Systematic analysis of the incremental process as a base for comparison with the Agile process

Background: The number of studies that quantitatively reveal the effect of using Agile models on development performance is scarce. Aim: In this paper, we explain the analysis of a plan-driven. Incremental Process within Siemens EC. carried out to understand its performance as a base for the comparison with the Agile Process. Method: We introduce a method to systematically analyze a software development process to understand its performance quantitatively, and explain the application of the method on the System Test phase of the Incremental Process. Results: The utilization of the analysis method practically contributed to the implementation which was completed in 8 person-days. An analysis of derived measure values indicated that there was no outlier value in the interval of mean ± 3 standard deviation for the measures. Conclusions: We expect that the method will be more beneficial in capturing the context of the Agile Process and its measures.
