Maintaining Review Quality in Distributed Teams is a Challenge

Challenge

As remote and globally distributed development teams are becoming commonplace, we are faced with the challenge of maintaining a consistent code review quality. Different teams can have different practices, coding standards, tooling, and expectations for reviews. This makes it unlikely that code review practices will be the same or at least equivalent across all teams. And with time zone differences, real-time collaboration is just not possible, meaning the review process can often take additional time rotating between members. Language barrier issues can also have additional impact; as local practices do tend to differ from one language to another even when they share a somewhat common practice. Without centralized governance, accountability, and by utilizing time-consuming manual processes there is no guarantee that all team members and their efforts to adopt best practices and local guidelines will be effectively managed or maintained.
