    You say

    Line 3 had 47 hours unplanned downtime in June. Scrap rate jumped to 8.2%. Find the root cause and give me a corrective action plan.

    Your agent does

    ROOT CAUSE ANALYSIS — Line 3 Downtime

    5 WHYS CHAIN: Why 1: Machine stopped → Bearing failure Why 2: Bearing failed → Overheating Why 3: Overheating → Cooling blocked Why 4: Cooling blocked → PM skipped 3 cycles Why 5: PM skipped → No PM scheduling system

    ROOT CAUSE: Absence of systematic PM tracking

    CORRECTIVE ACTIONS: → Immediate: Manual PM check all Line 3 → 30 days: SAP PM module implementation → 60 days: Overheating sensor alert

    Recurrence risk: HIGH without systematic fix

    About This Skill

    Most teams stop at the symptom — "machine broke down" — without finding the real cause. MD 5 Whys Analyst forces systematic depth: 5 levels of why, validated against your data, not guesswork. WHAT IT DOES: - 5 Whys chain analysis (5 levels deep) - Ishikawa fishbone diagram (6M framework) - Corrective action plan with owner + deadline - Recurrence prevention checklist - RAG scoring on root cause confidence WHY USE THIS: Built for lean manufacturing, quality teams, and operations managers who need to close NCRs fast — without spending hours in a whiteboard session. SEE IT IN ACTION: Input: "Line 3 had 47 hours unplanned downtime in June. Scrap rate jumped to 8.2%." Output: Root Cause: Absence of systematic PM tracking 5 Whys Chain: Bearing failure → Overheating → Cooling blocked → PM skipped → No PM system Actions: Immediate manual PM check + SAP PM module in 30 days OUTPUT FORMATS: → In-chat: 5 Whys chain + fishbone summary → PPTX: RCA Presentation → DOCX: NCR Closure Report → XLSX: Corrective Action Tracker WORKS WITH: Any industry · Manufacturing · Logistics · Healthcare · 14 languages output · Any ERP data KNOWN LIMITATIONS: - Depends on quality of problem description — vague inputs produce shallow analysis - Does not replace on-site investigation for safety-critical incidents - Not a substitute for certified quality auditor (ISO 9001, IATF 16949) sign-off Built on MD-UBAOS™ v4.6 — 9 Hard Gate quality-controlled analysis framework.

    designing-hybrid-context-layers

    Architects the right retrieval strategy for every query — teaching your agent when to use RAG, a knowledge graph, or a temporal index instead of defaulting to vector search for everything.

    diagnosing-rag-failure-modes

    RAG fails quietly. It retrieves documents, returns confident-looking answers, and misses the question entirely — because the question required connecting facts across documents, reasoning about sequence, or tracing causation. This skill gives you a five-question diagnostic checklist that classifies any failing query as either RAG-safe or structurally RAG-incompatible, then maps it to the specific failure pattern and the architectural fix that resolves it.

    synthesizing-institutional-knowledge

    Builds the organizational memory schema your AI agent needs to answer why — capturing decision provenance, causal chains, and event context that embedding-based retrieval permanently discards.
