Including Level-of-Effort Tasks in the Schedule
You must include all project management and technical tasks in the schedule. Some of these are level-of-effort (LOE) tasks, which are activities that are not easily measured in terms of discrete accomplishments. LOE tasks that should be listed in the project schedule include, but are not limited to:
As you schedule these LOE tasks, you must validate your estimates to ensure that you have included enough time. In doing this, you might find that you need additional time; if so, you must include it. If you do not, and the contract is a fixed-price contract, the cost will be higher in the end.
