Ask a search engine’s AI how to assess Deployment Readiness in hard tech and it will draw a ladder. Three stages run left to right: lab prototype, system validation, scaled production. Under each sit three bands, one each for technology, manufacturing and investment readiness levels (TRL, MRL and IRL), running from TRL 1–4, MRL 1–4 and IRL 1–3 at the bottom to TRL 8–9, MRL 8–10 and IRL 7–9 at the top. The prose around the ladder is sensible enough. The ladder is wrong.
The columns
Stacking the bands in columns says the three scales advance together. A company at TRL 7 is taken to sit near MRL 7 and to be fundable at the matching investment level. The idea has a respectable origin. The US Department of Defense built manufacturing readiness levels to be assessed alongside technology readiness at the key acquisition milestones, with one programme office holding the money, the design and the production contract. Inside that structure the scales are paced because someone is paid to pace them.
Venture-funded hard tech has no such office. Founders tell the technology story and scientists score it. Making the thing is nobody’s job until a contract manufacturer quotes for it. Capital is priced off the first and discovers the second later. A readiness chart drawn in columns has already assumed the answer to the only question that matters.
The distance
The useful measurement is how far apart the scales sit. Kaipability scores it as the Coupling Gap: the distance between the highest technology gate a company has passed and the manufacturing gate it has demonstrably passed, each on its own rail.
Two back-tests from public record, scored years before the outcome was known, show the shape. One company stood at TRL 7 and at 3 on MCRL, the Manufacturing Capability Readiness Level developed at Rolls-Royce. Its technology had been shown working in the end application, while the route to make it at volume was still at the level of concepts and trials. The gap was four. The other stood at TRL 4 with manufacturing in band 2–3. The gap was small, yet it failed every milestone flagged on its road ahead.
The second case matters as much as the first. A small gap means the story has not yet outrun the making. It says nothing about whether either will move. The investor is shown the TRL. The balance sheet pays for the MRL.
The borrowed letters
The third column carries less weight than it appears to. “IRL” is used for at least two scales. Steve Blank’s Investment Readiness Level, published in 2013 and drawing on data from the US National Science Foundation’s I-Corps programme, measures how thoroughly a team has tested its business model. In systems engineering the same letters mean Integration Readiness Level, the maturity of the interfaces between components. The Commercial Readiness Index used by the Australian Renewable Energy Agency runs to six, not nine. None of these was designed to sit under an MRL.
The manufacturing column runs to ten while the technology column runs to nine, and the ladder sets them side by side as equals. When scales of different lengths are drawn as one, the drawing is doing the measuring.
The cost curve
The same answer promised a cost path from a $50,000 prototype to a $500 production unit, and warned against costs that fall “linearly rather than exponentially”. Manufacturing costs follow neither pattern. They follow Wright’s law: a fixed percentage off for each doubling of cumulative output. At a 20 per cent learning rate, a hundredfold reduction needs about twenty doublings, which is more than a million times the cumulative volume already built.
No hardware start-up waits for that volume. The hundredfold comes from redesign, a change of process or a change of supplier. Each of those resets manufacturing gates the ladder has already ticked. Most of a cost-down is redesign, and every redesign sends the manufacturing score back down the rail.
The rails
The fix is to draw the scales apart. Score each on its own rail, mark where the company actually stands, and show the distance. The chart below draws the same companies both ways. Toggle between the ladder as drawn and the back-tests as found, hover over a ribbon for the detail, and zoom in on the gap.
Back-tests scored by Kaipability from public record. Bands follow the ladder as published. MCRL, the Manufacturing Capability Readiness Level developed at Rolls-Royce (Ward, 2012), runs 1 to 9. Over time is an illustration of the pattern, not a company.
On separate rails the question changes from “what level is this company at?” to “how far has the story run ahead of the making, and is the distance closing?” That question can be answered with evidence, and the answer can be signed.
The work
Manufacturing Engineers score the making apart from the story. They prove a route holds tolerance at rate, with people who did not design it. They cost the redesigns hidden inside a cost-down plan. They freeze the architecture before the tooling is cut, and they qualify the second source before the first one fails.
Kaipability works at this interface. It measures the distance between what a company can demonstrate and what it can make, and puts a name to the score. Investors and founders who want that distance measured before it is priced can start the conversation below.
If you are pricing a company off its technology level, that is the conversation to have.
