When you are first appointed as a manager many things will come your way. New impressions, new relations, new responsibilities and new issues that you need to ponder and find solutions for. It makes a huge difference if you were already in the company and got promoted or that you were hired from outside. Both have their pros and cons. When you were internal you’ll have an easier time negotiating the company politics, when you come from outside it will be easier to be seen as a manager and not as “Joe who got a new position”. Much more can be said about this but my main point, as usual, is that you need goal clarity. The assignment needs to be crystal clear for you as manager, in order to be able to effectively lead your group.
The other important immediate issue is to find out what the social composition of the department or group is. Who hangs out with who, who has been here forever, who is the smartest person in the group, who has most experience. You need to know your resources.
Next you’ll have to find an effective way to communicate with the people; do they need meetings, are memos a thing, will emails be effective, is there a reporting system that helps the flow of work.
All great things to think about. The Fast company has a nice article about someone starting as a manager and the lessons learned in their first 30 days.
For me the goal clarity, getting to know the resources and finding an effective way to communicate would be the first focal points. You can read more about this in my book where I highlight the importance of many other points also.
Let me know what you struggled with in your first days as a manager. We’ll follow up over time with a summary.
