reasons for replan
Reasons for Replan
  • Significantly behind schedule
  • Behind on earned value: 29% of labor & dollars spent, but plan only 24% complete
  • Planned opportunity (scheduled in SEMP) to revisit plan approach, priorities, tasks, personnel, dictionary definitions, etc.
  • We also need to improve how we are managing this project
    • Schedule and budget are tools in accomplishing the project

Budget

Reduction in replan labor largely due to removing 1230h of students

next steps
Next Steps
  • Complete Replan with Team’s input
    • Determine how to proceed with System Architecture
    • New & revised WBS dictionary definitions
    • Improved management strategies
    • More focused team
    • Redo team meeting goals
  • Complete the following items in May:
    • SCRD & SRD v2
    • FRD v0 & Science Instruments FRD v1
    • Performance budgets summary
    • Trade Studies
    • Define Candidate Subsystems

+ Remember to do work scope planning sheets for new tasks
