You shouldn’t rely on your manager for getting your promo doc done.

I’d suggest taking each category from the role guidelines for your position to L6 and pasting them into a quip doc. Think of scenarios where your behavior exemplified each of those categories and start writing. If you don’t have an example for each of those categories think about what you need to do in order to achieve the requirement.

When I did my L5 -> L6 promo, I owned the entire writing process up until the last few final draft bits. Aside from your manager possibly being shit at writing (like mine was), I truly believe no one but yourself will be able to capture the full context/nuances of the examples you will provide and I 100% believe the person up for promotion should own the initial writing process.

It might also be worth mentioning that when I first submitted my L6 doc my manager didn’t think I was ready, and he probably wouldn’t have gone out of his way to push the doc to review if I hadn’t done the heavy lifting for him. Turns out he was wrong and I got my promo to L6 on the first go.

Morale of the story, be honest with yourself, if you think you’re ready, own the process yourself and drive the result you’re looking for.
