Unit Availability (resource-timephased field)

Data Type    Percentage/Number (percentage/number field: A type of field whose content is a value that can be expressed as either a percentage or a decimal number. For example, in the Assignment Units field, one full-time assigned resource can be expressed as 100% or as 1.00.)

Entry Type    Calculated (calculated field: A field in which the value is determined by Project based on information in other fields. Project may recalculate the value automatically or when you specify, depending on your choice of calculation settings.)

Description    The Unit Availability field contains the percentage or number of maximum units (maximum units: The maximum percentage or number of units that a resource is available to be scheduled for any tasks. The maximum units value indicates the highest capacity at which the resource is available for work; the default value is 100 percent.) that a work resource (work resource: People and equipment resources that perform work to accomplish a task. Work resources consume time [hours or days] to accomplish tasks.) is available to accomplish on any tasks (task: An activity that has a beginning and an end. Project plans are made up of tasks.) during any selected time period, as distributed over time. This field also shows a timephased (timephased: Task, resource, or assignment information that is distributed over time. You can review timephased information in any available time period in the fields on the right side of the Task Usage and Resource Usage views.) representation for any changes in unit availability (unit availability: Amount of time, expressed as a percentage or a decimal number, that a resource can be scheduled for assigned work. It refers to the availability of a resource; for example, a resource may be available 50%, 100%, or 300% of full time.) for different time periods, as established in the Resource Availability table (table: A set of columns that shows specific information about tasks, resources, and assignments in a sheet view.) of the Resource Information dialog box.

How Calculated    The units you have set in the Resource Availability table of the Resource Information dialog box are reflected in the Unit Availability field, as distributed over the selected time period.

Best Uses    Add the Unit Availability field to the timephased portion of the Resource Usage view (view: The combination of one or more views [Gantt Chart, Resource Sheet, and so on] and if applicable, a table and a filter. Use views to work with information in a variety of formats. There are three types of views: Charts or graphs, Sheets, and Forms.) when you want to display the maximum capacity at which a resource is available to work on tasks during the selected time period. Also use this field to show changes in unit availability for different time periods, as established in the Resource Availability table of the Resource Information dialog box.

Example    You have planned for four painters to work on your project in March and April, six painters in May through August, and two painters in September and October. In the Resource Availability table of the Resource Information dialog box, you have reflected these dates with units of 400 percent, 600 percent, and 200 percent. Add the Unit Availability field to the Resource Usage view so you can see the changes in painter availability throughout the months. You can also see their availability by day or by week by changing the timescale (timescale: The time period indicator at the top of the Gantt views, the Resource Graph view, the Task Usage view, and the Resource Usage view. You can customize it to show up to three tiers that can display various time units: top, middle, and bottom.).

Remarks    In conjunction with the Unit Availability field in the timephased portion of the view, add the Max Units (maximum units) field to the sheet (sheet: A spreadsheet-like representation [in rows and columns] of task or resource information. Each row specifies an individual task or resource. Each column [field] specifies a type of information, such as start dates or standard rates.) portion of the Resource Usage view to see the unit availability for a resource for the current period.
