Problem-contexts, it followed, could also exhibit a 'unitary' or 'pluralist' character. Bringing the two dimensions of 'systems' and 'decision- makers' together, to form a four-celled matrix, yielded a classification of problem-contexts as mechanical-unitary, systemic-unitary, mechanical-pluralist and systemic-pluralist. Some brief justifi- cation was provided for the choice of the two dimensions forming the matrix. | Problem-contexts, it followed, could also exhibit a 'unitary' or 'pluralist' character.

mechanical-unitary contexts classical OR Systems analysis and systems engineering are most appropriate for solving problems. It is taken as given that it is relatively easy to establish clear objectives for the system in which the problem resides so the context must be unitary. They then try to represent the system in a quantitative model which simulates its performance under different operational conditions something only possible if the system is simple and the context mechanical. | |||
Cybernetic approaches, such as advocated by Beer and in the socio-technical systems literature | |||
Suitable for tackling problems associated with systemic-unitary contexts. | |||
Mechanical-pluralist contexts responded to the kind of systems design method proposed by Churchman, and by Mason and Mitroff in their 'strategic assumption surfacing and testing' methodology. | |||
The soft systems thinking proposed by Ackoff and by Checkland could minister to problems set in systemic-pluralist problem-contexts. For example, Ackof's 'interactive planning' exhibited, through the participative principle, a method to cope with pluralism and, through the proposed design for a 'responsive decision system', an attempt to come to terms with systemicity | |||
