What is a list that precisely describes all tasks and items in a project plan called?

In project management, a list that precisely describes all tasks and items in a project plan is referred to as specifications or "specs." Specifications serve as a detailed outline that includes the specific requirements, responsibilities, deadlines, and deliverables that need to be accomplished within the project. This level of detail ensures that all stakeholders have a clear understanding of the project's scope and the individual components that contribute to its success.

In contrast, a timeline is more focused on scheduling and illustrating when tasks should occur, while a blueprint refers to a visual or structural representation of a project, often used in design contexts. A task list, while it may include tasks to be completed, generally lacks the comprehensive detail and specifications necessary for thorough project planning.
