Answer: b. false
Explanation: Support functions, while important, are not directly responsible for managing and improving the efficiency of an organization's conversion processes. Conversion processes typically refer to the core operational activities of an organization that directly create value. Support functions, such as HR, IT, or administrative services, are essential for providing the necessary support and resources for these conversion processes to function efficiently, but their primary role is not to directly manage the conversion processes themselves. Instead, they facilitate and enable the core functions of the organization.
