Continuous integration (CI) is a software engineering practice where developers frequently integrate their work, leading to multiple integrations per day. This approach reduces integration problems and allows teams to develop cohesive software more rapidly. The presentation discusses what CI is, why teams need it, prerequisites like version control and automated testing, typical workflows, tools, and benefits like reduced risks and improved code quality. It also examines problems teams face in implementing CI effectively and potential areas of future research like making CI tools more adaptive and addressing scalability issues.
