What must be defined to understand the duration of project tasks?

To accurately understand the duration of project tasks, it is essential to define the length of time required to complete each task. This involves estimating how long each specific task will take to achieve its goals within the overall project timeline. Accurately determining task duration allows project managers to schedule the project effectively, allocate resources accordingly, and set realistic deadlines.

While the other factors such as resources, sequence, dependencies, and costs are important for project management, they do not directly measure the time commitment necessary for each task. Understanding task duration is a foundational component in project planning, as it directly influences the overall timeline and efficiency of the project. If the duration of tasks is not defined, it becomes challenging to gauge project progress, manage expectations, and ensure timely project completion.
