There are many time management software programs available. At a simple level, you can use MSWord or MSExcel to manage your lists. Some versions of Microsoft Outlook, and other email services such as Gmail, have task lists as standard features. Remember the Milk is another popular online task management tool that will sync with your smartphone, PDA, or email account. It can even show you where your tasks are on a map.
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.
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.
To-Do Lists are particularly useful when you have a small number of tasks that you need to complete. However, they can become cumbersome when you have too many items on them, or when you need to progress multiple projects. At this stage, it’s worth starting to use Action Programs, which are designed to manage more complex situations reliably.
