Types of decision Management decisions can be classified into
two types – structured and unstructured. Structured decisions
– are repetitive, routine and involve a definite procedure for handling them.
Unstructured decisions– require judgement, insight and evaluation. They are
often important decisions and there is no set procedure for making them.

Desirable characteristics of a MIS They are flexible
– allowing for many different ways of analysing data and evaluating information They are capable of supporting a range of skills and knowledge They help managers get things done
– through interpersonal communication with other members of the organisation They should not require extensive periods of concentration
– because managers are busy people who switch rapidly between different tasks
They should make it easy to interrupt the work and return to it at a later time
They should protect a manager, as far as possible, from information overload.
