Scaling Collective Code Ownership and Code Review in LinkedIn - Nikolai Avteniev - Seguridad Mania.com - España y América Latina

The contemporary code review practice has been adopted by many organizations and open source projects as a quality assurance measure. This process typically involves software tools such as Review Board and the time of one or more peer reviewers. However, there is a growing body of empirical research about this broadly‐adopted practice that can help us learn more about the effects of code reviews on software quality. Available research shows that in fact, peer code reviews are better suited for knowledge sharing and code improvements, rather than for eliminating code defects or reducing error rates. The effectiveness of the process seems to depend on the experience of the reviewer with the code, the size of the change set, and the rate at which the review is conducted. In this talk, Nikolai will share how the LinkedIn Flagship Product Engineering team leverages the code review process to spread organizational knowledge and uplevel individual contributors. I will also discuss the tools we’ve built to support this practice across a team which spans three offices, four development stacks, dozens of teams, and hundreds of individual contributors.
