Turn Imagined Failure Reasons into Actions and Ownership

A premortem considers causes of failure before a project begins by imagining an unsuccessful outcome. Use it to identify overlooked work and scheduling risks.

Imagined causes are different from measured probabilities. Define research and preventive actions with owners and review dates.

Write Possible Failure Reasons Independently

For a delayed launch, consider missing copy, pending review, or untested operations. Atlassian’s premortem includes individual writing time. (Atlassian: Premortem)

Record concerns from actual experience before group discussion.

Choose Actions by Impact and Missing Evidence

Record impact and evidence needed for each concern. Avoid assigning unsupported probabilities to rank risks.

Specify an Action for Missing Copy

Identify the copy, author, and due date so unfinished work can be tracked.

Add Owners and Review Dates to the Plan

Add preventive actions to the work plan and track completion. Reconsider risks and actions as the project changes.

Update public schedules and intake information against actual readiness.
