Project Background

• Space Systems Technologies Corporation (SSTC) is subcontracted by Scaled Composites to build a 7/8 scale model of Gauchito rocket

– Earned Value Management (EVM) will be used for project management

– Project duration is 11 weeks

– Work Breakdown Structure (WBS) consists of 15 tasks

3

Situation At First Project Review

• Project baselined with 11 weeks duration and 18 weeks of level of effort

• Budget at Completion (BAC) equals $143,530

EVM Metrics After 4 Weeks

• Earned Value analysis after 4 weeks reported the following:– BCWS = $66,770– ACWP = $68,210– BCWP = $62,450– SV = -$4,320 (project is $4,320 behind schedule)– CV = -$5,760 (project is $5,760 over budget)– SPI = 0.94– CPI = 0.92– EAC = $156,768 (EAC is 9% over BAC)– VAC = -$13,238– ETC = $88,558 (expected cost needed to complete all

remaining work)

• Project is one week behind schedule and over budget– Project EAC is still within acceptable range and not in trouble

Situation At Week Eight

• Scaled Composites decided to modify the project’s scope

– Drop the Test Launch Preparation deliverable (task #15)

– Request SSTC to replan the project

– SSTC to present new revamp edbaseline for approval

– SSTC to present EVM metrics of rebaseline project to present time

Rebaseline EVM Metrics After 8 Weeks

• Earned Value analysis after rebaseline and after 8 weeks reported the following:– BCWS = $84,695– ACWP = $84,695– BCWP = $84,695– SV = $0 (project on schedule)– CV = $0 (project is on budget)– SPI = 1.0– CPI = 1.0– EAC = $97,850 (EAC equals to BAC)– VAC = $0– ETC = $13,155 (expected cost needed to complete all

remaining work)

• Project is on schedule and on cost (doing very well)10

Conclusion

• At direction from Scaled Composites, project duration remains at 11 weeks– Last deliverable was removed– Project was rebaselined

• EVM after 8 weeks reports project is on schedule and on cost and is doing very well
