The next step is to design your IT services based on customer information and best practices of IT service management (ITSM). ITSM is a set of processes, policies, and tools that help you plan, deliver, and improve IT services. You can use frameworks such as ITIL, COBIT, or ISO/IEC 20000 to guide your service design. This includes creating a service portfolio, which is a collection of all the IT services you offer or plan to offer. Additionally, you should create a service catalog that describes the current and available IT services, along with their features, benefits, and service level agreements (SLAs). Service level management is a process that ensures your IT services meet the agreed quality and performance standards. Lastly, you should create a service design package that specifies the requirements, specifications, and resources of each IT service, as well as transition and operation plans.
