Mastering procedural processes and repetitive tasks with checklists allows you to focus on the larger goals at hand. It’s the minutiae of the workday that can be easily forgotten at the detriment of other important projects.
To use your checklist, simply work your way through it in order, dealing with the A priority tasks first, then the Bs, then the Cs, and so on. As you complete tasks, tick them off or strike them through.
Troubleshooting checklist include step by step instructions that need to be followed in case of emergencies like a fire breakout. While Coordination Checklist will help maintain coordination in situations where different departments or teams are required to collectively perform a task. However, the Discipline Checklist comprise guidelines following which will prevent taking wrong decisions.
But in you’re in an operational role, or if tasks are large or dependent on too many other people, then it may be better to focus on a longer-term checklist, and "chip away" at it day-by-day. Many people find it helpful to spend, say, 10 minutes at the end of the day, organizing tasks on their list for the next day.
