• The Trilinos Three Phase Promotional Lifecycle
  Model
• Review all phases
• Discussion
• How we can implement this model
• Feedback
• General SQA questions/discussion

3
The Trilinos Three Phase Promotional Lifecycle
Model

• The three phases
• Research
• Production Growth
• Production Maintenance
• Other important components of the model
• First Promotional Event
• Releasable Status
• Second Promotional Event
• Maintenance Ready Status

4
The Trilinos Three Phase Promotional Lifecycle
Model

• Research Phase
• First Promotional Event
• Production Growth Phase
• Releasable Status
• Second Promotional Event
• Production Maintenance Phase
• Maintenance Ready Status

5
The Trilinos Three Phase Promotional Lifecycle
Model

• Research Phase
• Primary goal is research
• Software is potentially incidental to research
• Releases for select internal customers only
• Should not be treated as production quality
• Few required practices
• Default level of formality is low

6
The Trilinos Three Phase Promotional Lifecycle
Model

• Sample Research Phase requirements
• Research proposal (project plan)
• Backup
• CVS
• V V
• Peer reviewed publications
• Status reports
• Design artifacts
• Lab notebook
• Mail list archives

7
The Trilinos Three Phase Promotional Lifecycle
Model

• First Promotional Event
• Promotion from research to production
• Takes place before first release
• Involves
• Risk assessment
• Gap analysis
• Promotion decision

8
The Trilinos Three Phase Promotional Lifecycle
Model

• Production Growth Phase
• Goal make package releasable
• Suitable for highly skilled users
• Increased
• Number of practices
• Level of formality
• Maintain flexible development environment
• Spiral (cyclic) - Agile methods encouraged
• Default level of formality is medium

9
The Trilinos Three Phase Promotional Lifecycle
Model

• Production Growth Phase requirements
• Essential ASC SQE practices performed at
  appropriate level
• Dev Guide Part 2, version 2.0
• Gap analysis from first promotional event
• Artifacts from practices
• Naturally produced by completing required
  practices
• Status and management reports
• Software metrics
• Process improvement

10
Releasable Status

• Releasable status is reached when the required
  level of practices and processes have been met
  for phase 2
• Artifacts are reviewed by the Trilinos Project
  Leader (or a designee)

11
The Trilinos Three Phase Promotional Lifecycle
Model

• Second Promotional Event
• Promotion from growth to maintenance
• Can take place when
• Code is naturally entering a maintenance phase
• Requested by a customer, stakeholder, or project
  leader
• Development team wants to transfer support duties
  to another group
• Project is starting to wind down
• Involves
• Risk assessment
• Gap analysis
• Promotion decision

12
The Trilinos Three Phase Promotional Lifecycle
Model

• Production Maintenance Phase
• Goal robust software for typical end users
• Requirements and software are stable
• Waterfall or Unified Process lifecycle model
• Formal internal documentation (UML suggested)
• Default level of formality is high

13
The Trilinos Three Phase Promotional Lifecycle
Model

• Maintenance Ready Status
• Package has implemented the required level of
  practices and processes for phase 3
• Package
• Supports all formal missions
• Supports required platforms
• Is user-proof
• Provides user support (conditional on continued
  funding)
• Training
• Documentation
• Bug reporting
• Help desk
• Will not be included in future releases if
  process stalls before reaching maintenance ready
  status

  the coming year
