The movement generated by the agile methods can bring a virtuous force to the evolution of software engineering. Excellence comes with a constant care with the quality of the product delivered, though controlled and sustained development processes, allied to a good capacity for adaption, innovation and focus on people. This presentation provides a method that will supply criteria and pre-requisites for a methodology adapted to the organization's needs to combine CMMI and Agile methods.

• IT systems are much more software dependent than before and for that
software project management presents itself as a crucial discipline.

5. Objectives
• More recently a series of methodologies for software development emerged
which put the emphasis on:
• the capacity for a process to absorb changes throughout the project
• the human side, promoting self-directed teams, a trustworthy and close contact with
the customer.
• This presentation aims to show how the combination of software development
methodologies, more and less agile can be synergetic.
• This combination will be instantiated on a strategy that will supply criteria and
pre-requisites for a methodology adapted to the specific organization needs.

6. All models are wrong but all of them are useful
• CMMI – Capability Maturity Model Integration – “The foundations for
organizational excellence”
• TPS/PSP – Team Software Process – “The foundations for personal and team
excellence”
• PMBOK – Project Management Body of Knowledge – “The suite for project
management”
• Scrum – “The light weight methodology for project management”
• XP – Extreme Programming – “Extreme Engineering?”

9. Software Excellence
• Software Development Management must promote:
• Systemic Approach – organization, project and engineering
• Efficient – cost of quality always present
• Quality – on product and services delivered
• Sustained Excellence – Controlled, tailored, adaptive and innovative processes

10. The project strategy method
• Phase 1 – The organization setup
• CMMI process elements and generic practices
• Phase 2 – The project additions
• PMBOK
• Phase 3 – Agile patterns detection
• Phase 4
• TSP/PSP taylored (the favourite)
• Or Agile pumped up

11. Phase 3 – Agile pattern detection
• Initial premise: existence of uncompleted, unknown or volatile requirements
• Pattern conjunction
• The team has technical maturity
• The team is prepared for a informal culture
• The project or project phase doesn’t have a big dimension
• There is a trust relationship with the customer
• The customer, or representative, has physical and temporal availability
• The project team is not located in distinct places
• The customer doesn’t require exhaustive documentation

12. Conclusions
• Always apply the best principles regardless of the projects
• Iterations, incremental evolution
• team management involvement: motivation and commitment, empowerment and
coaching
• focus on the customer: relationship, trustable and aligned
• Search for agile patterns
• The agile movement reminds us of the people factor
• Let’s us not forget the rest now
