Which process occurs after the pre-installation walkthrough?

The correct answer is the development of an installation plan. After completing the pre-installation walkthrough, technicians typically gather information about the site, the specific customer needs, and any potential challenges that may arise during the installation process. This information is crucial for creating a comprehensive installation plan, which outlines the necessary steps, resources, and timeline required to execute the installation effectively.

The development of the installation plan serves as a roadmap that helps ensure a smooth and efficient installation process, accommodating any special requirements identified during the walkthrough. It enables the technician and the team to anticipate potential issues and deploy the necessary tools and personnel accordingly.

In contrast, other options do not directly follow the pre-installation walkthrough. For instance, while customer feedback is valuable, it is generally addressed during or after the installation to adapt or modify services based on their experience. Scheduling maintenance visits pertains to post-installation support rather than the immediate next steps after the walkthrough. Lastly, selection of installation personnel typically occurs prior to or as part of the planning process, rather than as a subsequent action.
