I found a guide on Process Impact Assessment that provides a step-by-step overview of conducting an assessment of the impacts a process change will have on an organization. It is designed for Business Change Practitioners, HR Professionals, Project Managers, Program Leads, Consulting Firms, IT Professionals, Government Agencies, Corporations, Businesses, and many more. The guide includes templates and samples to help you conduct a best-in-class business process impact assessment.
If you are interested in conducting a Change Impact Assessment, I found another guide that outlines everything you need to know, including impact assessment templates, checklists, and tools for conducting the best business impact assessments for all types of organizational change.
Please note that these guides are not my own tools. I can only provide information from the web search results I found. If you have any other questions, feel free to ask!
