The first ninety days as a manager
What to do, and what to stop doing, when you move from doing the work to leading the people who do it.
Your job changed more than your title
New managers usually keep doing the work that got them promoted, just with more meetings. The shift is from producing output to producing conditions: clarity, priorities, trust, and feedback.
A useful test at the end of each week: what did my team do differently because of something I did?
Hold one-on-ones that are theirs
The one-on-one belongs to the report, not the manager. Open with "What's most useful to talk about?" and resist turning it into a status update. Status can be written down; trust cannot.
Delegate outcomes, not tasks
Describe what done looks like, why it matters, and the constraints, then let the person decide how. Delegating tasks keeps you as the bottleneck; delegating outcomes grows people.
Get a baseline
Take a manager effectiveness self-assessment in your first month, and again at ninety days. The point is not the score but the comparison: it shows you which habits actually moved.
Put it into practice
Your AI coach can turn this into a goal with milestones and check in with you weekly.
