PDD stands for Process Definition Document. This is a fundamental artifact within the Blue Prism Robotic Operating Model (ROM). The PDD provides a detailed, step-by-step description of the "as-is" business process that is being considered for automation. It captures all process steps, rules, inputs, outputs, and exception handling procedures, serving as the primary blueprint for the development team to build the automated solution accurately.

A. Process Document Definition: This is an incorrect arrangement of the words. The document itself is the definition of the process, not a definition of a document.

C. Process Design Document: This is incorrect. The document that details the technical design of the automation solution is the Solution Design Document (SDD), not the PDD.

D. Process Document Design: This is an incorrect and grammatically awkward arrangement of the words and is not a recognized term in Blue Prism methodology.

1. Blue Prism University (BP University). ARA02 - Blue Prism Certified Associate Developer Exam - Preparation. In the module covering the Blue Prism Robotic Operating Model (ROM), the PDD is explicitly defined as the "Process Definition Document," a key deliverable of the "Define" phase.

2. Blue Prism Limited. Robotic Operating Model (ROM) v2. Section 2.2, "Define," describes the creation of the Process Definition Document (PDD) as the output of the process analysis and definition stage, which captures the detailed manual process.

3. Blue Prism Limited. Blue Prism - Process Definition (PDD) Template. The official template document provided by Blue Prism is titled "Process Definition Document," confirming the correct expansion of the acronym. This document's introduction states its purpose is to "provide a detailed definition of the business process selected for automation."
