Lead time analysis for code changes in a large-scale telecom development environment : An Ericsson case study

In this study, we investigate how lead time is affected during development of a large-scale telecom product. We collected raw data from the product’s Gerrit repository which were later processed with statistical analysis. When we analysed the various areas, we concluded that a method to divide the lead time into different sequences would be the preferred method. We therefore chose to analyse lead time for different parts of the development. We found that on average lead time is roughly 3,4 days for the areas we investigate. The results indicated that lead time for reviewing increases with the years. The results also indicated that the lead time decreases for developers as they become more familiar with the product however the overall lead time for implementation did not. This can be as developers switch tasks internally or decides to change employment. The results also indicated that there is no relation between the amount of submitted LOC and lead time.
