Specifications cannot be created in which of the following steps?

In the context of the Pega Rules Process Commander (PRPC), the ability to create specifications pertains to the various development and design stages of an application. During the "Create Processes" step, application developers typically define the necessary processes and workflows, which include the specification creation as part of the overall design. In the "Project Explorer" step, specifications can also be formulated as developers explore and manage project components.

However, during the "Review Application" step, the focus shifts to evaluating and validating the already defined processes and specifications rather than creating new ones. This phase is more about assessing the coherence and correctness of what has already been developed, ensuring that the application aligns with stakeholder requirements and preparing for deployment or further iteration.

Consequently, the option referencing the "Review Application" step accurately identifies a stage in which specifications cannot be created, since the primary objective is to analyze rather than to create new content. This reflects the developmental flow in Pega, indicating that there are specific phases designated for creation versus evaluation of application components.
