Peer Code Review “Latest” Statistics

  • Capers Jones’ ongoing analysis of over 12,000 software development projects showed that the latent defect discovery rate of formal inspection is in the 60-65% range.[1]
  • According to a 2012 research by VDC Research, automated methods for peer code review are now used by 17.6% of the surveyed embedded software developers, and 23.7% plan to utilize them in the next two years.[1]
  • Empirical studies provided evidence that up to 75% of code review defects affect software evolvability/maintainability rather than functionality, making code reviews an excellent tool for software companies with long product or system life cycles.[1]
  • In a specific company, it was noted in 2015 that 75% of code review feedbacks are provided by team authors, despite being marginally less helpful than feedback from other teams.[2]
  • According to Bosu (2015), some projects the proportion of relevant comments decreased by 10%, when they compared changes in 40 files with changes in a single file.[2]
  • 96% of participants think patches with more LOC have a negative impact on duration.[2]
  • 29% of the participants think that patches with more LOC get fewer comments, while 49% disagree and say that patches with more LOC receive more comments.[2]
  • 97.8% of the participants reported medium to very high experience with projects with multiple teams, whereas 93.3% reported medium to very high experience with projects with multiple locations, suggesting that they have experience in DSD.[2]
  • The most intriguing findings, according to McConnell, are that no technique’s modal rate exceeds 75% and that the approaches’ average efficiency is about 40%.[3]
  • According to several estimates severe bugs are 100 times more expensive to fix after shipping than they are to fix before shipping.[3]
  • According to Basili and Selby, code reading found 80% more defects per hour than testing, even when evaluating programmers on code with no comments. Inspections are often a less expensive way to uncover flaws than testing.[3]
  • If aforementioned four categories was simply used, the best bug discovery rate will be 68%.[3]
  • The SmartBear study of Cisco Systems found that “spot checking” 20% to 33% of the code resulted in lower defect density with minimal time expenditure.[4]
  • The SmartBear study of Cisco Systems found that lightweight code review takes less than 20% the time of formal reviews and finds just as many bugs.[4]
  • Despite the fact that the majority of my students were upper level computer science majors, 63% of them admitted at the beginning of the semester that they had never used git.[5]
  • According to a 2017 study of 240 development teams, 90% of the teams employ a review procedure based on changes, and 60% use frequent changes.[6]
  • 96% of the participants believe that duration is negatively affected by patches with a higher number of LOC.[6]
  • A study of an organization at AT&T with more than 200 people reported a 14% increase in productivity and a 90% decrease in defects after the organization introduced reviews.[7]
  • In a software-maintenance organization, 55% of one-line maintenance changes were in error before code reviews were introduced.[7]
  • The Aetna Insurance Company found 82% of the errors in a program by using inspections and was able to decrease its development resources by 20%.[7]
  • 95% of the modifications following the introduction of reviews were accurate the first time, when all changes were taken into account.[7]

How Useful is Peer Code Review

In today’s ever-evolving technological landscape, the importance of peer code review cannot be overstated. Software development projects have become more complex and are often developed by teams rather than individual developers. As such, having multiple sets of eyes review code can help catch mistakes, optimize performance, and ensure that the software being developed is of the highest quality possible.

One of the main benefits of peer code review is the ability to catch errors before they make their way into production. Software bugs can be costly and time-consuming to debug once they reach your customer base. By having peers review code, potential issues can be caught and resolved early on in the development process, saving time, money, and frustration down the road.

In addition to catching errors, peer code review also provides an opportunity for knowledge sharing and growth. Developers can learn from each other’s coding styles, techniques, and best practices, leading to a more cohesive and skilled team. Peer code review fosters a collaborative environment where developers can help each other improve their skills, ultimately benefiting the entire team and the quality of the software being developed.

Furthermore, peer code review can lead to better code quality overall. By having multiple team members review code, different perspectives and insights can be shared that may not have been considered by the original developer. This can lead to code that is more efficient, easier to maintain, and ultimately, more successful in meeting the needs of the end-users.

While peer code review is incredibly valuable, it is important to note that it does have its limitations. Peer code review is not a replacement for thorough testing or other quality assurance processes. It is just one piece of the puzzle when it comes to developing high-quality software.

In conclusion, peer code review is a valuable tool in the software development process. It allows for errors to be caught early, promotes knowledge sharing and growth, and ultimately leads to better code quality. In an industry where technology is constantly changing and evolving, having multiple sets of eyes on code is essential to ensuring that the software being developed is of the highest quality possible. Peer code review may take time and effort, but the benefits far outweigh the costs. It is an essential part of the software development process and one that should not be overlooked.
