Purpose: Equip repairers with the necessary product information and technical documentation to perform repairs effectively. Implementation: Comprehensive Repair Guides: Develop detailed repair guides covering common and complex repairs, including step-by-step instructions, troubleshooting tips, and parts lists. Spare Parts Information: Provide a database of compatible spare parts, including specifications, sources, and availability. Interactive Tools: Offer interactive tools such as diagnostic software or virtual repair assistants to help identify issues and guide repair processes. Impact: Ensuring repairers have all the information and resources they need minimizes errors, improves repair quality, and reduces the time required to complete repairs. The flow is similar to the Resident DIY Repair (UC_A_3_1 Support DIY Repair), but the expectation is that the professional repair man has more (technical) resources available and has (much) more technical know-how.
