OPS05-03 Defining a Change Process

High

Before establishing a standard change management process, define each stage clearly.

• Change initiation: Before initiating a change, specify the change content and reason. Specifying the change information can reduce the workload of the change evaluator and clarify the change significance. Change information includes:
  • Basic information (title, time, changer, and reason).
  • Change information (system, scenario, and type).
  • Change solution (change implementation, rollback, and verification).
• Change approval: The person in charge of the change system reviews the change to check the change risk level. If the change risk level cannot be controlled or predicted, more details should be provided for the change solution or the change should be prohibited. The change approval process can involve several persons, including the business owner, team TL, and technical TL. Personnel involved in the change can be determined based on factors such as the impact degree and scope of the change.
• Change execution: The executor confirmed at the change initiation stage assigns the execution tasks to maintain that the change is accurately executed by the technical personnel related to the change content.
• Change verification: After the change is complete, check the change object and content to maintain that the change does not affect actual business. After the check is complete, release the change result.
• Change closure: After the change is complete, the change task is closed. Retain the change records to ease subsequent change data operations and analysis.
