A checklist is a simple and organized tool used to track and manage tasks, items, or steps in a systematic manner. It typically consists of a list of items or actions that need to be completed or verified, with checkboxes or spaces to mark off each item as it is accomplished. Checklists are employed in various contexts, including project management, quality control, travel planning, and daily routines, to ensure that nothing is overlooked and that tasks are completed efficiently and accurately. They provide a visual representation of progress and help individuals or teams stay organized and accountable. Checklists are versatile, easy to create, and invaluable for enhancing productivity and reducing errors in various tasks and activities.
