Business process owners are the most important to include in the assessment of existing IT risk scenarios, as they have the authority and responsibility to manage the business processes and their associated risks and controls, and to provide the business perspective and requirements for the IT risk scenarios. Technology subject matter experts, business users of IT systems, and risk management consultants are not the most important to include, as they may have different roles and responsibilities related to the technical, operational, or advisory aspects of IT risk scenarios, respectively, but they do not own the business processes or the IT risk scenarios. References = CRISC Review Manual, 7th Edition, page 101.
