- status of current projects and resources that I manage (I am a manager myself)
- priorities and direction changes
- help needed, in any kind: escalations, resources, etc
From time to time, about every 3 months:
- feedback and intermediate performance review
- work plan updates
- strategy updates
Your 1 on 1 could be so much more: your career growth, situations you want help with, feedback and ideas for them, things you want coaching on, any issues they should know about (like say a sick/dying family member), etc
The last time we spent 15 minutes to discuss my idea of re-engineering the technical platform I own; my manager does not have the deep technical knowledge to understand the details and implications of the change, but I need his support to make it happen (to convince others, to allocate resource, etc) so I had to explain and convince him it is the right thing to do. The discussion was based on the 10 slides with diagrams that I sent a week before.
