Post-mortems

Hey all,

Doing my first post-mortem for an app and at a bit of a loss on how to format/organize/write it.

I made a survey for all stakeholders that goes into details on what went well, what didn't, and what to improve. So the content is there, and I can follow up if I need more details.

How do you prefer to organize and write a post-mortem, especially one that is intended for leadership? And how much detail do you go into? How long does it take you to put together?

I know it's supposed to be a blameless document and its intention is to use the info for other launches, but would appreciate knowing everyone's process.

Thanks
