Reports → Demand vs Capacity
You can use the Demand vs Capacity tab to see relationships between resource demand and resource capacity for a selected item in your organization's portfolio. The left side of the Demand vs Capacity tab lists the selected item and its attributes. The right side of the Demand vs Capacity tab displays the demand and capacity values for the selected time period. Each time period contains the total demand and capacity values for the item and may contain individual columns for selected resource roles or the total values for each time frame. The lower pane aggregates totals from the portfolio, showing total demand and capacity, and the variance between.
One of the key benefits to using the Demand vs Capacity tab is the ability to identify potential resource constraints within an item portfolio. The Demand vs Capacity tab assumes that resource demand for your most important item will be filled first and that they will be sorted according to importance or strategic value. The sort order can be specified using the Organize tab in the Datasheet Properties dialog box. As you move down an item list, capacity will be consumed by each item in turn, until, potentially, the demand for resources exceeds resource capacity.
The resource demand values display in the right part of the view. When resource demand is less than capacity, demand values for each corresponding item is displayed in black (positive variance). When resource demand is greater than capacity, demand values for each corresponding item is displayed in red (negative variance). When the overall demand values are calculated in the lower pane, and compared with capacity, you will see the total variance for the portfolio by time period and by role. In addition to colors, you can enable a watermark, which adds a red line and a watermark that uses a graphical representation when demand exceeds capacity. The watermark will appear at the first point where capacity is exceeded.
You can change the information available in the Demand vs Capacity tab by changing the starting or ending dates, by adjusting the calendar period, or by changing the units upon which the analysis is based. Click Apply to recalculate the information.
Datasheet demand values for each item is equal to the sum of all allocations in the specified time frame. Demand is represented by rows, which correspond to each item in the datasheet. Demand for an item can be viewed over time and for each resource role allocated to that item. Datasheet capacity values for each item is derived from the calendar settings for all resources on all resource teams included in the Demand vs Capacity Filters tab in the Datasheet Properties dialog box in the specified time frame. Capacity is displayed in the Capacity row at the lower part of the view. The total demand displays in the Total Demand row, which includes both demand in the datasheet. Other Demand includes demand for any item not included in the datasheet, such as those outside the selected item hierarchy level, or those filtered out in the Datasheet Properties dialog.
If you want to include demand and capacity values for each resource role as well as the time period total, select the Show Resource Roles check box.
In addition to the text coloring, you can select the Show Watermark dialog check box on the view toolbar to add a red line and watermark that provides a more graphical representation when demand exceeds capacity. The watermark appears at the first point in an item list, from top to bottom, where capacity is exceeded.
Demand vs capacity information can be viewed from the Demand vs Capacity tab in the Reports module.
