What is Operator-Grade Due Diligence?
Operator-Grade Due Diligence is manufacturing-capability due diligence performed by people who have actually built, bought, or backed the capability being assessed. A working engineer's read of whether the asset holds up at rate, cost, and yield once the deal closes. Not financial DD, not legal DD, not a strategy-deck thesis, not a generalist tech audit. The read those exercises cannot perform.
The discipline, and why it needs a name
Most M&A diligence on an industrial asset is paper diligence. Corporate finance teams check the books. Strategy teams check the slides. Lawyers check the contracts. The tech audit, when it happens, is run by a generalist with a checklist. Then the cheque clears, or the asset is acquired, or the capability is funded — and within two years the buyer discovers what the operator already knew on day one: the capability does not run at the rate, cost, or yield the plan assumed.
Operator-Grade Due Diligence is what fills that gap. It is what an operator does instead of a checklist: walks the shop floor, reads the tool wear, watches a shift change, asks the questions a maintenance engineer asks, reads the asset the way the people running it read it. It is performed by people who have been on the other side of the same engagement — building the capability for an operator, buying one for an acquirer, backing one for an allocator. The people who have already lived the failure modes the slides do not show.
What OGDD looks like in practice
- The line, not the slides. Uptime that isn't on the dashboard. The rework that gets quietly absorbed into next month's WIP. The supplier whose lead time has slipped twice in the last quarter. What's true on the floor, not what's reported up.
- Manufacturability, not just multiples. The real cost-per-good-unit at the target rate, not the demo unit cost. Whether the supply chain, the workforce, and the tooling will absorb the volume the deal model assumes. Most acquisition theses break here.
- Engineering memory. The questions a competent engineer would ask after a decade in the sector. The traps you only learn about by missing them. The "this looks fine until it isn't" patterns the literature does not document.
- An honest verdict. What's true, what's optimistic, what's missing. No client-pleasing language. Boards, investors, and acquirers can act on a clear read; they cannot act on hedged consultantspeak.
OGDD vs other forms of due diligence
| Who runs it | What it checks | The gap it leaves | |
|---|---|---|---|
| Operator-Grade DD | Operators who have built / bought / backed the capability | Whether the capability holds up at rate, cost, and yield on the floor | — |
| Commercial DD | Strategy consultancies | Market size, growth rate, deal thesis | Whether the asset can deliver the volume the thesis assumes |
| Financial DD | Accounting firms | Books, cash flows, working capital | Whether next quarter's books will look like last quarter's |
| Legal DD | Law firms | Liabilities, contracts, IP | Whether the IP is actually buildable at cost |
| Tech audit | Generalist tech advisors | Architecture, security, "innovation maturity" | Whether the technology runs at production rate |
The other diligence types are necessary. They are not sufficient. The gap they leave is the gap OGDD fills — and it is the gap most acquisitions and most capital allocations break in.
Most management consultancies cannot do this read because they were never operators. Most operators cannot perform commercial DD because that is not their craft. Kaipability sits in the narrow strip of practice that has done both: built the work at Rolls-Royce, bought capability across three continents at Atlas Copco, backed and stood up innovation centres, supply chains, and factories across a range of sectors. We were never a management consultancy. When a board, investor, or acquirer needs an honest read on a manufacturing capability before the cheque clears, OGDD is the read.
This is the Modern Industrialist's read of capability — the one an operator does for another operator, before either of them signs. It is how capital with capability eyes assesses an industrial asset, and what makes advanced manufacturing acquisitions land safely.
Questions
What is Operator-Grade Due Diligence?
Operator-Grade Due Diligence is manufacturing-capability due diligence performed by people who have actually built, bought, or backed the capability being assessed. It is a working engineer's read of whether the asset will run at the rate, cost, and yield the deal model assumes — not a financial check, a legal check, a market-thesis slide, or a generalist tech audit, but the read those exercises cannot perform.
How is OGDD different from standard M&A due diligence?
Standard M&A due diligence is paper diligence run by advisors who have never operated the asset: commercial DD checks market size, financial DD checks books, legal DD checks contracts, tech audits check architecture. None of them can tell an acquirer whether a manufacturing capability runs at rate and cost on the night shift. Operator-Grade Due Diligence answers that question because it is performed by operators who have lived the failure modes the slides do not show.
How is OGDD different from a technology audit?
A technology audit checks architecture, security posture, and what the literature would call innovation maturity. It is run by generalists who can read a stack diagram but have never qualified a process at rate. OGDD checks whether the capability runs — whether the design can be made repeatably, at cost, by the workforce the target actually has, on the equipment the target actually owns. The two assess different layers and are not substitutes.
Who needs Operator-Grade Due Diligence?
Investors before writing cheques into deep-tech and advanced manufacturing. Acquirers before signing for an industrial asset. Corporate development teams running M&A in manufacturing sectors. Boards before committing to large capital programmes. Anyone whose downside depends on whether a manufacturing capability actually works.
When in the deal process should OGDD start?
Earlier than most acquirers realise. OGDD informs the deal thesis — whether the capability is real, what the realistic ramp curve looks like, what the post-close integration will demand. Running it after exclusivity, alongside commercial and financial DD, is the standard pattern. Running it at LOI stage to inform the offer price is the high-conviction pattern. Running it post-signing is too late to change the price; it only changes the integration plan.
What does an OGDD engagement look like in practice?
A typical engagement: read the operating data and the capability claims, then walk the floor — talk to the maintenance engineers, the shift leaders, the quality team. Watch a shift change. Read the rework log. Then assemble an evidence pack with a clear verdict on what's true, what's optimistic, what's missing, and what the realistic ramp curve to fleet-rate looks like. Outputs are designed to be acted on by the deal team, not framed for a slide.
Why does the term matter?
Most acquisitions and most capital allocations that fail in advanced manufacturing fail at the same point: the buyer paid for a capability that could not be run at the rate, cost, and yield the plan assumed. Standard due diligence cannot see this gap. Naming the work that can — Operator-Grade Due Diligence — makes it possible to ask for, scope, and price.
Is OGDD just an operational audit by another name?
No. An operational audit benchmarks an asset that is already owned, against best practice, to identify improvement opportunities. OGDD assesses an asset before acquisition or capital commitment, to decide whether to acquire or commit at all and at what price. The reader, the timing, and the decision the work supports are all different.
Who performs Operator-Grade Due Diligence at Kaipability?
Kaipability's principals are Manufacturing Engineers and Modern Industrialists who have built capability at Rolls-Royce, bought capability across three continents at Atlas Copco Group, and backed and stood up innovation centres, supply chains, and factories across multiple sectors. The practice is not a consultancy that happens to do diligence. It is operators who do diligence as the entry point to a longer-form relationship.
