Ergonomics has traditionally taken a 'systems' approach, and has considered the role of people within a system and stakeholders external to it. Recent developments in systems engineering, notably the development of ISO/TEC 15288, have provided a project environment that sets out to support the application of ergonomics. The ergonomics contribution to system development and operation has been defined by the Human-Systems (HS) model, currently with ISO to be published as a Publicly Available Specification. The HS model is a significant expansion of the successful standard ISO TR18529, moving from an interactive product to a full system. The model has a number of differences from more traditional descriptions of how ergonomists go about their work. The ability to produce such a model indicates a maturing of the profession, with all the opportunities that standardisation brings with it. It also offers opportunities to define practitioner competence within accepted frameworks.
