What is the first step required in a change management process?

The first step in a change management process typically involves establishing an application overlay, which allows you to encapsulate and manage changes separately from the main application. By creating an application overlay in the Designer Studio, you set the groundwork for implementing modifications without directly altering the core components of the application. This is crucial, as it provides a controlled environment for testing and iterating changes before they impact the live application.

In contrast, the other options involve subsequent steps in the change management process. For instance, creating a change request in the Decision Manager portal usually follows the identification of the need for a change and the creation of an application overlay. Similarly, the creation of a revision management package and a revision in the Decision Manager portal are processes that also depend on having a well-defined overlay to ensure changes can be managed effectively. Therefore, establishing an application overlay is essential as the initial step that sets the stage for all subsequent change management activities.
