Validate MTPD calculations  

 

The MTPD validation screen

Within the business continuity software the BIA calculations for RTO, MTPD and criticality are semi-automated although the User can overwrite any values that are not considered suitable. This screen deals with those values and the supportive calculations for products, service & other critical objectives. The User can select to validate RTOs, MTPDs, or criticality by clicking on the respective radio buttons.  Amendments to the impact ratings are done in Module 3 using the BIA functionality. Click on the Validate button and then click the MTPD radio button to display the following screen:

 

MTPD process

The MTPD values (in terms of elapsed hours from the point of disruption) represent the maximum tolerable period of disruption calculations for each product, service or other critical objective. If they have already been set up by the User, BIA impact values are displayed in the validation area for each of the BIA time periods for up to a maximum of five impact categories.  The highest rating for each time period is then displayed in the right hand column. The User managed system-wide BIA settings are then used to calculate where the RTO value is to be set. If, for example, the MTPD value has been chosen by the User to be set prior to the impact reaching a "disastrous" level then the MTPD value will be calculated as the period before the highest rating reaches "disastrous" or above.  If the User does not agree with these settings then the User can either adjust the system-wide settings, adjust the BIA ratings for the related critical objective or over-write the result. If there is no over-writing of the MTPD values for the selected item then this value will be blank in the validation screen. The final MTPD values are subsequently transferred during the mapping process to each of the processes or activities that are mapped to this products, service & other critical objective.


Using the MTPD validation screen

The list box located at the top left of the screen contains the products, services or other critical objectives that have been set up in the system. This list is sorted in ascending RTO value order.  Moving between the RTO, MTPD and criticality validation screen is achieved using the radio buttons to the top right of the screen.  Clicking through the main list box selects each record in turn for validation purposes.

In the main validation area the five system-wide time periods selected by the User organization are shown together with the impact categories that have been set up for the selected record.  For each time period within each impact category an impact level has been set. The far right hand column displays the highest rating for that record in each time period across the impact categories.

Beneath the first line in the right hand column the system-wide setting for MTPD values is shown.  This setting value is then applied to the rating shown above and the results shown in the next row down.  If a manual overwrite value has been added to the selected record then this value will be shown in the next row down.  The final MTPD value for the selected record is displayed in the bottom right hand corner of the screen.
