Your 30 first days as a manager

Ensure that the link between your team’s work and the organization’s success is understood.  Develop a clear understanding of how your team contributes to the mission/finances/results of your organization.  Make sure your team understands it as well

Set annual performance goals for yourself (if not done yet) and for your team.  Do this even if your organization doesn’t formalize this process.

Set tactical plans for the next 90 days that match your performance goals.  Keep linking your individual and team goals back to the organization’s direction and strategic plan.
