Project tasks

Project tasks are the units of work that make up a project.

The size and number of tasks that comprise a project depends on the level of detail you want. For example:
  • Part of a task requires a specific skill.
  • Other activities in the task do not require the specific skill.
Break down that task further.

Bottom-up Tasking

Bottom-up (tactical) tasking means that you plan small, individual units of work that are required, then build a project up to include larger phases. Take this approach when you know what individual tasks are required to be accomplished and you are more flexible about overall project duration and estimated cost. Use this approach to see how much a project costs and how long it takes if you include every task. Project management supports tactical tasking by using rollup calculations on several project fields, such as project duration, so that the project adjusts to the tasks it contains. It is the recommended approach for the Project Management application.

Top-down Tasking

Top-down (strategic) tasking means that you plan high-level tasks first, then break down the work into smaller units. Take this approach when you want to build a project with fixed or inflexible time and budgetary constraints and well-defined phases. Establish well-defined milestones and dependencies between tasks that you consider from the beginning. Gradually add smaller tasks to the project later. This approach avoids including all possible tasks in a project and stays flexible with what tasks are included.
Note: When you use this method, the Project Management application still rolls up several values, such as task duration. Creating a task with a longer duration than the project, expands to cover the entire duration of the task, and defeats the purpose of using this approach. Values are not rolled down from parent tasks, nor are there any restrictions on creating child tasks that are longer than specified duration of the parent.
