OEM projects can accelerate growth—but they also introduce risks across specifications, quality, timing, cost and compliance. Below we summarize the most frequent failure modes and practical preventive actions used by experienced B2B teams.
Why Risk Management Matters
Small misses early (unclear specs, unverified parts, late approvals) multiply into delays, rework, and warranty cost. A structured approach—clear documentation, gated builds, QC plans and change control—keeps projects predictable and scalable.
Top Risks & How to Avoid Them
1) Unclear Specifications & Scope Creep
Risk: Ambiguous KPIs (power, noise, lifetime), missing tolerances, or late feature adds. Prevent: Freeze a signed SOW/spec pack (drawings, tolerances, test methods), create golden samples, and route any change via ECR/ECO with cost/timing impact.
2) Quality Escapes
Risk: Defects pass to customers due to weak inspections. Prevent: Define QC plan & AQL at IQC/IPQC/OQC, use first article/PPAP, implement SPC on critical dimensions, and run pilot builds (EVT/DVT/PVT) before MP.
3) Delay in Tooling, Materials or Logistics
Risk: Tool rework, long-lead components, export hiccups. Prevent: Baseline a Gantt with buffers; lock AVL, dual-source critical parts, pre-book logistics during peak, and conduct DFM reviews before cutting tools.
4) IP Leakage
Risk: Drawings/firmware used outside the project. Prevent: NDA + MSA with IP ownership, tooling custody clauses, controlled file access, and sub-supplier restrictions; register trademarks/patents early.
5) Cost Creep & Hidden Charges
Risk: BOM drift, unquoted changes, commodity swings. Prevent: Maintain a costed BOM, set price-validity and review triggers (Cu/Al/Li, FX), and require ECO cost sign-off and open-book quotes for alternates.
6) Compliance & Certification Surprises
Risk: Failing CE/EMC/RoHS/REACH/ETL late in the cycle. Prevent: Plan compliance in the spec; review CB/CE test plans, materials declarations, and run pre-compliance early with certified labs.
7) Component Obsolescence / EOL
Risk: Key parts go EOL after launch. Prevent: Check lifecycle status, build an AVL with second sources, subscribe to PCN alerts, and define last-buy & re-qual timelines.
8) Weak Communication & Slow Response
Risk: Time-zone gaps, unclear owners. Prevent: Set SLAs (ack/first action/closure), publish a RACI, hold weekly builds-of-record, and use a shared tracker for issues & decisions.
9) Tooling Ownership & Maintenance Gaps
Risk: Disputes over molds/fixtures; downtime. Prevent: Contract for tool ownership/ID, storage and PM schedules, life shots, and repair/insurance responsibilities.
10) Sample ≠ Mass Production
Risk: MP units differ from approved samples. Prevent: Lock golden sample + control plan, photograph critical assemblies, and verify with PVT and GR&R on gauges before MP sign-off.
Quick Reference: Risk → Early Signals → Mitigation
| Risk | Early Signals | Mitigation |
|---|---|---|
| Spec gaps | Frequent clarifications, redraws | Signed SOW, DFM review, ECO gate |
| Quality escapes | Rework rising, inconsistent CTQ | AQL plan, PPAP/FAI, SPC & CAPA |
| Supply delays | Late PO confirms, tight LT | Dual source, buffer, locked AVL |
| Cost creep | Untraceable BOM changes | Costed BOM, review triggers, ECO sign-off |
| Compliance fail | Late lab bookings, redesign | Pre-compliance, materials declaration |

Frequently Asked Questions
What early documents should we sign?
An NDA, SOW/spec pack, and a master supply agreement with IP/tooling ownership, QC plan (AQL), SLA, change control and warranty terms.
How do we keep schedule realistic?
Use a gated plan (EVT→DVT→PVT→MP), freeze specs before tooling, and buffer long‑lead items. Track issues weekly with owners and due dates.
What’s the minimum QC we should require?
Incoming IQC on critical parts, IPQC at key stations, and OQC with agreed AQL and defect classification; retain golden samples and records.
When should we book certification labs?
Align pre‑compliance tests during DVT; reserve formal certification near PVT to avoid queue delays and late‑stage redesigns.
How to manage engineering changes?
Every change goes through ECR/ECO with impact on cost, schedule, compliance and inventory; communicate cut‑in version and lot codes.
