Use the Max. Units field in a resource view to indicate whether the work resource is full time or part time on this project, or whether multiples of this resource are consolidated into one. For example:

• If you want to indicate that all the person’s time is devoted to your project, type 100% in the Units field on the Resource Sheet view. If the person works 8-hour days, he or she will be overallocated if any combination of assignments exceeds 8 hours (100%) of the available workday.
• If you want to indicate that only a part of a person’s time is devoted to your project, type a number less than 100% in the Units field on the Resource Sheet view. If the person works 8-hour days and has 75% of his or her time devoted to your project, he or she will be overallocated if any combination of assignments equals more than 6 hours (75%) of the available workday.
• If you want to indicate that a resource group, such as three carpenters, will work on the project full time, type 300% in the Units field on the Resource Sheet view.
