Asset Management Standards



For many years, PAS 55 was the go to standard for good practices in Asset Management.  TWPL’s Managing Director, John Woodhouse, was the Project Director who led its development on behalf of The Institute of Asset Management (IAM). The last iteration was published in 2008 and involved over 50 organisations from 15 industries in 10 countries.

Several TWPL Principal Consultants contributed to PAS 55’s development and have been implementing, auditing and certifying against across different industries around the world.
