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-Do Lists can help you get, and stay, on top of important projects and piles of tasks or decisions. For instance, imagine you’re heading a team that’s working on a project. There are so many tasks to do, and so many people doing them, that staying on top of it all seems overwhelming.
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.
Task checklist have each step written in details which need to be followed in chronological order. While To-do checklist include a list of personal things that need to be done one after the other or simultaneously over a fixed time period.
