What each body of research found
Edith Penrose’s 1959 work on the theory of the growth of the firm located the primary hidden cost in managerial capacity. Penrose argued that a firm’s genuine capacity to direct and coordinate growth is limited, and that growth exceeding this capacity produces a specific, measurable cost even when it is not recorded as one: declining marginal returns on each additional unit of growth, as existing managers are stretched across more activity than they can direct as effectively as they directed less of it. This cost is real, Penrose argued, but structurally difficult for conventional accounting to capture, because it shows up as a gradual erosion of quality and effectiveness rather than as a discrete, attributable expense.
Ronald Coase’s earlier 1937 analysis of why firms exist identified a related but distinct cost: what he called decreasing returns to the entrepreneurial or managerial function as an organisation internalises more activity. Coase’s argument was that the cost of organising one additional unit of activity inside a firm rises as the firm’s scale and complexity increase, eventually reaching a point where it exceeds the cost of the same activity being coordinated through the external market instead. This is a genuinely economic cost — in Coase’s framing, a real cost of coordination — that nonetheless rarely appears as its own line item, because it is distributed invisibly across the general cost of running an increasingly complex organisation rather than isolated as a specific expense attributable to growth pace itself.
Nelson Repenning and John Sterman’s research on the “capability trap,” developed through system dynamics modelling and case study analysis, identified a behavioural cost that compounds the structural ones above: organisations under growth pressure systematically underinvest in the capability that would let them absorb growth more sustainably, because the people who prevent future problems by building that capability receive little visible credit for problems that, as a result, never happen — while the people managing today’s visible crisis receive immediate recognition. This creates a self-reinforcing dynamic in which rapid growth actively discourages the investment that would make rapid growth more sustainable, producing a hidden cost that compounds over time rather than appearing as a single, identifiable event.
Larry Greiner’s research on organisational growth phases identifies a fourth, more structural cost: practices and systems that work well at one stage of growth become, without changing at all, a source of friction and constraint at the next stage. Greiner’s specific contribution is the observation that this transition tends to arrive as a recognisable crisis point rather than a gradual adjustment — meaning the hidden costs of outgrown practices often accumulate quietly and then surface abruptly, once the organisation crosses a threshold the older practices can no longer accommodate.
Where they agree
Across these four distinct bodies of research, spanning economics, organisational behaviour and strategic management, and developed across more than six decades, a consistent theme emerges: the costs of rapid growth are structural and often invisible to standard financial measurement, rather than absent simply because they are not deliberately hidden. Each researcher, working independently and for different purposes, arrives at some version of the same underlying claim — that an organisation’s capacity to absorb growth well is itself a finite resource, that exceeding it produces real costs, and that those costs tend to surface as degraded quality, coordination strain or an eventual, sometimes abrupt, slowdown rather than as an immediately attributable expense on any conventional statement.
There is also agreement, across this literature, that these costs are not simply a matter of insufficient resources in the general sense — more money, more people — because each account locates the constraint specifically in coordination and managerial capacity rather than in resource volume alone. Penrose was explicit that adding resources without adding proportional capacity to direct them does not resolve the underlying constraint; Coase’s framework similarly locates the cost in the difficulty of coordinating activity, not merely in the volume of activity being coordinated; Repenning and Sterman’s capability trap specifically describes organisations adding effort — working harder — without addressing the capability gap that effort alone cannot close.
Where they diverge
The bodies of research differ meaningfully in where they locate the primary lever for avoiding these hidden costs, and a leadership team drawing on this literature for practical guidance will find genuinely different emphases depending on which account it weights most heavily. Penrose’s framework points toward deliberately pacing growth to match managerial capacity — implying that the primary lever is growth rate itself, and that slowing down, when capacity has not kept pace, is a legitimate and sometimes necessary response. Coase’s economic framework is comparatively silent on pacing and points instead toward organisational design — how activity is structured and coordinated internally — as the more relevant lever, implying that a well-designed organisation can absorb faster growth than a poorly designed one at the identical rate.
Repenning and Sterman’s account diverges further still, locating the primary lever not in pace or design but in incentives and attention: their research suggests that even well-designed organisations growing at a sustainable pace can still fall into the capability trap if their reward systems consistently favour visible firefighting over invisible prevention, implying that the relevant intervention is cultural and incentive-based rather than structural or pace-related. Greiner’s framework, finally, points toward anticipation and timing — recognising which growth-phase transition an organisation is approaching and preparing deliberately for the shift in practice it will require, rather than either pacing growth down or redesigning structure in the abstract.
None of these four emphases directly contradicts the others; they are better understood as four different entry points into a shared underlying problem, each backed by a different kind of evidence — Penrose’s conceptual economic theory, Coase’s foundational transaction-cost analysis, Repenning and Sterman’s modelling and case studies, Greiner’s longitudinal observation of growth patterns across organisations. A leadership team is not required to choose one framework over the others; the research supports treating them as complementary lenses on the same set of hidden costs, each illuminating a different part of the picture.
What remains unresolved
What the literature does not resolve, even collectively, is how to measure these hidden costs reliably in real time, before they have already produced visible consequences. Each researcher’s evidence is, to varying degrees, retrospective — identifying the mechanism through case analysis or historical pattern rather than providing forward-looking metrics an organisation could monitor as an early warning system. This is a genuine gap rather than an oversight: the costs described are, almost by definition, the kind that resist conventional measurement, which is precisely what makes them hidden in the first place. A leadership team drawing on this research gains a clearer conceptual map of where to look, but the literature stops short of providing a reliable, quantified dashboard for tracking these costs as they accumulate, leaving that translation from concept to practical monitoring as work each organisation still has to do for itself.
The same pattern appears across many kinds of organisation; see Other Sectors for how it is read elsewhere.
Questions worth considering
- Which of the four costs described here — declining managerial effectiveness, rising internal coordination cost, underinvestment in prevention, or outgrown practices reaching a crisis point — currently seems most present in this organisation, based on available signals?
- Does this organisation’s current reward and recognition system favour visible, urgent firefighting over less visible, preventive investment — and if so, is that pattern deliberate or accidental?
- If growth pace were the primary lever being relied on to manage these hidden costs, is that reliance explicit and deliberate, or has growth pace simply never been considered as something the organisation could choose to moderate?
