This control formalizes the idea that we need to keep track of our production systems and maintain quality documentation for easy reference. Most of this control is naturally met by the emphasis we have on documentation, here at IllumiDesk . The remainder of this control is meant to ensure we are publishing any institutional knowledge about how systems interact and that we consider high-level system views as well as individual components. Testing of this control is to see if IllumiDesk has comprehensive document information about our systems and system components. We easily meet this requirement given the nature of our handbook and IllumiDesk's transparency.
