Institutional position
British in origin. International in application.
AIMM was developed through public-sector use, independent research and practical deployment. It is maintained as an open standard rather than a proprietary consulting method.
Its language is designed to travel across sectors, jurisdictions, technologies and delivery models without privileging a particular supplier.
