Practice

Calculate a simple working duration

A task requires 24 hours of effort and one assigned contributor has 6 available hours per workday. Ignoring other constraints, how many workdays are required?

Schedule logic line

Turn work evidence into a reviewable forecast

  1. EstimateEffort + rangeSource, assumption, uncertainty, and refinement point.
  2. SequenceLogic networkPredecessors, successors, parallel paths, and blockers.
  3. CalendarCapacity + datesWorking time, availability, and fixed constraints.
  4. ForecastMilestones + rangeCurrent expectation while the baseline stays visible.
Forecast ruleWhen evidence is uncertain, disclose the range and next review instead of inventing precision.

Effort and range estimates become dates only after dependencies, calendars, capacity, and milestones are applied.
