Although using a paper checklist is an easy way to get started, software-based approaches can be more efficient in spite of the learning curve. These can remind you of events or tasks that will soon be overdue, they can also be synchronized with your phone or email, and they can be shared with others on your team, if you’re collaborating on a project.
Recently, The Art of Manliness provided an historical look at checklists, along with a detailed primer in deciding which lists will work for you, culled from the excellent, The Checklist Manifesto. You can implement the same routine in your daily work to help give you a greater shot at success.
All of us think, plan and work differently. A program that works well for a colleague might not work well for you simply because you learn and think in your own way. This is why it’s useful to research and try several different ways of compiling your checklist before deciding on a single system.
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.
