Abstract
Context: In organizational psychology literature, Task Variety and Skill Variety are considered different aspects of work design. Albeit related to different aspects of the work, it is common to find strong correlations between these constructs. After applying the Work Design Questionnaire (WDQ) on a sample of 102 software professional, we found the similar correlations and conjectured that they were partly due to a misunderstanding about what a task is, what a skill is, and what could be considered a variety of those concepts in the practice of software development. Goal: Our goal in this study was to investigate the actual existence and the possible sources of such misunderstanding. Method: We performed semi-structured interviews with software professionals that had previously participated in the application of the WDQ and analyzed the results using qualitative research techniques. We selected four software professionals among those with higher experience in software development. Results: Qualitative data revealed insights regarding the reasons why the correlation identified in the quantitative results could have arisen in our sample. Conclusions: Our findings pointed out that the misunderstanding of such concepts might affect the results of the application of quantitative questionnaires that measure these constructs.
