As a manager, part of your job will be the cultivation of such playbooks: how to run a team meeting, how to close a new hire, how to complete a project on time and on budget. If you find yourself doing a similar thing over and over again, chances are good that it can be codified into an instruction manual or checklist that can make the task go smoother in the future. Another bonus of doing this: you can then pass the playbook to others to learn and execute.
