- Excessive software development is the tendency to develop new software above and beyond the requirements of the market and/or planned specifications. It is a widespread phenomenon involving both risks and flexibility advantages. As it represents a challenging dilemma for software developers, it is important to study its human origins. Drawing on the tripartite model of individual attitudes, this study investigates the influence of developers’s cognitive (intuitive and rational thinking styles), affective (emotional attachment) and behavioural (reliance on past experiences) traits on two forms of excess, beyond needs and beyond plans. Using survey data on 307 software developers, this study shows that different manifestations of excess are associated with distinct traits of software developers. Emotional attachment drives beyond needs excess. A positive (negative) association is found between relying on past experiences and beyond needs excess (beyond plans excess). An intuitive cognitive style fosters the inclusion of extra features in the new product scope, whereas a rational style might lead to developing one-size-fits-all software that targets the needs of a broad user base. These findings contribute to research on the development of digital new products and production technologies by offering a comprehensive yet fine-grained picture of excessive software development’s nature and drivers.

- This exploratory study investigates the relationship of plan-driven Stage-Gate and flexible Agile models with new product development performance through an original conceptualization that focuses on their underlying principles for managing uncertainty and the resulting changes. While Stage-Gate attempts to control uncertainty up-front to avoid later changes, Agile seeks to adapt to uncertainty and accommodate changes for a longer proportion of the development process. In addition, we examine the interaction effects of combining the two models. The analysis of survey data on 181 software developers shows that the adoption of Stage-Gate principles is negatively associated with speed and cost performance. For Agile, the use of sprints is positively related to new product quality, on-time and on-budget completion, while early and frequent user feedback would seem to prolong time-to-market. Finally, the results highlight a nuanced interaction between Stage-Gate and Agile, both positive and negative depending on the principles considered.
