Service Expert Knowledge Preservation System
"Most service organizations we talk to have 3-5 people who can fix anything — and in 5 years, most of them will be retired. The question isn't whether to capture that knowledge, it's whether you'll still be able to."
The Problem
Experienced field technicians carry 20-30 years of troubleshooting knowledge in their heads — equipment quirks, undocumented fixes, customer-specific configurations. When they retire or leave, this knowledge walks out the door. New technicians take 12-24 months to reach competency, making 2-3x more repeat visits during ramp-up. Meanwhile, organizations face a demographic cliff: 27% of manufacturing workers are 55+, and skilled replacements aren't available. First-Time Fix Rates sit at 65-75% largely because junior technicians can't access the tribal knowledge that veterans use instinctively.
Current State
Knowledge lives in individual technicians' heads, scattered across personal notebooks, WhatsApp groups, and tribal conversations. When a junior tech gets stuck, they call a senior colleague — interrupting their work. Formal knowledge bases exist (SharePoint, Confluence) but are poorly maintained, hard to search, and contain generic manufacturer documentation rather than field-proven solutions. Training programs teach theory, not the practical workarounds that solve 80% of field problems.
GenAI Solution
AI reads: Historical work orders, resolution notes, equipment manuals, expert interview transcripts, photo archives, manufacturer bulletins, customer-specific configuration records. AI generates: Contextual troubleshooting guidance when technician describes a symptom (text or voice), ranked by relevance to specific equipment model, customer site, and failure pattern. AI reasons: Matches current symptoms against historical resolution patterns, identifies similar cases across different sites/equipment, surfaces fixes that worked for this specific combination. Human gets: Guided troubleshooting steps with confidence scores, relevant past cases, and an 'ask the expert' escalation path. Key capability: semantic search + synthesis across unstructured knowledge sources.
Key Differentiator
Traditional knowledge bases are static document repositories — they require someone to write articles, maintain them, and users to know the right search terms. GenAI creates a conversational expert that synthesizes across all knowledge sources (work orders, manuals, expert interviews, photos) and understands equipment context — like having the most experienced technician on every call.
Example Workflow
- 1 Junior technician arrives at site, finds compressor unit cycling irregularly
- 2 Opens mobile app, describes symptom: 'Carrier 30XA cycling every 3 minutes, high head pressure'
- 3 AI searches: past work orders for this unit, all 30XA models across fleet, similar symptoms in knowledge base
- 4 AI returns: 'Three similar cases resolved. Most likely: condenser fan relay failing intermittently (resolved 4 times on 30XA units at high-ambient sites). Check relay contacts for pitting. Parts: 38HQ660014.' Also surfaces: manufacturer bulletin from 2023 about relay upgrade.
- 5 Technician follows guidance, resolves issue on first visit
- 6 Resolution automatically captured and added to knowledge base for future reference
Prerequisites
- Historical work order data (ideally 2+ years, 1000+ records)
- FSM/CMMS system
- Equipment/asset master data
- Willingness of senior technicians to participate in knowledge capture
Red Flags
- Very low equipment complexity (simple, standardized jobs)
- High technician turnover (knowledge capture ROI insufficient)
- No historical work order data
- All technicians are relatively junior (no experts to capture from)
- Fewer than 25 field technicians
Complexity Drivers
Knowledge extraction and curation is labor-intensive; RAG system requires careful tuning; integration with FSM/CMMS; multi-language; need for ongoing knowledge refresh; cultural adoption challenges with senior technicians
Risk Factors
["Senior technicians reluctant to share knowledge (perceived job security threat)", "Poor historical data quality", "Hallucination risk on safety-critical troubleshooting", "Low adoption by field technicians", "Knowledge staleness without ongoing capture process"]
Value Metrics
First-Time Fix Rate (FTFR); Mean Time to Resolution (MTTR); repeat visit rate
FTFR 65-75%; 1.8 hours/day per technician searching for information; 14-24% avoidable truck rolls
FTFR 80-88%; 0.5-1 hour/day searching; 3-10% avoidable dispatches

Service Demand Interpretation and Capacity Matching
The difference between a profitable service call and a money-losing one often comes down to a 5-minute dispatch decision — and right now, that decision depends entirely on who happens to be on the desk.
Intelligent Work Order Documentation from Field Notes
Most field service teams we talk to say their technicians are great at fixing things but terrible at writing about it — and the back office spends half its time translating scribbled notes into usable records.
Production Constraint Reasoning and What-If Dialogue
Most manufacturing companies we work with have planners who are incredibly good at their job — but they're answering the same types of questions over and over again, manually, because their planning system can only show schedules, not explain them.
