Several viewpoints on information systems illustrate that the study of information systems is a field with multiple disciplines and therefore, no single theory or perspective governs. In most cases, the field can be separated into behavioral and technical approaches. The behavioral approach can be broken down even further into sub-categories to add economics, psychology, and sociology. The technical approach can even be divided into sub-categories to add management science, computer science, and procedures research. A very important aspect of the information systems field is involved with behavioral conditions that surface in the development and preservation of information systems. Problems like strategic business design, implementation and utilization, and management cannot be fully explored with the models by using a technical approach.
