Difference between structured,
semi-structured and unstructured decisions
Structured
decisions
Can be described as a
decision whereby all sections of a decision (data, process and evaluation) are
determined. This requires that this type of decision be routine, repetitive
making the process of dealing with it defined and specific. They are decisions
made in clear circumstances.
Unstructured
decisions
Although similar to the
structured decisions in terms of sections of the decision used there is less
agreement on which data and process to be used. The evaluation aspect of the
decision is also left to qualified individuals within the organization. This
type of decision leaves no room for premeditation of the procedures to be
followed and thus they are made in situations which are unclear and one-shot.
Semi

process and evaluation)
