A carefully designed categorization scheme will simplify how incidents are entered into the system, reduce errors in miscategorization, and assign ownership. But there is no one right way to create a categorization scheme. There’s no template. Every organization is different. The products and services are different. The service levels are different. The customers are different, and the required information to track is different. Even the reports differ. There is no master categorization to use because it is up to your organization to define what works for your environment.
