When many subteams within an overall project team each have individual

responsibilities, the outline can be a little unwieldy because it doesn't visually

separate activities according to functional lines.

A combination tree diagram and outline WBS.

The tree diagram WBS (see the following figure) does a magnificent job of separating functional

activities. Its major shortcoming is that to convey high levels of task detail, the tree diagram would

be huge. It might get too big for a single piece of paper or single computer screen, and hence

would have to be plotted on a large wall chart. Even then, all the tasks and subtasks of all the

players in all of the functional departments would necessitate constructing a large and complex

chart indeed.

Such a chart is actually a hybrid of the detailed outline and the tree diagram. Nevertheless, many

project managers have resorted to this technique. By constructing both an outline and tree

diagram WBS and then combining the two, however large and unwieldy the combination gets, you

end up with a single document that assures the totality of the entire project.

Here's an example of a segment of an outline and tree outline WBS combined.
