Your incident report is 10 pages. Nobody reads it.

The incident happened. You wrote a thorough post-mortem. 10 pages of timeline, root cause analysis, and recommendations. 

Nobody read it. Your team repeated the same mistake three months later. Length doesn’t equal thoroughness. A one-page report that gets read beats a 10-page report that collects dust. 

The scenario:

You want to create a post-incident report template that’s short enough to read and actionable enough to prevent repeats. 

The prompt:

You’re building a one-page incident report template.

Structure it in three sections:

  • What happened (timeline in 5 bullet points, max)

  • Why it happened (root cause, not blame)

  • What changes (specific actions, owners, deadlines)

Rules:

  • Total length: one page

  • No jargon the client wouldn’t understand

  • Every action item has a name and a date

  • Include a severity rating and business impact in one sentence

Create both an internal version and a client-facing version.
