Chapter 4 - The Materialisation of Expertise in European Infrastructure Advisory

4.1 How European advisory practice constitutes itself

This chapter does the descriptive groundwork on which the framework’s analytical chapters then operate. It describes how expertise is materialised in European infrastructure advisory through what I call the integrated three-scale system: an architecture in which the individual consultant, the firm as knowledge-managing collective, and the domain as public-interest tradition are mutually constitutive. The three scales are not independent layers; they produce one another. The individual is individuated by the firm and by the domain; the firm is individuated by the individuals it forms and by the domain it operates within; the domain is individuated by the firms that work within it and by the content the wider European public-interest tradition reproduces across decades.

The chapter is descriptive, not yet analytical. It does not yet develop the concerns about what AI mediation is doing to the integrated three-scale system; that is the work of Chapters 5 and 7. What this chapter does is establish the system as it has historically operated, so that the subsequent analytical chapters have a ground against which to operate.

The chapter draws on three sources. First, the philosophical framework Chapter 3 assembled - Stiegler on individuation across scales, Polanyi and Collins on tacit and contributory expertise, MacIntyre on practices and internal goods. Second, the institutional architecture Chapter 2 introduced - the ChMC framework and European infrastructure advisory as a distinctive domain. Third, the lived material from my own practice and from observation of colleagues across firms and sectors, marked clearly where it operates.

The chapter works across three scales - individual, organisational, and domain - and concludes with a section on how the three scales are mutually constitutive. The mutual constitution is the framework’s contribution at this point: the integrated three-scale system is not an analytical aggregation of three separate scales but an institutional architecture whose content depends on the integration.

4.2 The individual scale: how a consultant comes into being

The individual scale is the level of the consultant whose professional identity is at stake in the analytical chapters that follow. The framework’s claim is that the consultant is not a static professional persona but an individuation - an ongoing process of becoming a particular kind of practitioner, reproduced through sustained engagement with formative engagements over the arc of a career.

Individual individuation in European infrastructure advisory operates through three components.

The first is formal training. Consultants enter the profession with formal training - degrees in economics, engineering, public policy, urban planning, environmental science, and adjacent disciplines - and continue formal training across the career through certifications, professional development, and the institutional architectures of chartering. The formal training provides what the consultant brings to the engagement at the level of analytical apparatus and disciplinary vocabulary. The framework treats formal training as important but not sufficient; it provides the conditions under which contributory expertise can develop, but contributory expertise itself develops through engagement with consequence rather than through formal training alone.

The second is engagement with consequential work. Consultants develop contributory expertise through sustained engagement with engagements: building tariff models from blank documents and learning from the corrections, drafting memos that fail and producing revised drafts that land, attending regulator meetings and learning what to listen for, presenting to clients and learning when to hold a position and when to retreat. Contributory expertise - in Collins’s sense, the ability to contribute to the practice through embodied engagement - is built through engagement of this kind, not through formal training.

Stockholm, 2018. A young analyst runs a stakeholder mapping workshop for an electricity transmission regulatory engagement. She has prepared the materials, rehearsed the framing, structured the agenda carefully. The workshop produces a clean map: actors sorted by interest and influence, colour-coded, annotated. The partner reviews it after and asks: where is Svenska Kraftnät? The transmission operator does not appear in the engagement scope - it is not directly party to the pricing review - but its infrastructure investment programme constrains every strategic option the client is considering; any recommendation that ignores the investment pipeline is advisory in name only. The analyst had mapped the regulatory space. She had not yet learned that the regulatory space sits inside a physical topology that has its own logic, and that learning to see both simultaneously is what distinguishes an infrastructure regulatory analyst from a regulatory analyst who happens to work on infrastructure. She spends that evening redrafting the map. She has never since produced a stakeholder analysis without asking what the physical network requires.

The framework treats this kind of engagement as formative in the Stieglerian sense: it is the engagement through which the consultant’s individuation as a particular kind of practitioner takes place. The engagement is not generic; it is shaped by the firm the consultant works within (which determines what engagements are available and how supervision operates), by the domain the engagements are in (which determines the content the consultant is engaging with), and by the wider professional tradition the consultant is being formed into.

The third is senior judgment witnessed and absorbed. The consultant’s individuation also operates through witnessing senior practitioners exercising professional judgment - in client meetings, in internal partner discussions, in the moments when senior practice is visible to the more junior practitioner who is being formed. Senior judgment is not always articulable in propositional form; it is partly a matter of what Polanyi calls tacit knowledge, transmitted through engagement with the practice rather than through explicit teaching.

Recent work in cognitive science provides empirical support for the durable character of this component of formation. Oakley et al. [@oakley2025memory] argue that the consolidation of declarative and procedural memory - the systems on which expert judgment depends - requires sustained engagement with the content over time, and that the absorbed schemata built through this consolidation are precisely what enables the practitioner to evaluate, refine, and guide externally available content. The senior judgment that infrastructure advisory practice depends on is, in this reading, not a static information stock but long-consolidated memory systems whose production cannot be shortcut by interactional fluency with external systems.

Brussels, 2020. An advisory team is preparing a formal regulatory challenge on behalf of a Belgian energy client. The commercial case is sound: the numbers support it, the procedural grounds are defensible, the regulatory determination has a genuine weakness the challenge would expose. The senior partner - who has been working with Belgian energy regulators since CREG’s establishment in 1999 - says: not now. He cannot fully articulate why. Something about the transition at the regulator, about a relationship the client cannot afford to damage before the next regulatory period opens, about a signal in the new president’s recent speeches that the team has not registered. The team thinks he is overcautious. Eighteen months later, the new CREG president initiates a sector-wide market investigation that directly affects the client’s revenue stream. The partner had read something in the institutional temperature that existed only in the accumulated residue of two decades of working with that specific institution. It was not in any document. It was not transferable through a briefing. It saved the client a great deal.

The three components together produce the individuation of the individual consultant. The framework treats this individuation as what makes a consultant a consultant in the chartered-status sense: not the formal training alone, not the engagement with consequential work alone, but the integration of all three components across the arc of a career, mediated by the firm and the domain within which the career operates.

The ChMC three-stage architecture - Foundation, Applied, Chartered - is the institutional framework within which this individuation is structured. Foundation stage is where the formative engagements are most concentrated, where the consultant develops the basic tacit-knowledge ground that contributory expertise builds on. Applied stage is where the consultant develops autonomy, where the formative engagements transition from highly supervised to more independent, and where the consultant begins to exercise the professional judgment that Chartered practice will then operate on. Chartered stage is where the professional judgment becomes the consultant’s primary contribution, exercised in the contexts the analytical chapters will then engage.

4.3 The organisational scale: the firm as a knowledge-managing collective

The organisational scale is the level of the firm whose identity as a knowledge-managing collective is at stake in the analytical chapters that follow. The framework treats the consulting firm as constituted by the integrated practices through which its distinctive way of seeing is reproduced across generations of practitioners.

The framework draws on Nonaka and Takeuchi’s SECI model as the structural device for characterising organisational knowledge management in consulting firms. The SECI model identifies four modes through which knowledge moves between tacit and explicit forms across the organisation: Socialisation (tacit to tacit, through shared experience and apprenticeship); Externalisation (tacit to explicit, through articulation into transmissible forms); Combination (explicit to explicit, through recombination of articulated forms); Internalisation (explicit to tacit, through absorption into individual practice). The four modes operate as a continuous spiral through which the firm’s knowledge is reproduced across time.

A mid-sized London advisory firm specialising in regulated infrastructure has a concept it calls “the regulatory clock” - an informal framework for reading where any given regulatory process is in its cycle and what that implies for what can and cannot be moved. It is not in any playbook. It is not on any slide. It lives in the onboarding conversations senior consultants have with junior ones, in the casual annotations partners add to client briefing notes, in the way strategy meetings are opened: where are we in the clock? An analyst joins from a large management consultancy with sophisticated knowledge management systems - databases, playbooks, frameworks for everything. She spends three months confused by the clock’s absence from any document. By month six she is using it instinctively, though she cannot say precisely where she learned it. By year three she is teaching it to someone new, in exactly the kind of onboarding conversation she cannot remember having been in.

The framework’s contribution at this point is to read organisational knowledge management not as productivity-supporting infrastructure but as identity-producing practice. What the firm reproduces through the SECI cycle is not just knowledge that supports productive work; it is the content that makes the firm a particular kind of firm - its distinctive framings, its sectoral instincts, its methodological reflexes, the particular vocabulary in which it recognises a situation, the institutional content of its way of seeing. This is what makes one infrastructure advisory practice distinguishable from another even when they sell similar services.

The framework’s reading is that this identity-producing function of organisational knowledge management has been underrecognised in the existing literature on consulting under AI mediation. The IS-theoretical work, including Tuczek et al., engages organisational knowledge management at the level of productivity and efficiency. The framework engages it at the level of identity - what the firm is as a knowledge-managing collective, and what is at stake when that identity is at risk under contemporary AI mediation.

Firm-distinctive identity operates through several institutional architectures.

Methodologies and frameworks. Consulting firms develop methodological apparatus - analytical frameworks, sectoral playbooks, structured approaches to recurring engagement types - that constitute the firm’s distinctive way of approaching the work. The methodologies are not generic; they bear the marks of the firm that produced them, and the content distinguishes one firm’s analytical voice from another’s.

Case databases and institutional memory. Firms maintain institutional memory of past engagements - case studies, internal documentation, institutional knowledge of which approaches have worked in which contexts. The institutional memory is not just an archive; it is the content through which the firm’s accumulated experience is recirculated to current practitioners and through which Foundation-stage and Applied-stage consultants are formed in the firm’s distinctive way of seeing.

Senior practice and apprenticeship. The firm’s identity is reproduced through the institutional architecture of senior-to-junior transmission. Foundation-stage consultants are formed not only through formal training but through engagement with senior practitioners whose distinctive analytical voice they are absorbing. The institutional architecture of apprenticeship - partner mentorship, supervisory practices, the institutional rituals of senior-to-junior engagement - is the content through which the firm’s identity is reproduced across generations.

Internal vocabulary and cultural identity. Firms develop cultural identity through the internal vocabulary, the shared reference points, the distinctive ways of framing problems that constitute the firm’s collective discursive content. The cultural identity is not separable from the analytical work; it is part of what makes the firm’s analytical work distinctive.

The organisational scale of the integrated three-scale system is not homogeneous across the consulting sector. A distinction I treat as analytically important - with implications for how the proletarianisation risk the analytical chapters develop distributes across the consulting ecosystem - is the distinction between large advisory firms and SME and individual boutique practices.

In large advisory firms - the major management consulting houses and the advisory divisions of the large professional services networks - savoir-faire has historically been organised primarily through the institutional architectures the section has described. The firm’s competitive asset is substantially in its institutional knowledge architecture: its methodologies and frameworks, its case databases, its training curricula, the SECI cycle through which the distinctive way of seeing is reproduced across generations. Individual senior practitioners carry important personal judgment, but the firm’s identity as a knowledge-managing collective does not depend on any single individual - it depends on the institutional architectures that reproduce the firm’s character across generations of practitioners. For large firms, the Stieglerian mechanism identified in Chapter 3 operates primarily at this institutional level: it is the firm’s distinctive externalised knowledge that is exposed to the generic dis-individuation pressure Chapter 5 will develop, and it is the formal formation pipeline through which the firm reproduces its institutional identity that is structurally at risk when AI mediation substitutes for the formative engagements through which junior practitioners are made into senior ones.

The financial logic through which this formation pipeline has historically been sustained is also under direct pressure. The traditional model - in which large consulting firms hire substantial junior cohorts whose billing subsidises the cost of formation, with attrition eliminating most juniors as a small cohort progresses to partner - has been structurally reliant on the economic case for junior work. AI mediation attacks this financial logic directly: when the entry-level work is automated, the billing case for large junior cohorts weakens, and the institutional vehicle for the formation pipeline the Stieglerian argument describes is itself at risk. The dismantling of the entry-level formation pathway has been noted in practitioner-facing analysis: Tarki and Raczynski (2025) identify the same structural pressure in HBR, observing that firms are automating the junior work through which formation historically occurred without having an alternative mechanism in place [@tarki2025consulting].

In SME and individual boutique practices, the knowledge architecture is organised differently. The boutique’s value typically resides in the accumulated personal experience and judgment of one or a small number of senior practitioners: decades of knowing a specific regulatory environment, a specific type of project, a specific stakeholder field. Content externalisation is minimal and often actively undesirable - the boutique’s competitive asset is the individual’s personal judgment, not a transferable framework that a competitor could reproduce. The institutional architectures of the SECI cycle are present in attenuated form; what cannot be attenuated is the individual’s psychic individuation - the distinctive analytical voice, the relational intelligence, the accumulated instinct that makes the boutique’s senior practitioner who they are.

For boutique practices, the Stieglerian mechanism operates differently. The primary risk is not to a formal formation pipeline (boutiques rarely form practitioners at scale as large firms do) but to the individual’s psychic individuation under generic mediation: whether the boutique advisor, using generic AI tools whose default outputs are common across the market, can maintain the distinctiveness of their personal analytical voice, or whether the cumulative weight of generic mediation homogenises it. The dis-individuation pressure lands on the person rather than on the institutional architecture, and the resistant structures are correspondingly personal - the individual’s deliberate cultivation of the distinctive voice and relational depth that generic mediation tends to smooth away.

The distinction has analytical implications the subsequent chapters engage. At the sovereignty level (Chapter 5), generic dis-individuation operates on different substrates: firm-distinctive institutional knowledge in large firms, individual-distinctive personal judgment in boutiques, with different vulnerabilities and different forms of resistance in each case. At the stage-by-stage level (Chapter 7), the formation pipeline argument applies primarily to large firms whose scaling of practitioner development depends on formal formation architectures. Boutiques face the disruption at the individual level - the question is not whether the pipeline is intact but whether the particular senior practitioner’s judgment survives generic mediation intact.

These four institutional architectures together constitute the firm as a knowledge-managing collective. The framework treats this constitution as the organisational scale of the integrated three-scale system, with content that is at stake in the analytical chapters that follow. Annex F develops the SECI model for readers who require detailed engagement with its analytical apparatus.

4.4 The domain scale: what infrastructure advisory actually requires

The domain scale is the level of European infrastructure advisory as a public-interest tradition. The institutional features of this domain - its public-purpose engineering tradition, regulatory architecture, and EU governance frame - were introduced in Chapter 2 §2.3; what follows examines their epistemological content: what these features mean for the character of practitioner knowledge and what they require of the formation pathway. The framework treats the domain as producing the content the individual consultant develops contributory expertise in and that the firm reproduces through its knowledge-managing practices.

European infrastructure advisory operates through several components that the chapter develops in turn.

Variation across subdomains. The family of European infrastructure subdomains - transport, energy (with nuclear as particular case), water, defence, environmental, social, built-environment, urban - has variation in regulatory weight, time horizon, stakeholder shape, and decision character. Energy and water are the most heavily regulated, with extensive institutional architectures of price regulation, service standards, and public-interest obligations. Defence is institutionally distinctive, operating through procurement, security clearances, and strategic-autonomy concerns. Transport is moderately regulated with subdomain variation between rail and road. Environmental, social, and urban subdomains have variable regulatory architectures depending on the specific institutional context. The framework recognises this variation throughout the analytical chapters; the content is suited to the family, not any single subdomain.

Paris, 2023. An advisory firm is engaged on procurement governance for the EDF nuclear decommissioning programme - a sixty-year horizon, multiple generations of contractors, oversight by ASN layered over commercial governance by CEA and EDF simultaneously. The first client meeting lasts four hours. The senior consultant from the advisory firm does not speak for the first ninety minutes. She is learning the interlocking governance structure before she says anything useful. A colleague who has advised on airport privatisation and toll roads thinks this is excessive caution. She explains afterwards: in nuclear, a wrong framing embeds itself in a procurement framework that governs decisions thirty years from now. The consequence of getting the framing wrong is not a bad report. It is a governance structure that cannot be corrected by anyone who comes after us. The time horizon is not just a parameter in the model. It is a constraint on what kind of advice is responsible.

The unifying public-interest texture. Despite subdomain variation, the family is unified by the public-interest tradition that Chapter 2 introduced. The work - its orientation toward the publics whose lives are shaped by infrastructure decisions, its institutional architectures of regulatory engagement, its content of accountability across long time horizons - is shared across the subdomains, distinguishing the domain from generic management consulting. The framework treats this unifying public-interest texture as constitutive of the domain. Annex B develops the third box as the constituency through which the public-interest texture operates in advisory practice.

The dual character of technical depth and political judgment. European infrastructure advisory sits at the intersection of technical depth (the analytical apparatus required for engineering, financial, regulatory, and environmental analysis) and political judgment (the understanding of the political and institutional contexts within which infrastructure decisions are made). Neither component alone constitutes the domain; both are required, and the integration of the two components is what distinguishes infrastructure advisory from generic technical consulting on one side and generic political consulting on the other.

The role of contested knowledge. Infrastructure decisions are contested. The same engagement can be analysed in multiple ways - through cost-benefit frameworks, through equity frameworks, through climate-transition frameworks, through strategic-autonomy frameworks. Advisory work includes the institutional architectures through which contested knowledge is engaged: public consultations, regulatory hearings, multi-stakeholder processes, intergovernmental negotiations. The framework treats contested knowledge as constitutive of the domain, not as a problem to be solved but as the ground on which the work operates.

London, 2019. An advisory firm is commissioned by a statutory body to produce an economic assessment of the Heathrow third runway. The technical case is broadly supportable. The climate compliance question - whether the expansion is compatible with UK carbon budgets - is contested between the Department for Transport and the Committee on Climate Change, and no client brief has resolved it. In a public hearing before a parliamentary select committee, the senior partner is asked directly whether the firm’s analysis assumes climate compliance or treats it as a separate policy question. He says it is a separate policy question. He is technically correct; the firm was not commissioned to answer it. He is also, in saying so, taking a position in a genuine disagreement about what the advisory role is for: whether infrastructure advisers are responsible for the normative consequences of their analytical framings or only for the technical correctness of their models. The room knows it. He knows it. The answer he gives is defensible and incomplete and he has thought about it since.

These four components together constitute European infrastructure advisory as a domain. The framework treats this content as the domain scale of the integrated three-scale system, with content that is at stake in the analytical chapters that follow. The domain’s distinctive cultural and cognitive character - the shared vocabulary, the sectoral instincts, the contested-knowledge frameworks through which the domain recognises and engages its problems - is precisely what Alombert (2024) diagnoses as most exposed to generic dis-individuation: the symbolic misery that results when generic technical mediation progressively impoverishes the shared cognitive world through which a domain’s distinctive intellectual life is sustained [@alombert2024noetic].

4.5 How the three scales constitute one another

The framework’s contribution at this point is the claim that the three scales - individual, organisational, domain - are not independent layers but mutually constitutive. The integration is what makes the system substantive.

The mutual constitution operates through three relationships.

The individual is individuated by the firm and by the domain. The professional identity of the individual consultant - their distinctive analytical voice, their commitments, what they bring to engagements - is not produced in isolation. It is produced through the formative engagements the firm makes available, through the supervisory practices the firm operates, through the content the domain provides. The Foundation-stage consultant who is formed at one firm in one subdomain becomes a different practitioner from the Foundation-stage consultant who is formed at another firm in another subdomain, even where their formal training and personal capacities are equivalent. The individuation is integrated; it cannot be abstracted from the firm and the domain within which it operates.

The firm is individuated by the individuals it forms and by the domain it operates within. The identity of the firm - its distinctive way of seeing, its institutional content, its analytical voice - is not a static institutional architecture. It is reproduced across generations through the practitioners the firm forms, and it is shaped by the domain within which the firm operates. A firm that has worked extensively on European water utility regulation develops content distinct from a firm that has worked extensively on European energy market design, even where their methodological apparatus and institutional architectures are formally equivalent. The individuation of the firm is integrated with the domain.

The domain is individuated by the firms that work within it and by the wider European public-interest tradition. European infrastructure advisory as a domain is not a static institutional reality. It is reproduced across generations through the engagements the firms operating within it produce, through the institutional architectures the domain’s regulatory and political contexts maintain, and through the wider European public-interest tradition that the domain is part of. The domain at any moment is the content the firms working within it have been reproducing through their engagements.

The three relationships together constitute what I have called the integrated three-scale system. European infrastructure advisory operates through the integration; abstracting any one scale from the others loses content I treat as constitutive of legitimate practice in the domain.

The integration also has a consequence I treat as analytically important: a transformation that operates on any one scale propagates to the other two. A change in how the individual consultant is formed propagates to the firm whose identity is reproduced through forming individuals, and to the domain whose content is reproduced through firms reproducing individuals. A change in how the firm reproduces its distinctive way of seeing propagates to the individuals being formed within it and to the domain whose content depends on firms reproducing distinctive ways of seeing. A change in the domain propagates to the firms working within it and to the individuals being formed in those firms.

This mutual propagation is what makes the concerns of the analytical chapters important. The framework’s claim about contemporary AI mediation is not that any one scale is at risk in isolation. It is that the mediation operates across the three scales simultaneously, producing transformation at each scale and propagating consequences across the integrated system. Chapter 5 develops the political-economic argument for what the mediation is doing across scales. Chapter 7 traces the consequences through the three ChMC stages of professional progression. The content the chapter has described here is the content that is at stake in the analytical chapters that follow.

4.6 The integrated three-scale system

European infrastructure advisory materialises its expertise through three mutually constitutive scales. At the individual scale, formation proceeds through formal training, sustained engagement with consequential work, and senior judgment absorbed across the arc of a career. At the organisational scale, the SECI cycle turns tacit knowledge into institutional assets - methodologies, case databases, cultural vocabulary - while apprenticeship and senior practice continuously replenish what those assets cannot hold. At the domain scale, public-interest texture and contested knowledge keep the firm anchored in something larger than its own institutional identity: the European regulatory tradition and the third box whose conditions of life the work shapes.

The three scales constitute each other. The individual is individuated by the firm and by the domain. The firm is individuated by the individuals it forms and by the domain it inhabits. The domain is individuated by the firms working within it and by the wider European public-interest tradition. What any single scale looks like is partly a product of the other two.

Chapter 5 asks what contemporary AI mediation is doing to this integrated system: whether generic mediation operating across all three scales simultaneously threatens the sovereignty of the integrated identity, and whether the extraction dynamic - the SECI cycle running outward rather than inward - represents the mechanism through which the political economy of AI mediation operates on European infrastructure advisory specifically.
