Pierre von Rohn — The Independent Expert

6 oktober 2026 · Storage Stories

There is a particular kind of independence that organisations value enormously. The independent consultant has no permanent allegiance, carries no corporate history and is supposedly free to judge each problem on its merits. This makes him especially attractive when technical decisions are difficult, suppliers disagree and management would prefer an opinion that appears to have arrived from somewhere outside the conflict. Independence, in this sense, is less a personality trait than an organisational instrument. It reassures everybody that the judgement belongs to the problem rather than to one of the people competing to define it.

A project manager I will call Pierre von Rohn had spent much of his career in precisely this useful position. Pierre was a freelancer. Companies changed, projects changed and organisations changed, while Pierre retained the attractive mobility of somebody who technically belonged to none of them. He could arrive at a refinery, terminal or engineering organisation without bringing an obvious corporate flag with him. On paper, this created the conditions for unusually objective judgement.

The curious part was that one relationship seemed considerably less mobile.

Where Pierre appeared, a man I have previously called Mr VAM had an unusual tendency to be somewhere in the commercial landscape. Sometimes the connection was direct, sometimes through products, sometimes through technical opinion and sometimes simply through a supplier who Pierre already knew and trusted. The legal and contractual relationships could vary considerably. The practical result often seemed more familiar.

This does not prove that Pierre was acting on instructions from Mr VAM. It would be a mistake to convert repeated proximity into agency without evidence of agency. People in specialist industries repeatedly meet the same people because the industry itself is small, and professionals naturally return to suppliers whose products they know. Experience creates preference, preference creates repetition and repetition can easily look conspiratorial to anyone standing on the wrong side of it.

That explanation deserves to be taken seriously. It also leaves an interesting organisational problem.

A genuinely independent specialist is expected to bring previous experience into a new assignment. That is one of the reasons for hiring him. If Pierre has previously used a particular supplier successfully, it would be irrational to demand that he forget the experience simply to demonstrate independence. If he respects Mr VAM’s technical judgement after many years in the industry, there is equally nothing unusual in consulting it again. Independence cannot sensibly mean intellectual amnesia.

The difficulty begins when experience ceases merely to inform judgement and begins to determine where the burden of proof is placed.

A familiar supplier arrives carrying history. Its products have been seen before, its explanations sound familiar and its people already speak the same technical language as the project manager. A less familiar supplier starts somewhere else. Its product has to be understood, its claims checked, its differences explained and its departures from established practice justified. This can happen without anybody consciously favouring one party. Familiarity simply receives the benefit of accumulated context while novelty receives the burden of explanation.

Pierre appeared particularly effective in this environment. He could be exacting, persistent and difficult to satisfy, qualities that can be enormously valuable in a project manager. Suppliers discovered that apparently minor questions could develop into extended discussions, qualifications and requests for further proof. Technical positions that seemed straightforward when a project began could become unexpectedly complicated once Pierre started examining them.

For those on the receiving end, this could make life remarkably unpleasant. That in itself is not evidence of poor project management. Project managers are not employed to make suppliers comfortable. A good one should challenge assumptions, expose weaknesses and refuse to accept convenient answers simply because a contractor would like the meeting to end.

The more interesting observation concerned where this scepticism seemed to relax.

Mr VAM’s products entered with something other products had to earn: familiarity. His judgement carried the accumulated credibility of a relationship rather than merely the contents of the current datasheet. Pierre did not need to begin from first principles because, in an important sense, the examination had taken place years earlier. Other suppliers could find themselves defending a particular detail while Mr VAM benefited from an entire history of previous conversations that was invisible to everyone else in the room.

This creates a peculiar form of asymmetry because every individual decision can remain defensible. Pierre can explain why he asked the question. The unfamiliar supplier genuinely did need to demonstrate its design. Mr VAM’s product genuinely had been used previously. The technical concern genuinely could have mattered. Nothing requires corruption, instruction or even conscious favouritism. Yet after enough decisions, one supplier may consistently receive the benefit of context while others receive the discipline of evidence.

Freelancing makes this especially difficult to recognise. If Pierre were permanently employed by Mr VAM, everybody would immediately understand the relationship and adjust for it. If he were a sales representative, his preferences would be expected. Independence changes the meaning of precisely the same behaviour. Recommendations acquire the authority of professional judgement because they appear to come from somebody who has no commercial reason to make them.

That is the extraordinary value of the independent expert. He does not have to sell anything. He merely has to find one solution more convincing than another.

The distinction matters because modern organisations outsource increasing amounts of judgement. Engineering companies employ consultants, owners employ project managers and project managers seek advice from specialists. Each layer appears to increase independence because responsibility is distributed among separate professional parties. In practice, however, people remain connected through histories that do not appear on an organisation chart.

Pierre could therefore change employer without necessarily changing ecosystem. The business card changed more easily than the trusted relationships behind it. A new client might reasonably believe it had hired an independent project manager, while Pierre quite reasonably continued relying on the technical people and suppliers whose competence he already trusted. From Pierre’s perspective there need be no contradiction at all.

From the perspective of a competing supplier, the experience could feel rather different.

The supplier believes it is entering a technical evaluation. It prepares calculations, references, drawings and explanations. It assumes that success depends upon demonstrating that its solution satisfies the requirements. Gradually it discovers that the real benchmark is not merely the written specification but a body of accumulated assumptions that existed before it entered the room.

Those assumptions are difficult to challenge because they are rarely presented as assumptions. They appear as experience.

“This is how we normally do it” is an extraordinarily efficient technical argument because it sounds empirical rather than preferential. “I have never seen a problem with this solution” is stronger still, because the absence of a remembered failure becomes evidence of reliability. When the familiar supplier speaks, previous experience fills the gaps. When the unfamiliar one speaks, gaps become questions.

A capable project manager can make this process almost impossible to criticise because every challenge remains technically plausible. More calculations can always be requested. Another reference can always be useful. A weld can always be inspected more closely. A design detail can always deserve further explanation. The engineering world contains an effectively unlimited supply of reasonable questions.

The secret is therefore not to reject the competing supplier. Rejection would create a decision that could be challenged. Continued examination is considerably more sophisticated.

A supplier can spend weeks answering questions without ever being formally excluded. A design can remain “under review.” A concern can require “some additional clarification.” Another participant may need to be consulted. Eventually programme pressure begins to matter, and the solution already understood by the project organisation acquires an additional advantage simply because everybody knows how to proceed with it.

Nobody has selected the familiar supplier unfairly. Time has selected it.

This may explain why Pierre seemed capable of making other people’s lives miserable while remaining professionally defensible. Irritation is not a procurement category. A supplier cannot formally complain that the project manager asks too many intelligent questions. It cannot easily object that another man’s opinion appears to carry disproportionate weight when every individual instance can be explained as the exercise of experience.

The elegant part is that Mr VAM need not even be present.

Influence is normally imagined too literally. We look for instructions, secret agreements or direct intervention because those produce evidence. Professional ecosystems work more quietly. If Pierre already trusts Mr VAM, understands his products and shares many of his technical assumptions, then Mr VAM’s worldview can enter a project without Mr VAM entering the meeting.

There is no need to telephone the principal before every decision. A sufficiently durable professional relationship eventually makes consultation unnecessary because the relevant preferences have already become part of judgement.

This creates what might be called portable alignment. Pierre can move from one organisation to another while carrying with him a stable hierarchy of people, products and opinions he considers reliable. His contractual independence remains entirely genuine. His intellectual independence may be more complicated, although that complication is hardly unique to him. Every experienced professional carries a portable hierarchy of trust.

The organisational mistake is to confuse the absence of employment with the absence of allegiance.

Allegiance need not be financial and need not even be consciously experienced as allegiance. It can simply be confidence accumulated over many years. We trust some people before they speak and require others to persuade us. Once that distinction becomes established, an allegedly neutral technical comparison begins with the participants standing at different distances from the finish line.

Pierre von Rohn is therefore not interesting because he was a freelancer who liked one particular supplier. Industries are full of people who have favourite suppliers. He becomes interesting because the same independence that gave his judgement authority also made the persistence of that preference less visible.

Where an employee recommends his employer’s product, everyone can see the conflict and discount the recommendation accordingly. Where an independent project manager repeatedly prefers the product of a long-standing associate, the same preference arrives wearing a considerably more respectable uniform: professional experience.

The distinction becomes even more useful when Mr VAM himself has become controversial. A client may hesitate to appoint Mr VAM directly, or may simply have no reason to involve him. Pierre does not bring Mr VAM into the organisation. He brings a judgement system within which Mr VAM already occupies a privileged position.

Again, this does not require instruction. Indeed, instruction would make the arrangement less efficient because it would create something that could later be demonstrated. The strongest professional networks are precisely those in which nobody needs to tell anybody what to think.

The pattern then reproduces itself through ordinary project decisions. Pierre arrives. A technical question arises. Mr VAM’s product is familiar. His opinion is respected. Alternative suppliers discover additional questions. Pierre remains independent throughout.

There is something almost admirable about the efficiency.

Organisations spend considerable amounts of money trying to secure independent expertise because they understand that permanent employees can become trapped by internal assumptions. They bring in somebody from outside to challenge the system. What they sometimes forget is that the outsider arrives with a system of his own.

Pierre’s system just happened to be unusually portable.

Over enough projects, this creates the appearance that Mr VAM is everywhere. He need not be. His products can travel without him, his technical preferences can travel through people who trust him and his reputation can enter organisations in advance of any formal commercial relationship. A conventional salesman can reach only the meetings he attends. A trusted independent project manager can carry the same preference into meetings where the salesman would never have been invited.

This is a considerably better distribution model.

It is also almost impossible to attack without making oneself look unreasonable. Question Pierre’s independence and he can point correctly to the absence of an employment relationship. Question the preferred product and the discussion returns to technical detail. Question the repeated appearance of Mr VAM and the specialist nature of the industry provides an entirely plausible explanation.

Every answer works.

The person experiencing the cumulative effect is left with the least useful argument of all: the pattern.

Patterns are awkward because organisations prefer individual decisions. Each procurement has its reasons, each technical rejection has its calculations and each project manager has professional discretion. Place the events beside one another and something may become visible, but administrative systems have little appetite for conclusions that exist primarily between files.

Pierre therefore belongs naturally in the same world as Mr VAM, although for a different reason. Mr VAM’s talent was to ensure that individual facts did not easily become one conclusion. Pierre’s professional mobility illustrates the complementary possibility: one influence can appear in many organisations without ever becoming one formal relationship.

The first depends on separation of evidence. The second depends on separation of contracts.

Both benefit from the same organisational instinct. We judge what is written down more readily than what persists between documents, companies and people.

Perhaps Pierre was entirely independent. Perhaps he simply knew whose judgement he trusted and saw no reason to rediscover the same answer for every new employer. There is nothing inherently wrong with that. Indeed, much of expertise consists precisely of knowing whose expertise deserves to be trusted.

The more difficult question is what remains of independence when the employer changes repeatedly but the preferred source of truth does not.

For the organisation hiring Pierre, the answer may matter more than whether anybody can prove a formal conflict. An independent expert does not become valuable merely because nobody pays him from the wrong company. His value lies in bringing genuinely independent judgement to the organisation paying him now.

Pierre von Rohn’s career presents a useful reminder that these are not necessarily the same thing.

A freelancer can be independent of every employer while remaining remarkably loyal to an ecosystem.

And once that happens, the principal does not need to follow him from project to project.

He is already there.
