  • „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
