
• Not a life cycle, nor a process, does not require
waterfall
• Not a prescription
• Is a description
• Does not require purchase of software or tools
• Mean for process Improvement not process
compliance
17. Why Maturity Models
• Benchmarking
• Improving
• Institutionalizing
• Good Practice catalogue

60. Configuration Management (CM)
Purpose
• Establish and maintain the integrity of
work products using configuration
identification, configuration control,
configuration status accounting, and
configuration audits.
61. Baseline SG1: Establish baselines of identified
work products
• A set of specifications or work products that has been formally reviewed and agreed

76. Agile Processes
• Realistic – defined with support of those who will be using
it, not ‘theoretical experts’
• Live – Revised basing on lesson learned from individual
project
• Flexible – can be tailored to team and project needs, should
allow creativity, not introduce artificial limits
• Learnable – Written using language understandable by
those who will be using it
• Supportive – must be perceived as helpful by those who
will be using it.
• Lean – limit the ‘waste’ in the processes. Remove all
activities that does not add value to final product.
• Owned - by those who per form work

• Flexible – can be tailored to team and project needs, should

• Owned - by those who per form work
78. Agile
• Culture of high trust
• Collaboration with customer
• Flexibility and ability to react
• Transparency
• Concentrates on learning – inspect & adapt
• Self organizing – delegating power to the team
• Working software
• Tools & techniques
• Implements ‘how’ of CMMI’s ‘what’.
• Supports CMMI, but do not cover all requirements
79. CMMI
• Organizational development and learning
• A model, not a cookbook
• Can be applied in any context and organizational
size (just a matter of interpretation)
• Is not in contradiction with Agile Philosophy and
techniques
• Wider coverage
• Focus on institutionalization of good practices
• Implement CMMI rather than applying it
