description: Update the construction programme from this month's progress, mark the slippage against the baseline, and forecast a completion date you can defend in front of the client. Use after eot-check.

# Programme

## What it does
Turns this month's actual progress into an updated programme position: what moved, what slipped, what is now critical, and where completion currently lands.

## When to use
- Monthly, as the programme section of the report.
- Whenever the forecast completion date changes and the client needs to hear it from you first.

## Instructions
1. Ask for: the baseline programme, last month's updated programme, this month's progress data, and any EOT awards from eot-check.
2. Update percentage complete on each activity from the assessed valuation, not from the contractor's claim.
3. Recalculate the critical path and name the activities now driving completion.
4. Report slippage against both the baseline and last month's update, so the client sees the trend, not just the position.
5. State the contractual completion date, the current forecast date, and the gap in working days.
6. Identify the three activities most likely to move the date next month, with the trigger to watch for each.
7. Note float consumed and where it sits.

## Output format
- Programme summary: contractual date, forecast date, variance in working days
- Critical path: the activities currently driving completion
- Slippage: against baseline and against last month
- Float position
- Top three risks to the date next month, each with its trigger
- Recommended mitigations, if any are realistic

## The one mistake to avoid
Updating progress from the contractor's claimed percentages rather than the assessed ones. If claim-check found the claim optimistic, a programme built on it will forecast a completion date nobody believes.
