The checklists are prioritized lists of all the tasks that you need to carry out. They list everything that you have to do, with the most important tasks at the top of the list, and the least important tasks at the bottom.
Mark the importance of the task next to it, with a priority from A (very important) to F (unimportant). Redraft the list into this order of importance. Then carry out the jobs at the top of the list first. These are the most important, most beneficial tasks to complete. You can also use software-based approaches to manage your checklist. You can often access these from anywhere, and they can often be synced with your Smartphone or PDA.
Run through these checklists allocating priorities from A (very important, or very urgent) to F (unimportant, or not at all urgent). If too many tasks have a high priority, run through the list again and demote the less important ones. Once you have done this, rewrite the list in priority order.
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.
