In previous papers (Stewart, 1989, 1999a, 1999b) he had proposed a new, ternary concept of mechanism, which forms the basis of a new paradigm for purpose and directiveness. One practical outcome of this is an analytic technique-Ternary Analysis. This, among other things, enables any particular kind of human work to be analysed into one or more of three components. One thing that Ternary Analysis does is to clarify the place of evaluation and judgement in work. Another is to suggest the stages to be followed in the design and construction of work and tasks, to arrive at ternary mechanisms that will achieve the desired results (Stewart, 1999c). It also offers a way of designing human institutions to use the human beings composing them more appropriately. It shows how to design a working environment that is divided horizontally into departments, each of which is concerned with a particular dimension of imparity. It also shows how a Law of Sum of Intervention Ratios operates in the vertical structure of such a working environment, and indicates where we should expect to be able to fit computer-based systems into human institutions, and where the human beings are best placed (Stewart, 1999d).
