Question

A company has hired a consultant to review the production storage infrastructure and provide suggestions on improving performance. The consultant has identified a bottleneck in the production switching fabric and successfully tested the solution in a lab environment. Which of the following should the consultant perform NEXT, according to best practices?

Options

  • AImplement the solution in production since it was tested in the lab.
  • BEstablish a plan of action to implement the solution in production.
  • CPerform a root cause analysis of what caused the bottleneck.
  • DEstablish a theory describing the possible issue in the production network.

Why each option

After successfully lab-testing a solution, best practice in change management requires establishing a formal plan of action before touching production systems.

AImplement the solution in production since it was tested in the lab.

Implementing directly in production without a formal plan violates change management best practices because production environments carry risks and dependencies not present in a lab, regardless of successful lab testing.

BEstablish a plan of action to implement the solution in production.Correct

The standard change management process requires a formal plan of action after lab validation and before any production implementation. This plan covers the change window, rollback procedures, stakeholder notification, and risk assessment - safeguards that lab testing alone does not address.

CPerform a root cause analysis of what caused the bottleneck.

Root cause analysis is an earlier troubleshooting step used to identify the underlying cause of the bottleneck - this has already been completed by the time the consultant reaches the testing phase.

DEstablish a theory describing the possible issue in the production network.

Establishing a theory of probable cause is one of the first steps in troubleshooting and is already completed well before lab testing occurs.
