Mission Profiles

Mission Profiles can help you to ensure that your testing is representative of the expected conditions of actual use by checking, at defined "convergence" points, whether expected usage and actual usage are acceptably close. The ReliaWiki resource portal provides more information about operational mission profile testing at: http://www.reliawiki.org/index.php/Operational_Mission_Profile_Testing.

To add a mission profile folio to a project, choose Home > Insert > Mission Profile or right-click the Mission Profile folder in the current project explorer and choose Add Mission Profile.

To use a mission profile folio in RGA, do the following:

If desired, you can also link a profile with a data sheet in order to group the data.

Convergence Points Sheet

On the Convergence Points sheet, enter the times at which you want to check that the expected usage and the actual usage either meet their expected averages or fall within an accepted range [1].You must include a minimum of three convergence points in the analysis. The test times between the convergence points do not have to be the same.

The following example shows a convergence points sheet with four times defined.

All of the define convergence points must be included in all of the profile sheets that you add to the folio. To automatically add the defined convergence points to each profile sheet, choose Mission Profile > Mission Profile > Transfer Convergence Points to Profile Sheets or click the icon on the control panel.

Profile Sheet

Each profile sheet represents a different part of testing (e.g., a different task that the system performs, etc.). By default, each new mission profile folio starts with one profile sheet. You can add additional profile sheets to the folio by choosing Mission Profile > Mission Profile > Insert Profile Sheet.

At a minimum, each profile sheet must contain the times that you entered on the convergence points sheet. It may also contain any additional times at which usage is observed and recorded.

The profile sheet contains the following information:

The following example shows part of the data in a profile sheet.

Validating the Mission Profile

After you have entered all of the data, you can validate the profile to make sure that all necessary data points have been entered. To do so, choose Mission Profile > Mission Profile > Validate Mission Profiles or click the icon on the control panel.

This feature checks that all convergence points are in all the profile sheets and sorts the data by the Cumulative Time column.

Note: Validation also occurs when you generate a plot of the mission profile. If all of the data points have been entered, all of the profile sheets are marked as being verified.
