Operational Due Diligence: Can the Business Deliver Its Plan?

An acquisition model may assume higher output, shorter delivery times and lower costs. Those improvements depend on production capacity, people, systems and resources that need to be verified.

Operational due diligence tests whether the business can deliver the performance behind the investment case. It examines how work actually moves through the company, where constraints appear and what the buyer must fund or change after completion.

Key takeaways

• Operational due diligence assesses execution: whether the company’s resources and processes can sustain current performance and support the proposed plan.
• Installed capacity, completed production and customer-ready output are different measures.
• Growth and cost-saving assumptions need evidence of timing, investment requirements and implementation capacity.
• Dependencies on individuals, systems, facilities or external providers can change what the buyer acquires.
• Findings should identify the operational consequence, required action, cost assumptions and responsible owner.

What Is Operational Due Diligence?

Operational due diligence, or ODD, examines how a company produces goods or delivers services. It assesses the operating model, performance, constraints and changes required to achieve the transaction’s objectives.

For an acquisition, the review may test whether the target can operate independently after completion. For a growth investment, it may examine whether the company can increase output without disproportionate spending or deteriorating quality.

This guide concerns operating companies. Operational reviews of fund managers involve a different scope.

How Does ODD Fit Into the Wider Transaction Review?

Commercial due diligence examines the market and revenue opportunity. Financial due diligence assesses reported performance, earnings quality and cash-related risks. Operational due diligence tests the resources and processes needed to execute the plan.

These workstreams should use consistent assumptions. A forecast cannot depend on faster delivery if the operating review identifies an unresolved production bottleneck.

The broader M&A due diligence checklist coordinates these disciplines. ODD investigates the operational assumptions in greater depth rather than repeating the entire acquisition review.

Operational Due Diligence Checklist: Six Areas to Test

1. Trace the Operating Model From Order to Delivery

Start with how the business fulfils a customer commitment.

Map the main stages: order acceptance, planning, procurement, production or service delivery, quality checks, dispatch and customer acceptance. Identify the people, systems and external parties responsible for each handover.

Then compare the documented process with actual records. Workarounds, repeated approvals and manual corrections may explain delays that do not appear in management’s process diagrams.

Use representative samples. A successful demonstration order does not establish how the company handles ordinary volumes, peak demand or difficult product variants.

2. Establish Sustainable Capacity

Distinguish theoretical capacity from demonstrated output.

Equipment specifications may describe performance under conditions the business does not consistently achieve. Actual delivery also depends on staffing, maintenance, changeovers, material availability and downstream processing.

Examine the constraint that limits the whole process. Additional assembly capacity will not increase customer-ready output if testing or packaging remains the bottleneck.

Assess the relevant product mix and operating period. A short production run or exceptional month should not become the baseline without explaining what made it possible.

3. Test Quality and Delivery Performance

High activity does not necessarily produce acceptable output.

Examine rejection rates, rework, returns, warranty claims, missed delivery dates and customer acceptance records. Check how management defines each metric and whether those definitions remain consistent across reporting periods.

For example, a reported delivery date may refer to dispatch rather than receipt or acceptance. A production figure may include items awaiting inspection.

Identify where quality failures create additional labour, material consumption or delivery pressure. These consequences should feed into the financial assessment rather than remain isolated operational observations.

4. Challenge Growth and Cost-Saving Assumptions

A plan to increase output should explain what must change.

Identify the equipment, recruitment, training, facilities, systems and working capital required. Examine implementation lead times and whether the business can absorb the changes while maintaining current delivery.

Apply the same discipline to savings. Lower purchasing costs may depend on volumes not yet secured. Reduced headcount may assume automation that has not been installed or tested.

Separate demonstrated improvements from proposals. Record who will implement each change, what it will cost and which assumptions could delay the benefit.

5. Identify Hidden Dependencies

Look beyond the organisation chart and supplier list.

A business may depend on one employee’s undocumented knowledge, a founder’s customer relationships or systems administered by an external contractor. Several apparently independent suppliers may rely on the same upstream producer.

Where a critical counterparty creates uncertainty, use third-party due diligence to investigate the company, ownership and relevant risk signals behind the relationship.

Operational assessment should establish the consequence of that dependency and the practicality of replacement. If a software product is central to delivery, a separate software due diligence review should examine its technical condition. ODD should incorporate the implications without attempting to substitute for that specialist work.

6. Test Readiness for Completion and Disruption

Establish what changes when ownership changes.

A business sold out of a larger group may rely on shared finance staff, IT systems, purchasing arrangements, premises or insurance. Identify what remains available, for how long and at what cost.

Review continuity arrangements against specific scenarios. A written recovery plan does not establish that replacement equipment, alternative premises or restored systems will work within the required time.

Ask for evidence of exercises, incidents and corrective actions. Legal and technical specialists should assess the relevant contractual rights and recovery capabilities.

Which Records Should the Review Examine?

The evidence request should follow the transaction’s operational questions.

Useful records may include:

• production, scheduling and service-delivery logs;
• quality, rework, returns and customer-acceptance records;
• maintenance history, downtime and equipment availability;
• staffing, shift patterns and critical-role coverage;
• inventory, procurement and supplier-performance records;
• operating budgets, capital expenditure plans and implementation schedules;
• system dependencies, incident records and recovery-test results;
• shared-service arrangements and separation plans.

Request periods that capture normal trading, peaks and relevant changes. Record missing data and inconsistencies rather than treating a complete data room as proof of reliable operations.

The Saleable Output Test: Follow One Production Cohort

Consider a hypothetical manufacturer reporting 1,000 completed units from one production cohort.

Records for that same cohort show:

• 1,000 units completed assembly;
• 700 underwent final inspection by the reporting date;
• 630 passed inspection;
• 300 awaited inspection;
• 70 failed inspection and required further disposition.

The headline figure describes assembly completion. It does not establish that 1,000 units were ready for customers.

The review should investigate the inspection queue, the reasons for failure and the time needed to resolve outstanding units. It should also establish whether the forecast uses assembled, inspected or accepted output.

This example does not prove that sustainable monthly capacity is 630 units. That requires evidence across appropriate periods, product mixes and operating conditions. It demonstrates why the definition behind a capacity claim matters.

For a service business, apply the same test to completed tasks, resolved cases and customer-accepted work. Activity recorded in a system may not represent a fulfilled customer obligation.

Turn Findings Into Investment Decisions

An ODD report should explain what the findings change.

A bottleneck may require additional investment before forecast revenue is achievable. Undocumented processes may create a transition risk if key employees leave. Shared systems may introduce separation costs absent from the acquisition model.

For each material finding, record:

• the claim being tested and the supporting evidence;
• the operational consequence;
• the proposed response;
• estimated cost and timing, with assumptions;
• the responsible owner;
• what must happen before completion or after acquisition.

Separate recurring costs from one-off investment. Distinguish realistic improvement opportunities from benefits that depend on untested assumptions.

The investment team can then assess whether to revise the plan, investigate further, negotiate protections or reconsider the transaction.

How Molfar Intelligence Contributes to Operational Due Diligence

Molfar Intelligence adds an investigative layer where operational claims depend on facts outside the seller’s reporting.

Our due diligence services investigate companies, ownership, affiliations, counterparties and material risk signals. This work can help identify undisclosed relationships or external exposure affecting the proposed operating model.

Reporting separates documented findings from indicators and unresolved questions. Engineering assessments, capacity validation, financial modelling and specialist compliance reviews should involve the relevant qualified professionals.

To scope the investigation, identify the operating claims that matter to the investment decision and which parts require independent verification.

FAQ

What should operational due diligence cover before buying a manufacturing company?

Examine the order-to-delivery process, demonstrated capacity, quality, maintenance, staffing and critical dependencies. Test the investment required to meet the buyer’s plan. Distinguish installed equipment from sustainable, customer-ready output, and identify what changes after the business leaves its current ownership structure.

How is operational due diligence different from financial due diligence in an acquisition?

Financial due diligence assesses matters such as reported earnings, cash conversion and working capital. ODD examines the operational drivers behind those results and forecasts. It may identify bottlenecks, underinvestment or transition costs that financial advisers need to incorporate into their assessment.

How can I assess operational risk when the target has incomplete production or service records?

Cross-check available logs, customer records, invoices, staffing information and other relevant evidence. Use interviews and specialist observations where appropriate. Define the gaps and their consequences. Missing records limit confidence; they do not justify inventing a performance baseline or assuming management’s forecast is verified.

How should operational due diligence findings inform the first 100 days after acquisition?

Translate findings into prioritised actions with owners, budgets and dependencies. Address issues threatening immediate delivery before pursuing longer-term efficiencies. Identify which changes require further testing and which benefits should remain outside the base case until the necessary resources and implementation evidence are in place.
