Planning A Cost Object's Output and Primary CostsEdit


Every Resource pool and Business process in an RCA model has a plan similar to the example shown in Figure 5 below. For every Resource pool and Business process, the model (based on the demand for its services) calculates the user specifies an output quantity and the capacity. It is important to note that Resource pools must have both an output quantity and a capacity quantity to enable the rate calculations described earlier to function.

Figure 5 - Resource Pool 'Plan' example

Output Quantity Planning: A Resource pool’s output quantity equals the demand for its services i.e., the total consumption required by consuming Resource pools and final cost objects. The output is therefore not planned manually by the user but calculated by the application, based on the consumption relationships established and the planned demand from final cost objects. The user must provide the capacity figure, either by typing it into the capacity report (see Figure 30 - Maintain Capacity template) or by uploading the information as shown in Figure 38. Calculated output quantities must be reviewed to ensure they do not exceed Resource pool capacities. Output for Resource pools could be less than capacity. Capacity and Output for Business processes will always be the same (only resource pools have capacity, business processes do not).


With Primary Cost Planning, Primary costs are planned in dollars, not quantities and must be split into their fixed and/or proportional components—an example of this is visible in Figure 5 below, for cost element 60011-Supplies. This cost element 60011 is also the GL element in the financial system. Secondary Cost Planning is discussed in the next section Relationships in an RCA Model.
