Ten domains, five stages, one heat map. This guide shows funders and DFIs how to turn a country or regional maturity assessment into an investment sequencing decision.
The INA Digital Infrastructure Maturity Model™ (F3) scores a country, region or organization across ten domains of digital infrastructure, from Initial to Leading. Unlike the Investment Readiness Index, which scores a single project, F3 assesses an ecosystem — it's the tool for deciding where in a country's portfolio to put the next dollar, not whether a specific project is bankable.
This guide is written for a funder or DFI program officer building a country strategy: how to read the ten-domain heat map, what the five stages actually imply for sequencing, and the benchmarking mistakes that most commonly distort investment decisions.
“A country that is Leading in connectivity and Initial in cybersecurity does not need another connectivity loan. It needs a cybersecurity program.”INA Digital Infrastructure Maturity Model™ — User Notes, 2026
Each of the ten domains is scored independently against the same five-stage scale, from Initial to Leading. A country's overall maturity is a profile across all ten — almost never a single flat stage.
Domain-based, not project-based — F3 assesses the ecosystem a project would sit inside, which is what makes it useful for portfolio-level sequencing decisions rather than single-project approval.
The Maturity Heat Map plots all ten domains side by side on the same five-stage scale. The pattern across domains matters more than any single domain's score.
An uneven profile — strong in one or two domains, weak in the rest — is the most common pattern and usually the most actionable one: it points directly at the next domain worth funding.
Cybersecurity or Regulatory Environment weaknesses often cap what connectivity or datacenter investment can safely achieve — fix the blocking domain first.
Marginal returns fall fast once a domain is Advanced — redirect that budget to a Developing or Emerging domain instead.
F3 is designed as a living dashboard, not a one-time snapshot — stale data understates real progress and misdirects the next round of funding.
| Pitfall | Why It Distorts Sequencing |
|---|---|
| Comparing countries of very different scale as if maturity were size-normalized | A small country can reach Advanced connectivity faster than a large federal one with the same investment — scale changes the baseline |
| Averaging the ten domains into one number | Averaging erases exactly the uneven pattern that makes the heat map useful for sequencing |
| Treating a high score as permanent | Cybersecurity Posture in particular can regress quickly without sustained investment |
The Maturity Model™ is a sequencing tool, not a scoreboard. Its value is in the shape of the ten-domain profile, not the headline stage — used well, it tells a funder exactly where the next dollar in a country portfolio does the most good.
