Abstract
While cognitive ergonomics has undoubtedly imposed itself as a scientific discipline, it is still only applied in an approximative fashion by consultant ergonomists in their day-to-day work of analysing and improving socio-technical systems. The cognitive analysis of work often draws more on the intuition derived from operators' cognitive activities than from the results of rigorous methodological approaches. From my point of view, this hampers the expansion of cognitive activity as a vehicle for transforming socio-technical systems. Developing practical means (techniques and methods) for applying cognitive ergonomics is thus a challenge we have to face for the future, if this discipline is to contribute fully to the improvement of working systems on a daily basis.
