A war list is an informal term for a concise list of priority items used when a project is starting to spiral slightly out of control. It is most commonly employed by a task force.
Explanation:
A War List, often just a single-sheet on an Excel file, might initially start as a very long list of all the things that need attention on a project. However, it is the project manager’s responsibility to organise and prioritise this list, transforming it into a structured “order of march.”
The War List differs from a regular task list because it is typically managed manually, frequently updated by the project manager themselves in a spreadsheet. It serves as their personal working document to track and manage tasks. While other team members are not expected to update this list directly, it remains accessible as a constant, living reference for the team.
