COMMON CHALLENGES

Barriers to Moving Forward

Getting clear impact results can be harder than it should be. These are the most common hurdles.

Time Inefficiencies

Traditional economic impact assessments can take time - while project decisions and deadlines keep moving.

Cost & Scope

Full economic studies can be costly when you need credible figures or want to test a few development scenarios.

Outdated Data

In-house models may rely on outdated assumptions and benchmarks that no longer reflect current development conditions.

Credibility Gaps

Internally prepared impact figures may face scrutiny and can be difficult to substantiate without a transparent methodology.

Complex Modelling

Economic impact modelling requires appropriate inputs, sound methodology and informed interpretation for credible results.

Missing Link

Economic and planning impacts are often considered separately, even though development decisions are shaped by both.
