Key Takeaways
- McKinsey estimates that roughly $130 trillion will flow into capital projects between 2022 and 2027, with around $24 trillion of heavy-industrial capital ready to deploy over five years. Capital availability is not the problem.
- The delivery system absorbing that capital is under strain. Two-thirds of owner organisations studied by IPA describe themselves as understaffed, and contractors report similar competency declines.
- Front-end definition quality has fallen. IPA's average FEL Index now sits well within the Poor range for the first time, execution speed on large projects has dropped around 20 percent over two decades, and average schedule slip has roughly doubled to around 18 percent.
- The cost of getting it wrong is documented. McKinsey's review of more than 300 billion-dollar megaprojects found average cost overruns of about 80 percent and schedule delays of about 50 percent.
- Governance and management are distinct disciplines. PMI's governance guidance defines governance as oversight and decision rights, separate from the work of delivery, and ties organisational maturity to delivering outcomes in a predictable, controllable and reliable way.
- The binding constraint on the deployment wave is capability, not capital. Independent assurance is the rational response to a delivery environment where reported status and observed reality can drift apart unseen.
For most of the last decade, the constraint on Energy, Minerals and Resources (EMR) growth was access to capital and the confidence to commit it. That constraint has eased. What has not eased is the capability to convert those commitments into delivered, operating assets at the standard the scale demands. While the wave is real, the capacity to govern it is the open question.
Why Do Megaprojects Fail Despite Massive Capital Investment?
The clearest signal comes from the people meant to execute the work. In a 2024 study of major industrial firms, Independent Project Analysis (IPA) found that two-thirds of owner organisations considered themselves understaffed, with the right competencies and depth of experience in short supply. IPA frames the cause plainly: there are not enough experienced people, and too thin a middle layer to train those being recruited. This is a structural shortfall rooted in demographics, accelerated by attrition, and now colliding with a surge in committed work. A pattern we see consistently at P-DAS.
The supply side offers no easy rescue. IPA notes that contractors have experienced similar competency declines, so the common reflex of handing risk to an engineering, procurement and construction firm does not restore the capability that owner teams have lost. Procurement itself has become a leading project risk: more than 75 percent of the projects IPA reviewed costing over US$50m in 2024 flagged procurement as a major risk, and equipment lead times that ran 18 months before the pandemic now run closer to 24. While capital can be raised relatively quickly, experienced owner teams, mature supply chains and disciplined front-end work take years to rebuild.
What Does the Evidence Say About the Delivery Gap?
The most consequential weakness sits at the front end, before execution begins. Front-End Loading, the discipline of defining a project properly before it is authorised, is the single most reliable predictor of outcomes in IPA's research across more than 25,000 projects. IPA's FEL Index measures how thoroughly scope, risk, cost and execution plans are understood by the time a board is asked to commit capital. The trend on that measure is going the wrong way.
IPA reports that its average FEL Index has worsened over five years and now sits in the Poor range for the first time, with only about 16 percent of recent projects entering authorisation with the level of definition needed to deliver predictably. In plain terms, more capital is being committed to projects that are not yet ready to receive it. And the consequences are visible in delivery.
As reported at IPA's 2025 Industry Benchmarking Consortium, execution speed on large projects has fallen by around 20 percent over two decades, and average schedule slip has roughly doubled to around 18 percent. The cost of weak definition compounds at scale. McKinsey's review of more than 300 billion-dollar megaprojects found average cost overruns of about 80 percent and schedule delays of about 50 percent. Bent Flyvbjerg's Oxford database of more than 16,000 projects is starker still: only 8.5 percent meet both their cost and schedule targets, and just 0.5 percent also deliver the benefits that justified them.
These are not isolated failures. They describe the base rate that any new capital programme inherits unless it is governed against the pattern.
How Does Governance Differ From Management?
Part of the gap is conceptual. Governance and management are frequently treated as the same activity, and they are not.
To understand the difference between project governance and project management, we can look at PMI’s guidance. Project governance is the framework of oversight, decision rights, and authority that determines whether work should proceed, while management is the organising and doing of the work itself. A stage gate, in this framing, is not an administrative checkpoint, it is the point at which an organisation decides whether continued investment is justified by the project's current readiness, with the authority to stop, reshape or continue.
The same guidance ties organisational maturity to the ability to deliver strategic outcomes in a predictable, controllable and reliable manner. That is a precise description of what the deployment wave is testing. An organisation can have ample capital, a credible strategy and a full project list, and still lack the governance maturity to convert commitments into operating assets without value leaking away.
The risk intensifies under the pressure of a busy portfolio. When experienced people are scarce and the schedule is unforgiving, oversight is often the first thing to thin out. A gate review becomes a presentation to be survived rather than a decision to be earned, and a programme management office that should be challenging readiness settles into collecting status reports. The gate still happens, but it no longer does its job, and the discipline that protects capital quietly disappears at the precise moment the capital at stake is largest.
We have examined this distinction in the context of what boards should be asking about their capital projects.
Where the Capability Gap Shows Up
The failure mode is rarely a shortage of money. It is the erosion of definition and oversight under pressure. Three recent capital project case studies highlight how these governance failures manifest in the Energy, Minerals, and Resources (EMR) sectors.
At Golden Pass LNG in Texas, a joint venture between owners with deep balance sheets, the lead construction contractor filed for bankruptcy in 2024 amid a cost blowout, idling thousands of workers and triggering disputes over scope, site conditions and schedule acceleration.
Teck's Quebrada Blanca Phase 2 copper project in Chile was sanctioned at around US$5.2bn and ultimately reported at close to US$8.7bn, roughly US$3.5bn over, with ramp-up further hampered by tailings and production problems that prompted a comprehensive operations review.
The Trans Mountain pipeline expansion in Canada is perhaps the clearest illustration. Owned by a federal entity with effectively unlimited access to capital, its cost rose from an original estimate of around C$5.4bn to roughly C$34bn. The company itself attributed the majority of its most recent overrun to engineering and plan maturity, which is to say to front-end definition gaps. An owner with the deepest possible pockets still overran sixfold, because the shortfall was in capability, not funding.
The common thread is that capability deficits stay invisible until they surface as cost and schedule failure, often after the window to correct them has effectively closed. This is the gap that independent oversight is designed to catch, a theme we explore in why internal assurance alone isn't enough and in governing distributed capital programme teams.
What Does the Rational Response Look Like?
If capability is the constraint, the response is to govern for it deliberately rather than assume it. In practice that means treating front-end definition as a gate to be passed, not a box to be ticked - staffing the owner function with enough experienced people to maintain genuine oversight, and building independent verification into the programme from the outset - so that reported status can be tested against observed reality before variances become irreversible.
In practice, the most effective tool is a third-party independent project assurance review or a stage-gate readiness review at the end of FEL 3, before final investment decision: a structured assessment, conducted by experienced practitioners outside the project team, that tests whether scope, schedule, cost estimate, contracting strategy and owner-team staffing are genuinely ready for the commitment being asked of the board. The output is not another status report. It is a defensible answer to the question of whether the project should proceed as proposed, be reshaped, or be deferred. That is the discipline the FEL Index is measuring, applied by an oversight function that has no commercial reason to confirm a decision that has already been made.
None of this slows capital deployment. It protects the return on it. IPA's own data shows that projects reaching good or best practical front-end definition are materially more cost-effective than those that do not, and that adequately staffed owner teams deliver at lower cost and with less slippage. The organisations that extract real value from this wave will not be those that move the most capital fastest, it will be those with the governance discipline to deliver what they have committed to, with the rigour the scale demands.
The same logic underpins disciplined risk management in mega-projects, and it is the difference between programmes that protect capital and those that, as we have written, explain in hindsight why megaprojects keep failing.
PDAS provides independent governance and assurance for Energy, Minerals and Resources capital programmes, verifying that reported status reflects delivery reality before value is lost.
