Process Owner A person in this role has the ongoing responsibility and accountability for the successful design, development, execution, and performance of a complete end‐to‐ end (cross‐functional) business process.
Process ownership can be adopted full time or as an additional responsibility, as a line or staff function.
Executive process owners (Enterprise Process Owners and Chief Process Officers) commonly have financial responsibility for groups of business processes. They have an inherent investment in the successful execution of cross‐functional business processes that are key to the success of the company.
Process owners are among the essentials to business process success. A business process without an organizationally influential process owner is like a ship without a rudder, propeller, and sails — the business process can’t execute in the most efficient and effective way possible.
