Why It Matters
Pull requests are the quality gate between writing code and shipping it. They ensure that no single person’s changes go live without at least one other set of eyes checking them. This catches bugs and enforces coding standards. It also spreads knowledge of the codebase across the team. For business owners, pull requests are a sign that your development team has a structured process. Changes are deliberate, reviewed, and traceable. If a feature causes a problem after launch, the pull request provides a clear record of exactly what changed and who approved it.
Example
Your development team is adding a discount code feature to your e-commerce site. A developer builds the feature over several days, then opens a pull request describing the changes and linking to the original brief. A senior developer reviews it, spots that the discount could be applied twice if a user clicks fast enough, and leaves a comment. The original developer fixes the issue and updates the pull request. Once approved, the changes are merged and deployed, and the double-discount bug never reaches your customers. The same review process applies across our web application development work.
