What key output of the 'deployment model development and improvement' process can be used to...

In ITIL 4, the deployment model development and improvement process involves creating or refining models to enhance deployment effectiveness. Implementing a newly updated deployment model typically requires formal authorization and coordination, which is achieved through a change request (Option B). A change request initiates the process to assess, approve, and execute the model update in a controlled manner, ensuring alignment with organizational governance and other practices like change enablement.

Option A (Lessons learned):Incorrect, as lessons learned are an output for improving future processes, not a trigger for implementing a new model.

Option B (Change request):Correct, as a change request is the formal mechanism to propose and implement a new or updated deployment model, per ITIL 4’s integration with change enablement.

Option C (Updated knowledge management articles):Incorrect, as knowledge articles support documentation and training but do not trigger implementation.

Option D (Deployment review reports):Incorrect, as review reports provide insights or feedback, not the authorization needed to implement a model.
