Asset Management Maturity Scale and Guidance


The Asset Management Maturity Scale and Guidance is an introduction to asset management maturity, and how it can be defined, scaled and recognised. It contains a generic maturity scale, ranging from Innocence to Excellence, along with definitive attributes and symptoms you might expect in each of the 39 subject areas of the Asset Management Landscape.

The development of consensus and standards within the discipline of asset management creates a need for a scale of capabilities and maturity against which organisation can identify their strengths and areas for improvement. This scale serves to diagnose and prioritise the development of new capabilities, benchmarking and demonstrating progress, competency or excellence to stakeholders. 

It also serves to establish processes and habits of continual improvement with an objective basis of evidence across the many dimensions of asset management.


This guide is the cumulative product of several IAM studies of the subject over 12 years, ranging from the scale developed for the BSI PAS 55 specification, to the gap analysis and conformance assessment against ISO 55001 (the Self-Assessment Methodology). All cases involved multi-industry collaboration projects with extensive consultation and peer review within the IAM’s diverse membership.

Nevertheless, this guidance is inevitably a work in progress. The subject of asset management and the characteristics of best practice are continually evolving, through process innovations, new technology and learning. There are also widely different operational environments, constraints, cultures and opportunities in asset management, so what should be recognised as ‘competent’ or ‘excellent’ needs to consider the context of the organisation and how this changes. Such context-dependencies have been explored to an initial level in this guide, but we expect many further insights, experiences and refinements to emerge over the coming months and years.
