A longitudinal case study on Nexus transformation: Impact on productivity, quality, and motivation

There have been success stories reported regarding the adoption of agile software development methods in the industry. There also exist observations on their limitations. One of these limitations is scalability since agile methods like Scrum were originally designed for small software teams. Scalable agile frameworks were introduced to address this limitation. We conducted an industrial case study on the adoption of such a framework, called Nexus. Our study involves quantitative and qualitative evaluation based on observations within a product development organization over a period of 12 months. Scrum is used for the development of a product during the first 6 months of this period. Nexus is used in the remaining 6 months. Data are collected throughout the whole period for measuring productivity, quality, and team member motivation. Results suggest a significant increase in productivity and product quality after switching to Nexus. Team motivation was slightly improved as well. An industrial case study is conducted for 12 months, where Scrum is used during the first 6 months and Nexus is used in the remaining 6 months. A significant increase in productivity and product quality is observed after Nexus transformation, while slight improvement is observed in team motivation as well.
