ABSTRACT
Human factors and ergonomics (HFE) testing brings out both the best and worst of the human factors and ergonomics disciplines. At its best, HFE testing brings knowledge and methods out of the laboratory and places them in the hands of the general population in the form of tools, processes, and systems that are effective, efficient, intuitive, and easy to use. At its worst, HFE testing can represent a battleground where the competing interests of developers and users, scientists and engineers, designers and financial managers, are locked in conflict over the cost, implementation, and even the purpose of testing system designs.
