A public initiative can be economically attractive and still fail the investment test if it lacks legitimacy, operational capacity or sufficient public value.
Public-sector investment decisions are difficult because the organisation is rarely optimising one clean objective.
A government agency may need to improve service outcomes, satisfy legal obligations, protect vulnerable groups, manage budget limits, maintain public confidence and preserve the capacity to deliver other services at the same time.
The supplied cost-benefit study notes recognise this difficulty. They distinguish public decisions from narrower private-sector analysis, emphasise externalities and intangible benefits, and introduce a public-value framework based on three connected elements: public value, legitimacy and support, and operational capacity.
That triangle offers a useful executive test.
A proposal is not strong merely because it promises benefit. Leaders must also ask whether the benefit is publicly legitimate and whether the institution has the capability to produce it.
The Strategic Context
Public value expands the definition of investment success beyond financial return.
A program may create significant social benefit but be impossible to administer at scale. Another may be operationally easy but lack stakeholder legitimacy. A third may have strong political support but weak evidence that it will improve outcomes.
These are different failure modes.
The public-value perspective is useful because it forces decision-makers to consider them together.
It is especially relevant to infrastructure, healthcare, education, defence, regulation and public-sector transformation, where the people who fund, use, experience and govern the service are not always the same group.
What Leaders Commonly Misread
The first misreading is that public value means whatever is popular.
Legitimacy and support matter, but public value cannot be reduced to immediate approval. Some investments may be necessary despite controversy. Others may be popular but operationally unsustainable.
The second misreading is that a positive CBA settles the decision.
Cost-benefit analysis can provide important evidence, but the supplied notes explicitly observe that public acceptance, political factors, operational capacity and trust can affect feasibility and value perception.
The third misreading is that operational capability is a delivery problem to solve after approval.
If the institution cannot realistically implement, maintain or govern the proposed change, operational weakness is an investment issue.
Reframing the Issue
The public-value triangle can be translated into three executive questions.
Public value: Is the outcome worth creating?
This concerns the substantive benefit to citizens, users, communities or the public interest.
The benefit may be economic, social, environmental, safety-related or service-related. Some elements may be monetisable through CBA; others may need qualitative evidence.
Legitimacy and support: Is the organisation authorised and supported to act?
Legitimacy can come from law, policy, elected authority, stakeholder consent, professional norms, community trust or institutional mandate.
Support affects whether the initiative can survive the political and organisational friction of implementation.
Operational capacity: Can the institution actually produce the outcome?
Capacity includes funding, people, technology, procurement, governance, partners, data, infrastructure and management capability.
A proposal can be valuable in theory and still be irresponsible to approve if the delivery system is not capable of producing the promised outcome.
The key insight is that none of the three dimensions is sufficient alone.
Public Value and Externalities
The cost-benefit material gives the public-value discussion an economic foundation.
Public projects often create effects outside the budget of the sponsoring agency. A transport decision can affect households, businesses, environmental amenity and other modes of transport. Education can influence future income, productivity and social outcomes. Environmental decisions can change health, land value or future remediation costs.
These external effects are part of the real system even when they do not appear in departmental accounts.
Public value therefore requires leaders to think beyond organisational performance measures and consider who gains, who loses and who bears risk over time.
The Legitimacy Problem
Legitimacy becomes especially important when the distribution of costs and benefits is uneven.
A project may create net benefit overall while imposing concentrated losses on a smaller group. A purely aggregate analysis can hide that political and ethical reality.
This does not mean every negatively affected stakeholder can veto action. It means leaders need to understand distribution, consultation, compensation, transparency and the basis on which the decision is authorised.
The practical question is not whether opposition exists. It is whether the institution has enough legitimacy to proceed responsibly and sustain implementation.
Operational Capacity Is Part of Strategy
Public strategies often fail when the promised outcome exceeds the capacity of the delivery system.
A policy may require workforce that cannot be recruited. A digital service may depend on data that agencies cannot integrate. An infrastructure commitment may require maintenance funding that is never secured. A new process may add compliance burden to an already constrained frontline.
These are predictable strategic risks when capacity is assessed honestly.
Operational capacity should therefore be tested before commitment, not discovered through implementation failure.

Public Value Is Often Created Through Trade-Offs
The public-value frame is useful partly because it prevents leaders from pretending that every objective can be maximised simultaneously.
A transport project may improve access but affect amenity. A health initiative may expand coverage but create workforce pressure. A regulatory change may improve safety while increasing compliance cost. In plural stakeholder systems, these tensions are normal.
The executive responsibility is therefore to make the trade-off explicit and explain why it is acceptable within the institution's mandate.
This is where legitimacy and support become more than communication. They help determine whether the trade-off is understood, authorised and sustainable enough for the institution to proceed.
Capacity Should Be Tested at the Operating Level
Operational capacity is easily overstated when assessed only at organisational level. An agency may have substantial total funding and headcount while the specific teams needed for implementation are already constrained.
A more realistic capacity test examines the actual bottlenecks: specialist staff, procurement lead time, data quality, frontline workload, technology interfaces, partner readiness and leadership attention.
This makes capacity a system property rather than a budget line.
If the weakest dependency cannot support the initiative, nominal organisational scale does not make the project feasible. Leaders may need to stage the work, reduce scope, build capability first or sequence the investment behind another priority.
Decision Framework
A public-value investment review can use a balanced test.
| Dimension | Core question | Typical evidence |
|---|---|---|
| Value | What meaningful outcome will improve, and for whom? | Outcomes, CBA, service evidence, strategic need |
| Legitimacy | On what authority and with what stakeholder support can we act? | Mandate, consultation, policy, legal basis, trust indicators |
| Capacity | What capabilities are required to deliver and sustain the outcome? | Funding, workforce, systems, partners, governance, operating model |
The proposal should then be stress-tested for imbalance.
High value with low capacity suggests redesign or staged investment.
High value with weak legitimacy suggests stronger engagement, clearer authority or reconsideration of the delivery approach.
High legitimacy with weak value suggests political momentum may be outrunning evidence.
High capacity with weak value suggests the organisation may be doing what it knows how to do rather than what matters most.
From Strategy to Execution
Immediate action: add value, legitimacy and capacity explicitly to major public investment submissions.
Medium-term capability: connect CBA, stakeholder analysis and organisational-capability assessment rather than allowing them to sit in separate workstreams.
Long-term positioning: track whether delivered programs continue to create public value after project completion. Changes in trust, demand, policy, technology or operating conditions can alter the balance over time.
This turns public value into an ongoing governance lens rather than a planning slogan.
Signals to Monitor
Leaders should reconsider the investment when:
- public outcomes are vaguely defined while project outputs are precise;
- consultation is treated as communication rather than evidence;
- the policy mandate is clear but delivery capacity is weak;
- benefit claims depend on behaviour that users have little incentive to adopt;
- operating costs or workforce implications sit outside the investment case;
- opposition is dismissed without understanding who bears the losses;
- political commitment prevents honest reassessment of feasibility.
These signals suggest the initiative may be strong in one corner of the triangle and weak in another.
Questions for the Leadership Team
- What public value are we trying to create, in terms that can be observed after implementation?
- Who gains and who bears the cost or disruption?
- What gives the organisation legitimacy to act?
- What level of stakeholder support is necessary for implementation to work?
- Do we possess the operational capacity to deliver and sustain the promised outcome?
- Which constraint is currently weakest: value, legitimacy or capacity?
- If one corner deteriorates, what would cause us to redesign or stop the initiative?
Closing Perspective
Public investment cannot be reduced to financial return, technical feasibility or political approval.
The stronger test is whether the initiative creates meaningful public value, is legitimate enough to sustain action and sits within a delivery system capable of producing the outcome.
When leaders evaluate all three together, they are less likely to approve initiatives that look attractive in analysis but cannot survive contact with institutions, stakeholders and operational reality.
