Planning / Targets & deadlines
A target is a date you would like to achieve. A hard deadline records an external commitment. The forecast shows when the recorded work can finish under the current constraints.
Understand the model ↓See the worked example →Projects can record a target, a hard deadline and the reason for that commitment. Date-only targets and deadlines mean the end of that day. The forecast is calculated separately; entering a deadline does not create extra working time.
Headroom compares the forecast finish with the hard deadline in calendar hours. A forecast beyond that commitment is threatened; an already-missed commitment and an unknown completion are distinct situations. A missed target is also identified separately.
These are comparisons based on the recorded plan, not a prediction of every future disruption. Can You Just does not automatically change the commitment to make the forecast look comfortable.
An urgent fix may be the right thing to do. The useful question is what that choice means for the existing promise. Review estimates, priorities, capacity or the commitment with the people involved.
What If planning lets you inspect a proposal before applying it. A higher priority still cannot override a prerequisite or someone’s unavailable time.
A FICTIONAL SCHEDULING STORY
Alice’s two hours of release checks fit from 15:00 to the hard deadline at 17:00.
A committed urgent fix reserves her first hour, from 15:00 to 16:00.
Project completion: Fri 17:00
Hard deadline: Fri 17:00Tight headroom
Project completion: Fri 18:00
Hard deadline: Fri 17:00Hard deadline threatened
Example assumptions. Friday 23 October 2026. Alice works until 18:00. No priorities or dependencies are changed to hide the capacity shortfall.
THE CONSEQUENCE
The deadline creates no extra capacity. Release checks now need 16:00–18:00.
THE REVISED PLAN
The hard deadline remains Friday 17:00. Completion is forecast for 18:00: one calendar hour beyond the commitment.
