Evaluating Application Criticality
Criticality of an application is assessed related to criteria linked with the business, to functionalities covered and to technologies used. The evaluation of an application therefore involves different user types. For more details on users, see HOPEX IT Portfolio Management Profiles.
It is also possible to evaluate a set of applications at the portfolio level. This evaluation is performed by the application portfolio manager. See "Evaluating Application Assets", page 83.
Evaluation Criteria
Evaluation of an application relates to:
• its Business Value enabling evaluation of the nesting level of the application in enterprise production.
• Level 1: operational business processes will be stopped if the application no longer functions and a workaround solution exists.
• Level 4: major production processes will be stopped in the case of application malfunction with no workaround solution.
• its Business Value enabling evaluation of the support level of the application in enterprise process.
• Level 1: low level
• Level 4 the application is critical from a functional viewpoint, since it supports key processes on its own.
For more details on businesses addressed and functionalities covered, see Defining Application Functional Scope.• its Technology enabling assessment of evolution possibilities of the application from the techniques that support it.
• Level 1: technology is frozen
• Level 4: corresponds to a flexible and upgradable technological platform.
For more details on technologies, see Specifying the Technologies of an Application.Creating an Assessment Measure
You can evaluate an application at precise moments, by creating a new evaluation measure each time.
To create an evaluation measure:
1. Click the icon of the application to evaluate and select Properties.
2. In the properties drop-down list, click the Assessment page.
3. Click the Evaluate button.
The creation window opens.
4. Indicate the value of each criterion as well as the evaluation end date.
From evaluation data, a report allows you to classify applications of the installation in a matrix and to rapidly identify the applications to be upgraded. See "Accessing Embedded Reports in a Portfolio", page 99.
