As a manager, you need the flexibility to make split-second decisions, day in and day out. Tracking advancement on various projects, making sure the team members have made progress in delivering on their tasks, deciding whether to pursue a business opportunity or not, planning the strategy and priorities for the next year or month, when to host the next team meeting, brainstorm or outing, and everything else in between. Although some routine choices run up against are direct and straightforward, most situations on the job will require you to lean heavily on your knowledge, your analytical skills or experiences to resolve them.
