ISO 44001 Collaborative business relationship management systems – Requirements and framework is a proposed international standard under development with the International Organisation for Standardisation. It is based on British Standards BS 11000, initially developed from 2006 as PAS 11000 (2006).

BS 11000 was formally launched at the House of Lords in London on 7 December 2010.
The Institute for Collaborative Working, which promotes BS 11000 and ISO 11000, argues that there is a case for this standard because "as [businesses] see greater reliance on external parties to deliver solutions and an increase on contracting for outcomes, the emphasis on collaborative working will grow".
