10. 10 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

15. 15 Replan

16. 16 Budget Reduction in replan labor largely due to removing 1230h of students

17. 17 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
