The Effect of Sprint Duration to the Velocity in a Large-Scale Embedded Software Project
Dong Seon Park, Ji Young Noh · 2023
Background: Since there are not many empirical studies on the effect of sprint duration on efficiency and productivity in large-scale agile software developments, we collected and analyzed data from large-scale embedded software development. Aim: Our objective is to analyze the effect of sprint duration on the velocity in scrum-based software development projects. Method: We selected five scrums with the least changes from a large-scale embedded software development project of a big company and measured the change in velocity when operating with 3-week and 2-week sprint durations under the same condition. Results: Our analysis revealed that the 2-week sprint duration had about 30 percent higher development velocity. The average velocity was analyzed in four milestones over about two and half years of period, and the one-tailed T-test with an assumption of unequal variances proved that the development cycle of a 2-week sprint duration was higher than that of a 3-week sprint duration. Conclusions: In this respect, this paper contributes to improving the productivity in large-scale embedded software projects.
