5I

INTRODUCTION
English translation pending.
CORE DEFINITION
The 5I framework distinguishes five stages in the life of an innovation: idea, the original thought; invention, a working technical solution; innovation, the point at which it succeeds commercially; imitation, the spread of the approach through the market; and investment, the allocation of resources that supports the later stages. Different scholars define the terms slightly differently, but the practical purpose is to separate technical novelty from commercial success.
SCAFFOLDING EFFECT
Reduce cognitive load
- Label the stage: identify whether your project is an idea, an invention or a commercial innovation. - Demand the market: treat commercial adoption as the test rather than technical novelty. - Watch diffusion: study how imitators spread the approach and what that does to your position.
Anchor fast decisions
A working technical solution has no economic value until someone pays for it, and the skills that produce the invention are not the skills that sell it. Separating the stages forces the question of which one the team is actually in and what that stage requires. Confusing invention with innovation is the most common source of wasted research investment.
