Regardless of what level of the organization you are being promoted to, you need to be onboarded. If there isn't a plan for that, create one yourself or with the help of your HR organization. Here are a few other tips:
- A manager's focus is on the team he or she manages. The job is to build the team. In contrast, a leader's focus is on the future (strategy) of the organization. The job is to build the capacity to thrive in the future. These are very different jobs and moving between them can be a challenge.
- Identify people who have a job similar to the one you are promoted into. Figure out who the best ones are, and observe what they do and say. Figure out who the weakest are, and observe the same.
- Seek first to collaborate. Competition usually creates a battle and someone will lose.
- Do research on the goals of the organization and make sure you understand the boundaries of those goals at your new level. Know the playing field as quickly as possible.
- Invest in leadership opportunities and learning. There are so many wonderful programs online. Consider joining a peer group outside of your organization for additional perspectives.
- If you end up managing people who used to be your peers, check out the wonderful book and guide by Kevin Eikenberry titled Bud to Boss.
