Half Double is an open source Project and Portfolio Methodology developed by the Danish Industry Foundation and Aarhus University together with Implement Consulting Group.
Half Double is free for all to use in projects and portfolios but If you want to be trainer, educator or consulting partner in the concept and be able to nominate for certification as Foundation, Practitioner or Master you will need to be registered partner with Half Double Institute. This way we strike the balance between being open for all to use and ensuring high quality standards of the certification program.
