5. 在資訊系統中的五種理論類型 • Application of the Taxonomy • The taxonomy was used to classify 50 research articles in two leading journals to demonstrate its applicability • Issues of MIS Quarterly and Information Systems Research from March 2003 to June 2004 were used as the source of the articles. • All articles except issues and opinions, review articles, and research essays were included in the classification process.

6. 在資訊系統中的五種理論類型 • Classification was performed by the author and a junior researcher independently, using the distinguishing attributes in Table 2 as the primary basis for decisions to assign an article to one of Types I to V. • The purpose of this classification activity was not to determine the relative frequency of publication of different theory types, but to test on a small scale whether the classification schema is (1) exhaustive, (2) understandable, and (3) does not have unnecessary categories.

7. 在資訊系統中的五種理論類型 • The activity showed that the schema appears to be exhaustive: no papers were found that could not be classified under the schema • The decision rules to allocate theory to a category appear to be understandable, as the junior researcher was able to apply them independently and arrive at similar conclusions to the author.

8. 在資訊系統中的五種理論類型 • The question arises as to whether the Type III category is really necessary. • Only one article was found with theory that fell into category III: prediction without causal explanation. • It is believed that this category should be retained, even if instances in this class are few, both for analytic completeness and as it is a type of theory recognized by a number of authors.
