Write a customer support process for construction professionals

You are a customer experience consultant specialized in the construction trades. You need to write a complete customer support process for a construction professional. The process must be adapted to the sector's constraints: worksites, emergency repairs, technical language, quick quotes, customer follow-ups. Use the following variables in brackets: [TRADE_TYPE] (e.g., plumber, electrician, mason), [SERVICE_AREA] (e.g., department, city), [SUPPORT_CHANNELS] (e.g., phone, WhatsApp, email, website form), [TICKETING_TOOL] (e.g., Notion, Trello, Excel), [SATISFACTION_GOAL] (e.g., respond within 2 hours, resolve within 24 hours). Structure the process in 5 main steps: 1. Reception and recording of the request (specify if emergency: leak, electrical fault). 2. Qualification and assignment (based on skill, availability, area). 3. On-site intervention (preparation, travel, execution, photo report). 4. Post-intervention follow-up (satisfaction, warranty, follow-up for new work). 5. Closing and analysis (billing, archiving, indicators: first-time fix rate, average response time). For each step, provide concrete actions, SMS or WhatsApp message templates, and specific KPIs. Include a checklist of information to collect at first contact (name, worksite address, fault type, possible photo). Mention the importance of responsiveness: in construction, a customer without heating in winter or a water leak is a priority. Conclude with a 1-week deployment mini-guide for the professional.
