5.3.2 Contingency approach
The contingency approach recognises that problems can be categorised a number of different ways. Simon refers to problems on a continuum from well-structured to ill-structured (Simon 1973:181). A well-structured problem has identifiable procedures for its resolution: that is, the problem, when confronted, has a known methodology to resolve it. According to Mintzberg, an ill-defined problem involves a task requiring decision processes that have not been encountered in quite the same form and for which no predetermined and explicit set of ordered responses exists. (Mintzberg et al 1976:246)
The contingency approach led theorists to differentiate between programmed decisions to handle well-structured problems by providing routine and repetitive procedures and non-programmed decisions to handle a problem requiring a unique solution. Rules and policies predominate in programmed decisions thereby providing managers with a high degree of certainty about the appropriateness of the solution. In contrast, non-programmed decisions bring managers a high degree of uncertainty and therefore risk. The problem therefore requires both qualitative and quantitative solution methodologies to reduce the risk. When a manager solves a problem in isolation the risk is higher than when a manager enrols others to assist with the solution. The risk may be reduced by a factor associated with the increased number of people who participate in the problem solution. This is why some managers prefer to solve problems in a group situation. The advantages of group problem solving are:
- More complete information
- More alternatives are generated
- Acceptance of solutions are increased
- The legitimacy of the solution is increased.
The disadvantages of group problem solving are:
- Minorities can dominate (more powerful)
- Pressures to conform are applied by more powerful members
- Time consuming
- Responsibility for the solution is ambiguous.
The contingency approach has spawned two separate approaches to problem solving: qualitative approaches and quantitative approaches.
