Editing Code review (section)

=== Regular change-based code review (Walk-throughs) ===
Software development teams typically adopt a more lightweight review process in which the scope of each review is on the changes to the codebase performed in a ticket, user story, commit, or some other unit of work.<ref name="rigby2013fse">{{cite book |last1=Rigby |first1=Peter |title=Proceedings of the 2013 9th Joint Meeting on Foundations of Software Engineering |last2=Bird |first2=Christian |date=2013 |isbn=9781450322379 |pages=202–212 |chapter=Convergent contemporary software peer review practices |citeseerx=10.1.1.641.1046 |doi=10.1145/2491411.2491444 |s2cid=11163811}}</ref><ref name="baum2017profes" /> Furthermore, there are rules or conventions that integrate the review task into the development workflow through conventions like mandatory review of all tickets, commonly as part of a [[pull request]], instead of explicitly planning each review. Such a process is called "regular, change-based code review".<ref name="baum2016qrs"/> There are many variations of this basic process.

A 2017 survey of 240 development teams found that 90% of teams using code review followed a change-based process, with 60% specifically using regular change-based review.<ref name="baum2017profes"/>
Major software corporations known to use changed-based code review include Microsoft,<ref name="macleod2017ieee">{{cite journal |last1=MacLeod |first1=Laura |last2=Greiler |first2=Michaela |last3=Storey |first3=Margaret-Anne|last4=Bird |first4=Christian|last5=Czerwonka |first5=Jacek|title=Code Reviewing in the Trenches: Challenges and Best Practices |journal= IEEE Software |volume=35 |issue=4 |pages=34 |date=2017 |doi=10.1109/MS.2017.265100500 |s2cid=49651487 | url=https://www.michaelagreiler.com/wp-content/uploads/2019/03/Code-Reviewing-in-the-Trenches-Understanding-Challenges-Best-Practices-and-Tool-Needs.pdf | access-date=2020-11-28 }}</ref>
