A checklist is a simple tool used to organize tasks or items that need to be completed or verified. It typically consists of a list of items, each accompanied by a checkbox that can be marked when the item is completed. Checklists are commonly used in various fields, including project management, education, and healthcare, to ensure that important steps are not overlooked. Using a checklist can enhance productivity and efficiency by providing a clear outline of what needs to be done. They help individuals and teams stay focused and organized, reducing the likelihood of errors. Checklists can be created on paper or digitally, making them versatile for different preferences and situations.
