Complete firstCalendar and priorities
Available time and fixed appointments are known; tasks have identifiable priorities.
Without priorities, overload is simply copied into the calendar.

Materials
Calendar or daily grid, task list, duration estimates and room for replanning.
People / roles
Person planning; affected teammates for shared commitments.
Pre-read
Collect working hours, fixed appointments, tasks and deadlines; include breaks and transitions as real time.
Time needed
10–20 minutes daily planning; brief adjustments during the day
Setup
Open a daily grid with start and end times; enter fixed appointments first and leave room for revisions.

Core question
The one question this method answers
When will I work on which outcome within my actual capacity?
04
Flow
Phases with goal, actions, output and pitfall
Time blocking translates priorities into concrete calendar intervals. Fixed appointments, focused work, reactive tasks and rest share the same limited capacity; the plan is deliberately revised when circumstances change.

Fictional example
Time blocking translates priorities into concrete calendar intervals. Fixed appointments, focused work, reactive tasks and rest share the same limited capacity; the plan is deliberately revised when circumstances change.
Time boundary
Which working hours, breaks and fixed appointments bound the plan?
Fictional: 09:00–13:00; meeting 10:30–11:00, break 11:00–11:15.
Time blocks
Record start, end and outcome for each block including buffer.
09:00–10:15 proposal; 10:15–10:30 buffer; 10:30–11:00 meeting; 11:00–11:15 break; 11:15–12:00 support; 12:00–12:45 tests; 12:45–13:00 buffer/review.
Replanning
What changes and which work is deliberately reconsidered as a result?
Support takes until 12:15. Tests are limited to 30 minutes; remaining cases receive a new block tomorrow at 09:00.
Planning learning
Which variance improves the next estimate or capacity assumption?
Support took 60 rather than 45 minutes: reserve 60 minutes on launch days in future.

Goal
Available time windows
Inputs for this step
- Calendar
- Working hours
Actions
- Enter work start, work end, fixed appointments and breaks in the time grid.
- Identify free intervals and required transitions.
Output
Available time windows
Is available time calculated without double booking?
Quality check
Is available time calculated without double booking?
Pitfall
A whole workday is treated as free despite appointments. Block fixed commitments first and plan only remaining intervals.
Timing: 3–5 minutes

Assign work blocks
Assign work blocks
Goal
Feasible block schedule
Inputs for this step
- Time windows
- Prioritised tasks
Actions
- Place important outcomes with realistic durations in suitable free intervals.
- Batch similar small tasks; explicitly reserve reactive work and buffer.
Output
Feasible block schedule
Does each block have a purpose and fit its interval?
Quality check
Does each block have a purpose and fit its interval?
Pitfall
Blocks touch with no transition time. Insert transitions and buffer and remove overflow.
Timing: 5–10 minutes

Execute and replan
Execute and replan
Goal
Updated daily plan
Inputs for this step
- Block schedule
- Actual events
Actions
- Work on the agreed outcome in the current block; capture new demands and replan when circumstances genuinely change.
- Deferred tasks receive a new date or a deliberate cancellation.
Output
Updated daily plan
Are changes visible rather than extra parallel commitments?
Quality check
Are changes visible rather than extra parallel commitments?
Pitfall
A delay silently shifts the whole day. Recalculate remaining capacity and decide how to handle overflow.
Timing: 2–5 minutes
- 4
Compare plan and reality
Compare plan and reality
Goal
Improved planning assumptions
Inputs for this step
- Planned and actual time
- Outcome view
Actions
- Briefly review duration variance, interruptions and achieved outcomes at day’s end.
- Address recurring bottlenecks with smaller blocks, realistic estimates or more reactive time.
Output
Improved planning assumptions
Does the observation change the next plan?
Quality check
Does the observation change the next plan?
Pitfall
Schedule variance is treated as personal failure. Correct the assumption about duration or availability.
Timing: 3–5 minutes

Stop criteria
When to pause, resolve prerequisites, or choose another approach
If tasks exceed capacity, remove, defer or negotiate work; do not treat breaks and buffer as an invisible reserve.
