Summary

Learn to plan deadlines using deliverables, required inputs, approval waits, realistic capacity, and early adjustments when delays affect subsequent work.

Include Work and Waiting Time in the Delivery Plan

A deadline plan includes required inputs and approvals as well as start and finish dates. Estimate both available working time and waits for other people.

When delays emerge, share remaining work and affected dates. Changed effort may require a revised scope or schedule.

Identify Work and Inputs from the Deliverable

For a service-page launch, list information decisions, assets, drafting, review, and publication. Identify work that can proceed and work awaiting approval.

Estimate from Previous Work and Available Time

Use comparable past work, adjusting for new conditions and revisions. Do not count a day of meetings and other duties as a full working day for the task.

For uncertain work, record the expected range and investigation needed rather than relying only on a fixed reserve percentage.

Identify Delay Impacts and Adjust the Plan

Track remaining outputs and awaited information. When a delay affects subsequent work, consider scope or launch-date changes.

Update public announcements and signup conditions if the release date changes, keeping internal and public plans consistent.
