A checklist is a simple tool used to ensure that tasks or items are completed or accounted for. It typically consists of a list of items, tasks, or steps that need to be checked off as they are completed. Checklists are commonly used in various fields, including aviation, healthcare, and project management, to enhance efficiency and reduce the risk of errors. Using a checklist can help individuals and teams stay organized and focused. By breaking down complex tasks into manageable steps, checklists make it easier to track progress and ensure nothing is overlooked. They can be created on paper or digitally, making them versatile for different situations.
