How To Read CPM Metrics
ES (Early Start)
Earliest day a task can start based on predecessors.
EF (Early Finish)
Earliest day a task can finish: ES + duration.
LS (Late Start)
Latest day a task can start without delaying project finish.
LF (Late Finish)
Latest day a task can finish without delaying project finish.
Float / Slack
Delay buffer: LS - ES. Zero means critical task.
Critical Path
Longest dependency chain with zero float; drives project duration.
Network Duration
Total project duration from CPM forward/backward pass.
Validation Errors
Dependency cycles or invalid references that block reliable CPM analysis.
