Review & hand off / Editable XLSX

Interior design project timeline template

A useful timeline explains what must happen before the next activity can start. It is more than a colored sequence of dates: every review gate needs an output, an owner, and enough information for a decision.

Illustrative teaching extension of The Window Room. Pending review; not a client record, supplier quote, site survey, or construction-ready document.

What each field records

Phase
Name a phase or work package.
Output
State what must exist at the end.
Owner
Assign a real person or role when agreed.
Planned start
Enter a project-specific date; example intentionally blank.
Planned finish
Allow time for review rather than assuming instant approval.
Depends on
Name the prerequisite output or decision.
Review milestone
Describe the decision that allows progress.
Status
Record an actual state, not a guessed completion percentage.

How to use this template

The worked example shows sequence, not a promised duration. Enter dates only after confirming scope, decision availability, and supplier information. Keep dependencies understandable rather than hiding them in an unsupported automatic scheduler. When a prerequisite changes, review affected dates with their owners and preserve the reason for the revision.

  1. List phase outputs before adding dates.
  2. Name dependencies and the people responsible for reviews.
  3. Revise future dates when a prerequisite changes and record the reason.

Respond to a missing decision, not just a late task

The workbook is a dependency planner, not an automatic scheduler. Write what must be available for the next review, then assign dates using your actual scope and participants. A supplied lead time should retain its source and confirmation date in your project records.

If a prerequisite moves, review dependent activities explicitly. Do not shift dates by an arbitrary standard duration or mark the dependency complete to make the plan look on time.

Review before use

  • Do not copy durations from another project without checking scope.
  • A planned review date is not approval.
  • Do not let an outdated supplier lead time become an invisible schedule assumption.

Units, source information, and US use

The worked example keeps its original nominal metric dimensions. For a US project, choose and label a primary imperial or metric convention, distinguish item counts from areas, and document any display conversion and rounding. Never relabel metric values as imperial or treat conversion as site verification.
