Description
RubyConf AU 2016: Some of us have practiced code review as part of our software development process. But it is more than just a peer review of code written by another. I will attempt to summarise some of the good practices that worked for us to review code effectively and some of the common mistakes not to make when setting out a code review programme for your team.

The video, titled "Code Review: Pitfalls and Good Practices," presented by Thong Kuah at RubyConf AU 2016, explores the significance of effective code review practices in software development. The focus of the discussion is on the cultural aspects of code review rather than merely technical checklists, emphasizing how a positive environment can lead to better code quality and team satisfaction. Key points discussed include: - **Importance of Code Review**: Code reviews are crucial not only for identifying errors but also for nurturing a positive team culture and enhancing developer satisfaction. - **Cultural Focus**: The speaker stresses the need to get the right culture in place before delving into technical practices, as a supportive environment leads to better outcomes. - **Initial Challenges**: The team faced significant challenges in 2015 when their project suffered delays, compounded by large, risky code changes. - **Review Process Changes**: - Transitioning from end-of-task reviews to more frequent, task-based reviews to reduce bottlenecks. - Encouraging team-wide participation in reviews, allowing junior members to contribute valuable insights. - **Mandatory Reviews**: Implementing strict code review requirements improved overall code quality. - **Defining ‘Done’**: Establishing clear criteria for what constitutes completion helped to reduce unnecessary feedback. - **Incremental Code Changes**: Breaking down large projects into manageable chunks allowed for timely feedback and reduced stress during releases. - **Engagement with All Team Members**: Involving the whole team in code reviews created a learning culture and brought varied perspectives, which helped catch mistakes often missed by more experienced developers. - **Collaborative Review Practices**: The introduction of a collaborative model where team members review each other’s work encouraged comprehensive feedback and fostered relationships within the team. - **Role of Testers and Review Managers**: Testers and a release manager were essential for quality assurance, providing additional layers of scrutiny before code deployment. Ultimately, the team saw marked improvements in their sprint performance and happiness, which led to their practices being adopted by other teams within the organization. Thong encourages viewers to reflect on their own code review processes to enhance team productivity and satisfaction.
