What is operational due diligence?
Operational due diligence (ODD) is the structured review of how a company produces, delivers, supports, and scales its product or service. Where financial due diligence validates historical numbers, operational DD asks: can this business keep producing those results under a new owner, with growth targets, without the founder living in the plant?
It spans facilities and capacity, process documentation, quality systems, supplier risk, inventory discipline, service delivery metrics, labor stability, and systems that coordinate the work. For manufacturers, that means shop-floor reality. For software, it means delivery, support, reliability, and change management. For services, it means utilization, staffing models, and client delivery risk.
Why operational diligence wins or loses deals
Protects the model
Revenue and margin assumptions die when capacity, scrap, or service levels are misstated.
Exposes key-person risk
If one plant manager holds the process in their head, you bought tribal knowledge — not a system.
Prices integration work
Broken SOPs, dual ERP, and weak QA become real CapEx and OpEx after close.
Surfaces scalability
A 20% growth plan is fiction if the bottleneck is a single line or a burned-out ops team.
7 workstreams of operational due diligence
1. Facilities, footprint & capacity
Map sites, leases, utilization, shift patterns, bottleneck equipment, and expansion headroom. Single-site concentration is often a silent deal-killer for manufacturing and logistics targets.
2. Processes & documentation
Look for written SOPs, process owners, change control, and evidence that the process is followed — not just laminated and ignored. Tribal knowledge is transfer risk.
3. Quality systems & customer outcomes
Track scrap, rework, returns, complaint rates, CAPA closure, certifications (ISO, industry-specific), and major quality events. Public recalls and litigation leave trails.
4. Supply chain & inventory
Single-source critical inputs, geographic concentration, lead times, safety stock policy, and supplier financial fragility all convert into production risk.
5. People & operating leadership
Span of control, turnover on the floor and in supervisors, union dynamics where relevant, overtime dependence, and succession for the COO / VP Ops / plant managers.
6. Systems & data that run ops
ERP/MES/WMS/CRM maturity, spreadsheet islands, data integrity for inventory and production, and whether management dashboards match reality.
7. Scalability & continuous improvement
Lean maturity, bottleneck economics, CapEx needed for growth, and whether improvement is cultural or consultant theater.
Screen 10 targets for the cost of one ops consultant day
Traditional operational diligence often runs $75,000–$250,000. A structured public-info first pass from dodilligence.io is $49 — enough to kill weak targets before you burn diligence budget.

| Dimension | Traditional ODD | Structured first-pass |
|---|---|---|
| Timeline | 3–8 weeks | Minutes to 48 hours for public-info screen |
| Cost (mid-market) | $75K–$250K+ | From $49 for screening report |
| Site visits | Usually yes | No — confirmatory phase later |
| Best use | Post-LOI confirmatory | Pre-LOI kill / prioritize shortlist |
| Sources | Mgmt, floor, systems, suppliers | Public records, filings, news, facilities, litigation, certifications |
| Output | Full ops report + findings log | Risk register + open questions for mgmt |
Use first-pass operational screening to decide which targets deserve expensive site-based diligence. Use full ODD to confirm and price the workplan.
Deal-killing operational red flags
| Signal | Severity | Why it matters |
|---|---|---|
| Single production site / warehouse | Deal-Killer | Fire, lease loss, or labor strike stops revenue |
| Key process only in one person’s head | Deal-Killer | Transfer failure after founder / plant manager exits |
| Utilization >90% with growth plan | High | Model assumes volume the plant cannot make |
| High scrap / rework / RMA rates | High | Margin erosion + brand risk |
| Single-source critical BOM items | High | Supplier shock becomes production stoppage |
| OT-driven labor model | Watch | Fatigue, safety, and hidden true capacity cost |
| Spreadsheet ERP for inventory | Watch | Working capital and COGS surprises |
| No documented change control | Watch | Quality drift after process tweaks |

How operational DD fits the deal timeline
- Screening / pre-LOI: public footprint, quality events, litigation, capacity signals, management questions. Kill weak targets cheaply.
- LOI: lock access rights for plant tours, systems demos, and supplier intros.
- Confirmatory: site visits, process walks, sample transactions, inventory counts, interviews.
- Negotiation: price in CapEx, quality reserves, earnouts tied to operational KPIs, or walk.
- Close & 100 days: stabilize people, document tribal processes, dual-source critical inputs, fix data integrity.
