CI/CD is an automated chain where the idea is to involve as few human hands as possible, in order to avoid unnecessary manual work and error.
This doesnât mean that humans arenât involved in the process, of course. It just means that the chain should be able to run on its own, checking for errors and notifying testers and developers when something breaks or doesnât merge so that they can make changes much quicker than they would have been able to in a waterfall approach.
CI/CD goes hand in hand with DevOps and agile methodologies, as these all work towards a common goal of delivering quality at speed through flexible approaches
