This project checklist is a document used to keep track of all of the tasks, deadlines, resources, and goals required to complete a project. Project managers, team leaders, and supervisors frequently use project management checklists to organize and track the progress of the various elements of a project. Project managers are often in charge of multiple employees, teams, deliverables, subtasks, and other responsibilities. A checklist allows project managers to keep track of all the people and tasks involved in the project at the same time. Projects can have many subtasks, making it difficult for some employees to know what to do first.
