A flexible model for simulation of software development process

A flexible model for simulation of software development process

1. software development process

   • defined as set of
     • activities
     • methods
     • practices
     • transformations
   • used to
     • develop and maintain
       • software
       • associated products

2. Personal Software Process

   • aims to improve
     • quality
     • productivity
       • for individual engineers
   • produces metrics
     • including
       • LOC per hour
       • defects per thousans LOC
       • % of time spent per phase of cycle
     • which can be used for simulation

3. simulation model

   • agent-based
     • one agent<->one programmer
       • using individual PSP data
         • which consists of
           • defects introduced during
             • planning
             • design
             • code
             • compile
             • test
             • refactor
           • defects removed during
             • planning
             • test
             • refactor
             • total
           • fix time during
             • planning
             • design
             • code
             • compile
             • test
             • refactor
           • LOC
             • developed
             • per hour
             • upper per hour
             • lower per hour
             • defects per
           • time spent in
             • planning
             • design
             • design review
     • run in individual threads
   • basic approach
     • simulate each individual
       • as part of a team
       • based on production metrics from PSP
     • combine individual results within team

4. player

   • acts as project leader
   • provides
     • tasks
     • team assignments
     • expected
       • LOC counts
       • time
   • decides
     • number of developers
     • PSP data for developers
