Hide Control Practices  help

  1. Assess the impact of any major upgrade and classify it according to specified objective criteria (such as business requirements), based on the outcome of analysis of the risk involved (such as impact on existing systems and processes or security), cost-benefit justification and other requirements. Follow normal system development and implementation processes as appropriate for the nature of the change.
  2. Obtain agreement on and approval of the implementation of the development and implementation process with the business process sponsor and other affected stakeholders. Ensure that the business process owners understand the effect of designating changes as maintenance or major upgrades.
