Size the tasks appropriate to your intent. For example, if you want to maintain general oversight of an entire project, you might have 12 tasks (one for each of the 12 steps used in the 12-step project template). If you are managing a time-critical process, you can break down the tasks into more defined steps such as create design, review design, draft, proof blueprints, make prototype, and so on.
In some cases, when you plan your entire project at the beginning, you may find the original chart does not reflect the current state. In these cases, you should modify the chart with appropriate notation that explains the reason for the change.
