Strategic misrepresentation is the deliberate distortion of project costs, benefits, schedules, or risks to improve the chance of approval or funding.
Strategic misrepresentation is the deliberate understatement of costs, delivery time, or risks, or the deliberate overstatement of benefits, demand, or funding capacity, to improve a project’s chance of approval. It can affect public infrastructure, corporate capital budgets, acquisitions, procurement, and policy programs. Intent distinguishes it from optimism bias, estimation error, and unforeseen scope change.
| Explanation | Intentional? | Typical feature | Appropriate response |
|---|---|---|---|
| Strategic misrepresentation | Yes | Known adverse assumptions are omitted, suppressed, or altered to secure approval | Investigate incentives, evidence trail, representations, and accountability |
| Optimism bias | No | Appraisers systematically expect better cost, schedule, or benefit outcomes than experience supports | Apply evidence-based uplifts, outside-view forecasts, and calibration |
| Estimation error | No | Data, model, or arithmetic produces an inaccurate estimate | Improve data, model validation, and technical review |
| Scope change | Not necessarily | Approved outputs or requirements change after the baseline | Rebaseline transparently and separate approved changes from original error |
| Unforeseeable event | No | A genuinely unanticipated shock changes delivery or benefits | Update scenarios, contingency, insurance, or risk allocation |
The distinction matters for governance, but it can be difficult to establish after the fact. People may have mixed motives, assumptions may be ambiguous, and project scope can evolve. Reviewers should avoid inferring intent from one unfavorable outcome.
Sponsors competing for limited public funds may understate construction cost, land risk, completion time, operating subsidy, or demand uncertainty. Once work begins, sunk costs and political commitment can make cancellation more difficult.
Managers may present aggressive sales forecasts, low implementation costs, or optimistic terminal values to obtain internal capital. Performance incentives, divisional competition, and promotion goals can intensify the conflict.
An acquisition case can overstate synergies, speed of integration, customer retention, or cost savings while understating transaction costs, dis-synergies, and execution risk.
Borrowers or sponsors may present optimistic utilization, collateral, construction, or cash-flow assumptions. Independent engineering, market, legal, and model reviews are intended to challenge those inputs, not guarantee repayment.
Assume a project is expected to produce level net benefits for 10 years and is evaluated at an 8% discount rate.
The sponsor presents:
The 10-year annuity factor at 8% is approximately 6.710. Presented net present value is therefore:
An independent outside-view review of comparable completed projects estimates:
The presented assumptions support approval, while the independent case rejects the project on the same discount-rate and timing basis. The $85.2 million NPV gap comes from the cost and benefit assumptions, not a change in valuation method.
This example demonstrates decision sensitivity. It does not prove strategic misrepresentation unless evidence shows the sponsor knew the presented assumptions were misleading or deliberately suppressed contrary evidence.
Continuing a project after new information is not automatically irrational. The relevant decision at each stage is forward-looking, but the original forecast should still be retained for governance and learning.
Archive the original model, assumptions, source data, sponsor adjustments, risk register, approvals, and later revisions. Require each change to identify whether it reflects new information, scope, correction, or management judgment.
Compare the project with a broad, relevant class of completed projects at a similar maturity stage. Homes England’s reference-class forecasting guidance explains how historical distributions can inform cost and schedule risk and identifies both optimism bias and strategic misrepresentation as sources of underestimation.
Give independent reviewers access to source data and authority to challenge scope, demand, cost, schedule, financing, and benefit assumptions. Independence is weakened if the reviewer depends on project approval or sponsor-controlled information.
Use scenarios, sensitivity analysis, and probabilistic ranges rather than one approval number. Include low-demand, delay, refinancing, cost-inflation, and implementation-failure cases where relevant.
Release capital in stages and require reapproval when cost, schedule, scope, or benefits cross defined thresholds. Do not let prior expenditure substitute for an updated business case.
Track final cost, completion time, utilization, revenue, operating cost, and realized benefits against the approval baseline. Repeated directional errors can reveal calibration problems or incentive failures.
The UK government’s Green Book 2026 requires explicit treatment of optimism bias using historical forecast errors or relevant comparable projects. That method corrects systematic bias even when intent cannot be established.
Projects face genuine uncertainty. Intent requires evidence such as ignored data, contradictory internal forecasts, unexplained assumption changes, or incentives combined with a documented decision trail.
A percentage reserve can mask an implausible scope, demand forecast, or schedule. Base assumptions, uncertainty, contingency, and management reserve should remain distinguishable.
Cherry-picking unusually successful comparators can reproduce the original bias. Selection criteria and exclusions should be documented before results are known.
If compensation or status depends on securing authorization but not on delivery, governance can encourage aggressive forecasts even when models appear sophisticated.
Cost overruns are visible, but lower usage, delayed adoption, weak synergies, or unmeasured social benefits can be equally important to the investment case.
