1. Inception


Engineering and

production Stages

4. Transition


2. Elaboration





Software Development Process

  • Well defined separation between research and development activities and production activities
  • Overemphasis on research and development
  • Overemphasis on production
modern software development process support
Modern Software Development Process Support :
  • Evolution of the Plan, requirement and architecture
  • Risk management and objective measures
  • Evolution of System capabilities
life cycle phases
Life Cycle Phases :
  • Engineering stage - driven by less predictable but smaller teams doing design and synthesis activities
  • Production Stage - driven by more predictable but larger teams doing construction, test, and deployment activities.

inception phase
Inception Phase :

Primary Objectives

  • Establishing the project software scope and boundary conditions
  • Clear Understanding of what should be there or what should not?
  • Demonstrating at least one candidate architecture
  • Estimating the cost and schedule for entire project
  • Estimating potential risks
Essential Activities
  • Formulating Scope of the project
  • Synthesizing the architecture
  • Planning and preparing a business case
primary evaluation criteria
PrimaryEvaluation Criteria
  • Satisfaction of all stakeholder!!
  • Are requirements understood by critical use cases ??
  • Are the cost and schedule estimates credible??
  • Do the depth and breadth of an architecture prototype demonstrate the preceding criteria??
  • Resource management is there or not??
elaboration phase
  • Most Critical Phase!!
  • Executable architecture prototype is built
  • Make a vision
  • Establishing a configuration managed snapshot
  • Base lining a fidelity plan for next phase
  • Cost Vs Time graph must work smoothly
primary objectives
Primary Objectives
  • Base lining the architecture as rapidly as practical.
  • Base lining the vision
  • Base lining a high-fidelity plan for the construction phase
  • Demonstrating that the baseline architecture will support the vision at a reasonable cost in reasonable time
essential activities
  • Elaborating the vision: Understanding use cases that do planning decisions
  • Elaborating the process and infrastructure: evaluation of milestones is done i.e. what percent we have reached??
  • Elaborating the structure and selected components
primary evaluation criteria1
Primary Evaluation Criteria
  • Is the vision stable??
  • Is the architecture stable??
  • Address the major risks that can occur
  • Do all stakeholders agree on current vision
construction phase
Construction Phase
  • During this phase, all remaining components and application features are integrated into the application and all features are thoroughly tested.
  • Newly developed software is integrated when required.
  • Managing resources and controlling operation to optimize costs, schedules and quality is the emphasis of the construction phase which represents production stage.
primary objectives1
Primary Objectives
  • Minimizing developing cost by optimizing resources
  • Avoid unnecessary scraps and rework
  • Achieving adequate quality as rapidly as possible.
  • Achieving useful versions (alpha ,beta, and other tests releases).
essential activities1
Essential Activities
  • Resource Management, control and process optimization
  • Assessment of Product releases
  • Complete component development and testing
primary evaluation criteria2
Primary Evaluation Criteria
  • Is this product baseline mature enough to be deployed in the user community?
  • Is this product baseline stable enough to be deployed in the user community?
  • Are the stakeholders ready for the transition to the user community?
transition phase
Transition Phase
  • This phase is entered when a baseline is mature enough to be deployed in the end user domain.
  • This phase includes ::
  • Beta testing to validate the new system
  • Conversion of the operational databases
  • Training of users
primary objectives2
Primary Objectives
  • Achieving user self-supportability.
  • Achieving stake holders concurrence that deployment baselines are complete and consistent with the evaluation criteria.
  • Achieving Final product baselines as rapidly and cost-effectively
essential activities2
Essential Activities
  • Synchronization and integration of current construction increment into consistent deployment baselines.
  • Assessment of deployment baselines against the complete vision
  • Acceptance criteria in the requirement set
evaluation criteria
Evaluation Criteria
  • Is the user satisfied?
  • Are actual resource expenditures versus Planned expenditures acceptable?
