On CASE tool usage at Nokia

Abstract

We present the results of a research work targeted to understanding CASE tools usage in Nokia. By means of a survey questionnaire, we collected data aimed to identify what features are most useful and best implemented in current CASE tools according to senior developers and managers. With the aid of both descriptive and inferential statistical data analysis methods, we found out that the features that are rated most useful belong to the graphical editing, version management and document generation categories. The statistical methods we use allow us to extend the results to the whole population with a certain degree of confidence. The analysis of the data seems to give the indication that there is a general level of dissatisfaction on the quality of currently available CASE tools. Also, there is evidence that some of the most advanced features (reverse engineering, code generation) are not deemed as useful as others. Further research should focus on extending the survey to other types of industries, and attempt generalization of the results. This may constitute precious feedback for the software tools industry in order to develop products that correspond more to industry needs.
