The effects of development process modeling and task uncertainty on development quality performance

We examine the impact of development process modeling on outcomes in software development projects, limiting our attention to process and product quality. Modeling the software development process requires a careful determination of tasks and their logical relationships. Essentially, the modeling is undertaken to establish a management framework of the project. We define and interrelate development process modeling, task uncertainty, and development outcomes, as assessed by product and process quality. A survey-based research design was used to collect data to prove our model. The results suggest that development process modeling is positively related to both product and process quality, while task uncertainty is negatively related to them. Development process modeling reduces the negative impact of task uncertainty on quality-oriented development outcomes. Development projects operating with high levels of task uncertainty should consider defining development process models that provide a framework for management of the project by establishing tasks and their logical interrelationships. Such a model should promote shared understanding of the work process among development constituents and enhance resource utilization efficiency.
