Estimate parallel work duration

After one shared approval, a 3-day layout task and a 5-day translation task can run fully in parallel. Ignoring other constraints, how many workdays do those parallel tasks add before both are complete?

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.
