Accountable owner roles
This checklist is a project-management framework, not legal, regulatory, engineering or certification advice. Exact requirements vary by location, authority, facility design, operating model and project objectives. Validate applicability with qualified local professionals and the relevant authorities. Completing the checklist does not guarantee approval, certification, uptime or regulatory compliance.
How to use this tracker
Each row is an executable work package. Assign a named individual against the accountable role, enter planned start and end dates, follow the predecessor task IDs, and mark a task complete only when its completion criterion is met and supporting evidence has been reviewed.
The owner column deliberately contains the accountable role, not a person’s name, so the tracker stays reusable across organisations. Add a Named_Ownercolumn — or use the local “Named owner” field on each task below — in your working copy.
Using it in Excel
- Import the file as UTF-8.
- Convert the imported range into an Excel Table.
- Freeze the header row.
- Use ISO dates in YYYY-MM-DD format.
- Add data-validation lists for Status and Applicability.
- Filter Critical tasks and blocked project gates during every project review.
- Add a Named_Owner column in the working copy.
- Record the accepting authority in Notes for Accepted Risk.
- Preserve stable Task IDs when customising the tracker.
- Do not mark a task complete until its evidence has been reviewed.
Status legend
- Not Started
- No work has begun on this task yet.
- In Progress
- Work is underway but the completion criterion is not yet met.
- Complete
- The completion criterion has been met and supporting evidence has been reviewed. Do not mark a task Complete only because the activity occurred.
- Blocked
- The task cannot proceed. Record the blocker in Notes.
- Not Applicable
- Record the reason and the approving authority in Notes.
- Accepted Risk
- Record the accepting authority, the interim control and the review date in Notes.
Applicability legend
- Required
- This task applies to the project as scoped.
- Conditional
- Applicability depends on site, authority, technology, or scope decisions not yet made.
- Not Applicable
- Confirmed out of scope for this project — record the reason in Notes.
- To be assessed
- Applicability has not yet been evaluated for this project.
Priority (Critical, High, Medium, Low) and Applicability are always shown as text, never by colour alone.
