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
