Explain the difference between structured and unstructured
decision-making. Provide examples of each in terms of a business with
which you are familiar. Are information systems better suited for
structured or unstructured decision-making?

Structured decision are pre-specified by a set of rules or decision
process, they reflect in rule book, decision tables or regulation
table. Programmed decision imply decision making under certainty since
condition must be known and can be delegated to lower lowel for
decision making..

As opposed Unstructured decision has no pre-established procedure,
they are not reflected in any books, it is decision making under risk
since conditions keep changing, and lastly these decisions are
deligated to high level decision making.

Ex.: Structured: Purchase of material by a company.
Unstructured: Purchase of clothes by Women :-) 

Information system are better suited to structured decison making. For
unstructured decision making expert systems are better.
