Continuous integration (CI) is a practice that involves frequently integrating code changes into a shared repository, allowing teams to detect and resolve issues early. In the context of the scenario, where delays occur due to developers using individual repositories, CI would help by enabling regular integration of code, reducing conflicts, and streamlining the development process. This aligns with the ITIL 4 Specialist: Create, Deliver and Support guidance on optimizing value streams through effective planning and building practices.
The official ITIL 4 CDS study guide (Section 2.2.1) emphasizes that CI reduces delays by automating integration and testing, which is critical when managing service creation and changes. Other options like continuous delivery (B) and continuous deployment (C) are subsequent steps that build on CI, while continual improvement (D) is a broader practice not specifically addressing the repository issue.
