Gives taxonomy for FM which includes: - relevant interrelationship of elements and their structures in FM; - definitions of terms and contents to standardise facility products which provide a basis for cross border trade, data management, cost allocation and benchmarking; - a high level classification and hierarchical coding structure for the standardised facility products; - expanding the basic FM model given in EN 15221-1 by adding a time scale in the form of the quality cycle called PDCA (Plan, Do, Check, Act); - a linkage to existing cost and facilities structures; and - alignment with the primary activities requirements.
