Government innovation labs, policy prototyping, and the organisations bringing design methods into public administration are mostly nonprofits or academic centres, and most have names too long to say comfortably. Innovation for policy describes the field.
I4P also carries investment for people, fitting impact investing and social finance, an area with substantial capital behind it and a naming convention favouring mission statements over company names, and information for progress.
Three characters serves the practical requirement these organisations actually have: an identity fitting next to funders’ logos, surviving footnote-size print, and resisting inconsistent abbreviation by partners and press.
Fixed supply, established convention, and the extension the sector uses.
Enquiries welcome.
