IntervalMAX can project cost and workload changes that will result from the implementation of recommended intervals. These projections are published in the Interval Impact Report.  To assess the impact of interval changes on workload and on cost, it is necessary to indicate inventory sizes, hourly rates, hours per test or calibration, and parts costs. These data can be entered via the Cost Variables Screen, which is accessed by selecting the Cost Variables option from the Controls menu on the Main Screen.
 

The Cost Variables Screen shows inventory, cost and labor variables by manufacturer/model. The fields on this screen that are used in computing projections are: Avg Hours Per Cal - the average number of hours for each service action for the model number, Avg Rate - the average burdened hourly rate for each service action, and Avg Materials - the average cost of parts and other materials for each service action. 
 

The averages are computed from hours, rate and materials information that are included in the service history records imported into IntervalMAX.   If such data are not included, IntervalMAX applies the default Hrs/Cal, Rate and Materials figures shown in the Cost Variables Defaults section of the screen.  These defaults may be entered on the Cost Variables Screen or the Analysis Parameters Screen.
 
The data in the hours, rate and materials fields may be superseded at the discretion of the IntervalMAX System Administrator. This is done by typing the desired information in the Cal Hrs Override, Rate Override or Materials Override fields.
