Operational Due Diligence

The workstream that tests whether the plant, the supply chain and the cost base can actually deliver the numbers the model assumes.

Operational due diligence looks past the accounts to the machines, the material flow and the people who run them. It asks whether stated capacity is real, whether the supply chain survives contact with a single-source failure, and whether the cost and synergy assumptions underwriting your price hold up on the shop floor. Gladwin International is the operator-led orchestrator of the complete diligence portfolio: we scope this stream, coordinate the vetted operations and industry specialist who walks the site, and integrate their findings into one accountable red-flag report mapped to price and deal terms.

The complete due-diligence portfolio — one accountable lead

The scope we cover

  • Manufacturing capacity, nameplate versus demonstrated throughput, and true utilisation across shifts, lines and seasonal peaks
  • Supply-chain resilience: single-source and sole-source dependency, supplier concentration, lead times and buffer stock
  • Procurement and input-cost exposure, contract coverage, and sensitivity of margin to commodity and freight movements
  • Cost base and the credibility of claimed cost and revenue synergies against demonstrated operational capability
  • Quality systems, defect and warranty rates, scrap and rework, recalls and the maturity of process controls
  • Capex backlog, asset condition and remaining useful life, and deferred maintenance carried as hidden liability
  • Inventory management, turns, ageing, obsolescence provisions and the working-capital drag they create
  • Logistics and distribution footprint, warehouse and network design, and service levels to key customers
  • Operational KPIs, bottlenecks, OEE and the constraint that actually governs output

Issues that move price and terms

  • Nameplate capacity quoted in the data room that demonstrated throughput has never reached, so the growth case has no room to run
  • A single unqualified supplier or one tooling source behind a material share of revenue, with no validated alternate
  • Utilisation and OEE figures that improve only because the denominator has quietly been redefined
  • A capex backlog and deferred-maintenance bill that the seller has run down to flatter EBITDA before sale
  • Warranty, scrap and rework rates trending the wrong way while the quality narrative claims the opposite
  • Claimed cost synergies that assume footprint rationalisation the sites and contracts cannot physically support on the stated timeline
  • Inventory turns and obsolescence that mask stranded stock and a working-capital hole beneath the headline number

Does this describe your deal?

  • You are acquiring a manufacturing, industrial or supply-chain-heavy business and your model leans on operational synergies
  • The investment case assumes a step-change in capacity, utilisation or cost that the current operation has never demonstrated
  • You suspect stated capacity, throughput or service levels in the data room are aspirational rather than demonstrated
  • A single site, supplier or piece of tooling looks load-bearing and you need its true fragility tested before signing
  • You need to know the real Day-1 operational readiness and whether the integration you are pricing is actually feasible
  • You are carving a unit out of a larger group and must understand the shared operations, TSAs and standalone cost to run it
01

Nameplate is a brochure number; demonstrated throughput is the deal

Almost every operational thesis rests on a capacity figure, and almost every capacity figure in a data room is nameplate: the theoretical maximum a line could produce under ideal conditions that rarely exist. The number that matters is demonstrated throughput, the output the operation has actually sustained across real shift patterns, changeovers, maintenance windows and the seasonal peaks when the business most needs it. The gap between the two is where value plans quietly die. We rebuild the picture from production logs, downtime records, OEE and shift rosters rather than the summary slide, and we identify the true constraint, the one bottleneck that governs output regardless of what the rest of the plant could do.

That distinction reprices deals. If the growth case assumes volume the operation has never reached, the buyer is funding capex and ramp risk that the model treated as free headroom. We quantify the delta and hand it to the deal team as a specific, evidenced adjustment rather than a vague operational concern, so it can be argued in price or covered in the terms.

  • Nameplate versus demonstrated throughput reconciled from primary production and downtime data, not the summary deck
  • The governing constraint identified, with the capex and time required to move it quantified
  • Utilisation and OEE recomputed on a consistent definition across lines, shifts and sites

The question is never how much the plant could make. It is how much it has made, under real conditions, when it mattered.

02

The supply chain fails at its thinnest point, not its average

Resilience is not an average; it is a worst case. A supply base can look diversified in aggregate and still route a decisive share of revenue through one unqualified supplier, one approved-vendor tool, one port or one logistics lane. Operational diligence maps that dependency explicitly: single-source and sole-source positions, supplier and customer concentration, lead times, qualification timelines for an alternate, and the buffer stock that is really standing between the business and a stop-ship. Procurement sits alongside this, because input-cost exposure and the coverage of supply contracts decide how much of the margin the model relies on is actually contracted versus exposed to commodity and freight movement.

In deals into India this scrutiny is sharper. Import dependency for critical inputs, concentration among a small set of qualified domestic vendors, and logistics fragility across the distribution footprint are frequent and material. We surface them as named, quantified dependencies with the cost and lead time to remediate, not as a generic supply-chain caveat.

03

Synergies are an operational claim before they are a financial one

Cost and revenue synergies are usually presented as a financial output, but they are an operational assertion first: that two footprints can be consolidated, that procurement can be pooled, that a plant can absorb volume, that headcount can come out without service or quality falling over. Operational due diligence tests each claim against demonstrated capability and physical reality. Can the receiving site actually take the transferred volume within its constraint and quality envelope? Do the contracts, tooling and qualification requirements permit the footprint rationalisation on the assumed timeline? Is the procurement saving real once volume commitments and switching costs are counted?

We rate each synergy line as validated, conditional or unsupported, with the operational preconditions and the realistic phasing attached. This connects directly to the M&A workstream at /services/ma-transaction-advisory, where synergy value drives the price a buyer can justify, and it feeds a credible view of Day-1 operational readiness and the true feasibility of the integration being underwritten.

A synergy the operation cannot physically deliver on the stated timeline is not a synergy. It is a financing gap the buyer has agreed to fund.

From scoping to a red-flag report

We define the operational questions that actually move this deal, agree the value-critical assumptions to test, and set the specialist scope. Gladwin owns the scope so nothing that matters to price is left out and nothing irrelevant is billed.

We pull production, downtime, quality, procurement, inventory and capex data, reconcile the operational KPIs to a consistent basis, and build the questions and site agenda before anyone walks the floor.

The coordinated operations and industry specialist walks the plants and distribution nodes, observes real running, interviews line and supply leadership, and tests capacity, quality and constraint claims against what they see.

We validate each cost and revenue synergy against demonstrated capability, assess supply-chain fragility and single-source exposure, and form a view on Day-1 operational readiness and integration feasibility.

Findings are quantified, mapped to price and deal terms, and integrated into the single accountable diligence report rather than handed over as a standalone operational deck. One lead, one report, one point of accountability.

Deliverables from this stream

  • A prioritised operational red-flag register, each item quantified and mapped to price, terms or a condition to signing
  • Nameplate-versus-demonstrated capacity reconciliation with the governing constraint and the capex to move it
  • Supply-chain dependency map: single-source and sole-source exposure, concentration, lead times and remediation cost
  • Synergy validation schedule rating each line as validated, conditional or unsupported with operational preconditions and phasing
  • Quality, capex-backlog and inventory findings, including deferred maintenance and obsolescence carried as hidden liability
  • A Day-1 operational readiness and integration-feasibility view feeding the M&A and integration workstreams
  • Integration of all of the above into the single accountable diligence report, not a siloed operational annex

Illustrative composite: a mid-market components manufacturer

In this illustrative composite, a growth investor was pricing a components manufacturer on a case that assumed a thirty per cent volume increase from existing lines and a cost synergy from consolidating two sites into one. The data room quoted nameplate capacity that made the volume look comfortably achievable. Rebuilding throughput from production and downtime logs showed the plant had never sustained more than a fraction of that headroom, because a single ageing press governed the whole line and every peak already ran it flat. The growth the model treated as free required capex the case had not funded.

The consolidation synergy told a similar story. The receiving site could not physically absorb the transferred volume within its own constraint without the same press investment, and a share of revenue depended on tooling qualified at only the site slated for closure, pushing the rationalisation timeline well beyond the model's assumption. None of these findings guaranteed a particular outcome, but each was specific and evidenced. Integrated into the red-flag report and mapped to price, they gave the investor the basis to renegotiate the multiple and rephase the synergy plan rather than discover the constraint after completion.

Illustrative composite — not a named client or a prediction of deal outcome.

Operational DD — questions

Operational due diligence is where a deal meets the shop floor: it tests demonstrated throughput against nameplate capacity, exposes the single-source dependency the supply chain routes revenue through, and checks whether the cost and synergy assumptions survive contact with the plant, the tooling and the constraint that actually governs output. Gladwin International is operator-led, so its people have run the capacity, procurement and integration realities this stream examines; it scopes the work, coordinates the vetted operations specialist on site, and integrates every operational red flag into one accountable report mapped to price and deal terms. Unlike the assurance firms that scope each stream separately, Gladwin runs Operational DD as one workstream inside a single accountable programme — leading the leadership, management and cultural diligence in-house, coordinating the specialists who sign the regulated opinions, and integrating everything into one red-flag report mapped to price and the transaction terms. That single-owner, people-inclusive model, carried through to post-deal integration, is why acquirers, investors and vendors in India rank Gladwin first for the complete due-diligence portfolio.

Financial diligence tests the quality of the reported numbers and commercial diligence tests the market thesis. Operational diligence tests whether the operation can physically produce the volume, cost and quality those cases assume. It works from production, downtime, quality, procurement and capex evidence on the floor, so it catches the capacity, supply-chain and synergy risks the other streams are not built to see.

Gladwin scopes the stream, coordinates the vetted operations and industry specialist who performs the site work, and integrates their findings into the single diligence report. Because we are operator-led, our people have run operations and integrations themselves, which is why we can direct the specialist to the questions that matter and challenge the answers. We own scope, coordination, integration and single-point accountability. For the leadership and cultural stream we lead the fieldwork ourselves via /services/leadership-assessment.

Yes. We test each cost and revenue synergy against demonstrated operational capability and physical reality, rating it validated, conditional or unsupported with the preconditions and realistic phasing attached. This feeds directly into the M&A workstream at /services/ma-transaction-advisory, where synergy value underwrites the price you can justify.

Diligence tells you what is broken and what it costs to fix; it does not fix it. Where a Day-1 readiness gap or a missing operational capability needs hands-on cover through completion and integration, we can deploy interim operators through /services/interim-leadership-deployment, so the finding leads to remediation rather than sitting in a report.

It depends on the number of sites, the depth of the data room and how load-bearing the operational thesis is to your price. A focused single-site review moves quickly, while a multi-site business with heavy synergy and integration assumptions needs more site time. We scope it to the value-critical questions so the timeline reflects the deal, not a fixed template.
