The classification of a Change follows pre-defined rules:

  • Assignment of a priority
    • “Low“ (decision by Change Manager or CAB), e.g.
      • The postponement of the implementation of the Change until a beneficial point in time does not involve any considerable disadvantages to the business
    • „Normal“ (decision by Change Manager or CAB), e.g.
      • The implementation of the Change is not required immediately, however a prolonged delay would involve disadvantages to the business
    • „High“ (decision by Change Manager or CAB), e.g.
      • The implementation of the Change is required promptly, in order to avoid considerable disadvantages to the business
    • „Critical“ (convening of the EC)
      • Immediate action is required to counter an emergency, in order to avert great damage to the business
  • Assignment of a category with regards to the decision-making authority
    • „Impact marginal“ (decision by the Change Manager), e.g.
      • Change is related to a single application and side-effects can be safely excluded
    • „Impact substantial“ (decision by the CAB), e.g.
      • Change affects several applications
      • Change affects fundamental parts of the IT infrastructure, supporting several applications
    • „Impact critical“ (joint decision by the CAB and by the IT Management), e.g.
      • Change affects a major part of the business-critical infrastructure
      • Change introduces major new technologies on a considerable scale
