A PDD is a Process Definition Document that describes the business process to be automated, its inputs, outputs, exceptions, and dependencies. It is a key document for the RPA project, as it serves as the basis for the solution design and development2. The business analyst is the one who leads the creation of the PDD, by gathering the requirements from the subject matter experts, analyzing the current state of the process, and documenting the steps and logic of the process in a clear and detailed manner. The business analyst also ensures that the PDD is aligned with the client’s expectations, objectives, and standards, and that it is reviewed and approved by the relevant stakeholders before handing it over to the RPA developers13.
