Why boards should govern assumptions with the same discipline as money
Capital allocation is usually described as the point at which strategy becomes real. A company may hold strong views about markets, technology, and growth, but those views acquire consequence only when money, talent, and management attention are committed behind them.
This is true, but incomplete.
Capital does not allocate itself. It follows a prior set of judgments about how value will be created, which capabilities will remain scarce, where ownership matters and how long an economic model can endure. These judgments determine the destination of capital before the investment committee discusses returns.
They constitute what I call Assumption Capital: the body of beliefs through which an institution interprets opportunity and allocates its resources.
Every enterprise possesses it. Few govern it explicitly.
Modern institutions have developed considerable sophistication in the management of financial capital. Assets are valued, returns measured, scenarios modelled and investment theses tested against changes in price, demand and financing conditions. Yet the assumptions beneath those models are often treated differently. They are embedded in strategy, inherited through organisational design and reinforced by historical success. Over time, they cease to appear as judgments and begin to function as facts.
The problem is not that these assumptions were poorly conceived. In many cases, they were responsible for creating the very advantage the institution is seeking to protect. Scale may have delivered purchasing power. Ownership may have secured quality and control. Physical reach may have defined convenience. Technical capability may have created genuine scarcity. A centralised model may have preserved standards during a period of rapid expansion.
But assumptions have economic lives. Their relevance can change even while the assets built upon them continue to perform.
This creates a blind spot in conventional strategy. Boards can observe when an asset underperforms, but they are less equipped to identify when the logic supporting that asset has begun to evolve. Revenue may still grow. Margins may remain defensible. Market position may appear secure. The institution can therefore continue reporting success while allocating an increasing share of its resources through a view of the world that is becoming less complete.
The strategic challenge is not simply to identify competitive advantage. It is to understand the assumptions that produce it, the conditions under which they remain valid and the point at which they require renewal.
Artificial intelligence offers a useful illustration because the economics are moving with unusual speed. Stanford’s 2025 AI Index found that the cost of querying a model performing at roughly GPT-3.5 level fell from $20 per million tokens in November 2022 to $0.07 by October 2024, a decline of more than 280 times in approximately 18 months. Depending on the task, large-language-model inference costs were falling at annual rates ranging from ninefold to 900-fold. (Stanford HAI)
The important conclusion is not merely that AI became cheaper. It is that a capability perceived as scarce at the start of an investment cycle could become broadly accessible before the cycle was complete.
That changes the investment question. A board considering a multiyear capability build must ask not only whether the technology will work, but whether the scarcity value supporting the investment will still exist when deployment is complete. If access is becoming commoditised, value may migrate towards proprietary data, customer relationships, workflow integration, governance or the ability to redesign decisions around the technology.
An institution can therefore make the correct technology investment and still rely on the wrong assumption about where advantage will reside.
This distinction matters because many businesses treat technology as an addition to the operating model rather than a reason to reconsider it. They automate existing activities, accelerate reporting and improve analytical capacity, but preserve the same decision rights, hand-offs and organisational boundaries. The technology performs; the economics change less than expected.
The historical experience of electrification is instructive. Productivity did not rise simply because factories replaced steam engines with electric motors. The larger gains came when factories were reorganised around distributed power, allowing production layouts and workflows to change. The value emerged not from adopting the technology alone, but from revising the assumptions embedded in the system surrounding it.
The same principle applies beyond technology. A distribution network can remain a valuable asset while the definition of convenience shifts. A strong brand can retain recognition while influence moves towards communities and platforms. Scale can continue lowering unit costs while adding coordination costs that are harder to see. Ownership can provide control in one part of a value chain while limiting access to capability in another.
None of these advantages necessarily disappears. Their economic role changes.
A rigorous approach to strategy should therefore treat assumptions as investments that must continue earning confidence. This is not an argument for constant revision or institutional restlessness. Strategic conviction remains essential. The purpose is to distinguish conviction from inertia by making explicit what must remain true for an investment thesis to continue creating value.
In practice, the earliest signs that assumptions require review are rarely dramatic. They appear as compensating complexity. Additional governance is introduced because accountability no longer resolves trade-offs. Senior positions are added around recurring problems. Investment decisions take longer even as the quality of information improves. New priorities receive incremental funding, but historical activities retain their full resource base. Strong businesses support others whose role in the portfolio has become difficult to articulate.
These conditions are often treated as organisational matters. They are better understood as capital-allocation signals.
When an institution cannot translate strategic change into resource movement, it develops a gap between what it says matters and what it continues to fund. This gap may remain hidden because each individual initiative appears reasonable. The portfolio becomes less coherent not through one poor decision, but through the accumulation of decisions whose underlying assumptions are no longer connected.
The organisation becomes busier without becoming more strategically mobile.
This is where many transformation programmes reach their limit. They simplify processes, reduce cost and redesign structures, but stop short of revisiting the investment logic of the enterprise. Efficiency improves, yet the destination of capital remains broadly unchanged. The institution becomes a better operator of its current model without establishing whether that model should continue receiving the same share of resources.
Transformation creates value only when strategic intent is followed by allocation. Budgets must move. Leadership attention must move. Talent and authority must move. Measures of success must move. Activities that no longer support the chosen direction must be reduced or concluded. Otherwise, the organisation funds both the future and the institutional architecture of the past.
Microsoft’s cloud transition is relevant because it was not simply a successful product expansion. The company shifted its commercial model, technical architecture, capital investment and organisational centre of gravity towards cloud services. In its 2025 fiscal year, Azure surpassed $75bn in revenue and grew 34 per cent. (Microsoft)
The significance lies in the scope of the institutional movement. Microsoft did not merely attach cloud services to a software business. It changed what the enterprise was designed to scale and monetise. The existing customer base, engineering capability and commercial reach remained valuable, but their role was reinterpreted around a different economic model.
That is the constructive purpose of governing Assumption Capital. It is not to reject what made the institution successful, but to determine how those strengths can be repositioned as value moves.
This is particularly important in portfolio organisations. Diversified groups and sovereign investors are often judged by the quality of their assets and their access to capital. A further source of advantage lies in their ability to recognise when a capability developed in one asset may create greater value elsewhere.
A procurement capability can become a sourcing platform. Distribution infrastructure can support third-party services. Operational data can improve decision-making across a portfolio. Supplier access can form the basis of a broader ecosystem. A capability originally built as a cost centre may acquire the economics of a growth platform.
The question is not merely whether a capability is strong. It is whether its highest-value application remains within the business for which it was created.
Ørsted’s transition illustrates the scale of institutional repositioning that can follow from such a reassessment. In 2008, 85 per cent of its heat and power production was based on fossil fuels, with only 15 per cent based on renewables. The company initially expected to reverse this ratio over 40 years, but ultimately did so in approximately ten, withdrawing from new coal projects and developing a renewable-energy model around offshore wind. (Ørsted)
The important feature of this case is not foresight alone. The company redirected capital while the previous model still possessed assets, expertise and institutional legitimacy. It did not wait for the historical business to lose all value before establishing the economic logic of the next one.
For long-duration investors, this distinction is fundamental. Patient capital creates the freedom to invest through cycles, support complex transitions and avoid decisions driven by short-term volatility. But patience is valuable only when accompanied by active scrutiny of the thesis.
A temporary decline in performance does not necessarily invalidate an investment. Equally, current profitability does not necessarily confirm its long-term relevance. Price volatility and strategic change are different phenomena. One affects the market value of an asset. The other affects the mechanism through which it will create value.
Long-term ownership should therefore allow earlier strategic renewal, not delayed recognition.
This requires boards to expand the way they review portfolios. Traditional capital allocation asks where to invest, where to improve returns and where to reduce exposure. Governing Assumption Capital introduces a prior set of questions.
What must remain true for this investment to create value?
Which assumptions are common across multiple assets?
Where is the portfolio diversified by sector but concentrated in the same beliefs about customers, technology, regulation or geopolitics?
What evidence would prompt a reassessment?
How readily could capital, leadership and decision rights move if the thesis changed?
These are not theoretical questions. They influence the quality of the portfolio before financial outcomes make the answer visible.
They also improve the discipline of ownership. Businesses are frequently described as strategic, core or growth platforms without specifying what those labels mean for resource allocation. A strategic asset should have a clear reason for receiving disproportionate capital and leadership attention. A cash-generating business should have an explicit role in funding future capability. A turnaround should be supported by a defined value-creation thesis and measurable milestones. An asset held for broader national or institutional objectives should be governed through a mandate that makes those objectives transparent.
Ambiguity may support short-term alignment, but it weakens the quality of capital allocation.
The most revealing portfolio question may therefore be neither “Is this business performing?” nor “Can it be improved?” It is “Why are we the right owner?”
The answer may lie in capital, governance, capability, market access, strategic influence or the ability to create value across a wider ecosystem. If ownership provides no distinctive advantage, the institution should be willing to reconsider the form through which it participates. Partnership, consolidation, partial ownership, separation and market exit are not admissions of strategic failure. They are instruments of capital discipline.
Assumption Capital also changes how talent should be viewed. Leadership is often treated as a support requirement after the investment thesis has been approved. In reality, leadership capacity is part of the investment itself. A market-entry strategy without leaders capable of building the local model is undercapitalised. A turnaround assigned to developing talent carries a different risk profile from one led by an experienced operator. A new platform without clear authority may receive financial capital but lack the institutional capital required to scale.
The same applies to organisational design. Reporting lines are not merely structural choices. They determine where information meets authority, how quickly trade-offs are resolved and whether accountability follows economic value. When strategy changes but decision rights remain fixed, the institution has altered its ambition without altering its ability to act.
This is why Assumption Capital belongs in the boardroom rather than inside the transformation function. It sits upstream of organisation, technology and execution. It shapes what the institution considers attractive, which risks it is willing to accept and what evidence it is prepared to recognise.
It also offers a more constructive interpretation of competitive advantage. Advantage should not be viewed as a fixed asset that must be protected in its original form. It is the economic return generated by a coherent set of choices, capabilities and assumptions. Its durability depends not only on the strength of the position, but on the institution’s ability to update that coherence as conditions evolve.
The most capable institutions will not be those that revise their strategies most frequently. Constant change can destroy focus and institutional memory. They will be those that know which assumptions are foundational, which are provisional and which have already served their purpose.
That is ultimately a question of judgment.
Financial governance asks whether capital has been allocated efficiently. Strategic governance must also ask whether it has been allocated through beliefs that continue to merit confidence.
Every major investment is made twice: first as an assumption about the future, then as a commitment of resources.
Boards have developed considerable discipline around the second decision.
The next evolution of institutional governance is to apply the same discipline to the first.
