Final answer:
The next step before making any changes for an ITWx client is to assess the change request and then proceed with planning and implementing the change.
Step-by-step explanation:
The next step before making any changes for an ITWx client that calls in requesting a change after the Service Request (SR) is created is to assess the change request. This involves evaluating the impact of the requested change on the existing system, analyzing the feasibility of the change, conducting risk assessments, and determining the resources needed for the change.
Once the change request has been assessed and approved, you can proceed with planning and implementing the change. This may involve designing the new solution, testing it in a controlled environment, coordinating with other teams or stakeholders, and executing the change according to established processes and procedures.
