PC's, Central-System Computing, and Government Functionality

In this article, the authors use correlational methods to prove their point-of-view. The way that this is accomplished is through a survey. They used percentages comparing two sets of subjects as well as a statistical analysis based on Cramer V scoring. The importance of the correlation was based upon whether or not the values in the study were greater than.20 on the Cramer V scale. If the score was under.20 it showed a weak relationship, while scores greater than.20 on the Cramer V scale showed a moderate relationship.

The authors address the computing problem quickly. The problem being the widespread belief that PC's can easily and cheaply replace mainframe computers in governmental operations (page 1, paragraph 3, lines 1-4). The problem itself was deduced from research studies completed over the last decade and is answered by the study conducted by the authors. The objective of the study is stated as, "Our aim is to assess whether the two computing environments are functionally equivalent, as many of the PC advocates would have it, or whether PC-only environments provide only some of the functions, applications, and benefits of their bigger brothers and sisters -- the mainframe and minicomputer environments" (page 2, paragraph 3, lines 1-4).

The scope of the study conducted by the authors clearly addresses all of the concerns raised in the article. However the population of this study is defined as, "...two sets of cities..." (page 2, paragraph 4, line 1). The description of this population is very vague in that there is no clear definition as to the size of the cities involved. It is impossible for the reader to know whether this study is based on small cities or a large metropolis. The population used in studies referenced by the authors range from small to medium cities, but no reference is made as to whether or not the authors used the same size population in their own study. The authors specify the sampling of this study to be, "Assistant managers, department heads, technical staff, and administrative staff..." (page 4, paragraph 3, line 3), and referred to studies used for comparison.....
