Building a Multi-Dimensional Scoring System for National Investment Capability — Lessons from GNICAP

Most of us in the dev/data community have built scoring systems at some point — user reputation scores, credit risk models, recommendation engines. But what happens when the thing you're scoring is an entire country's investment capability? That's essentially what the Global National Investment Capability Assessment Program (GNICAP) has attempted to do. And whether you're interested in global finance or not, the architecture of their evaluation framework has some interesting design patterns worth examining. The Problem Statement The Global National Investment Capability Assessment Program (GNICAP) needed to answer a deceptively complex question: How do you objectively rank the investment capability of representatives from different nations, in a way that institutional capital would actually trust?
