What step in the troubleshooting process involves asking the customer about previous work done at the premises?

The step in the troubleshooting process that involves asking the customer about previous work done at the premises is "analyze the situation." During this stage, the technician gathers all relevant information to understand the context of the issue. Engaging the customer in conversation about prior work helps identify any potential factors that could contribute to the current problem, such as recent installations, repairs, or modifications that may have been made. This information is crucial for forming a complete picture of the problem, which can lead to a more accurate diagnosis.

The other steps in the troubleshooting process focus on different aspects. "Identify the problem" involves defining the specific issue the customer is experiencing. "Implement a solution" refers to taking action to resolve the identified problem, while "verify the repair" entails checking to ensure that the solution has effectively resolved the issue and that the system is operating correctly. Each of these steps is important, but analyzing the situation is key in gathering the right background information to inform the entire troubleshooting process.
