Cost-Benefit Analysis for National Scale Digital System Implementation

Client: Large IT company

The challenge
A Croatian IT company engaged us to develop a rigorous, independent cost–benefit analysis for an innovative IT system intended for national‑level implementation in the public sector. The system targets a complex operational and governance problem spanning multiple institutions, high transaction volumes and significant fiscal and social implications.
To make a convincing case for investment, they needed more than a financial model: they needed a credible analytical framework that reflects the full regulatory context, draws on international experience and anticipates the questions senior public‑sector decision‑makers will ask — in a format suitable for the highest levels of government.

What we did
We produced a comprehensive 100‑page analysis built around three components: (1) detailed mapping of the existing regulatory and operational landscape across relevant institutions and funding streams; (2) international benchmarking that extracted key operational lessons from comparable systems abroad; and (3) a full cost–benefit framework covering implementation, operational and transition costs against fiscal, administrative and systemic benefits. The document also included a minimum functional specification defining core system capabilities, user roles and process flows.

Outcome
A 100‑page cost–benefit analysis was delivered and prepared for senior public‑sector review. It serves decision‑makers by clarifying the scope and systemic implications of the investment, and IT teams by providing a structured minimum functional specification that sets out non‑negotiable capabilities and constraints — so all stakeholders understand exactly what they are committing to.
