Which document describes the as is and to be processes in detail?

The document that describes the "as is" and "to be" processes in detail is the Process Definition Document (PDD). This document serves as a comprehensive guide outlining the current state of a process (the "as is") and the desired future state (the "to be"). It typically includes various elements such as process flows, stakeholder roles, business rules, and performance metrics. By contrasting the "as is" with the "to be," the PDD helps stakeholders understand what changes are necessary, why they are needed, and what the projected improvements will be. This thorough documentation is instrumental in the automation process, as it provides a clear roadmap for implementation.

In contrast, other options serve different functions. Traceability is focused on ensuring that each requirement is tracked throughout the development lifecycle, while a process assessment involves evaluating the efficiency and effectiveness of current practices without necessarily mapping out future processes in detail. An application tracker is commonly used to monitor various applications and their statuses but does not delve into the detailed process analysis provided by a PDD.
