Question
How does a continuous integration/continuous development (CI/CD) process help to reduce software failure risk?
A. Fewer manual milestones
B. Easy software version rollback
C. Automated software testing
D. Smaller incremental changes
Answer
D. Smaller incremental changes
Explanation
A continuous integration/continuous development (CI/CD) process helps reduce software failure risk in several key ways:
C. Automated software testing is a critical component of CI/CD that helps catch bugs, regressions, and other issues early in the development process before they make it into production. By automatically running a comprehensive suite of unit tests, integration tests, and other checks with each code change, CI/CD enables issues to be identified and fixed rapidly.
D. Smaller incremental changes are another key benefit of CI/CD. Rather than making large, infrequent releases that bundle many changes together, CI/CD encourages releasing small batches of changes frequently. This reduces risk by making each individual change smaller and easier to test and validate. If an issue does arise, it’s much easier to pinpoint the specific small change that caused it.
B. Easy software version rollback is enabled by CI/CD’s emphasis on automation and using version control for all artifacts. If a problematic change does get released, CI/CD makes it simple to redeploy the previous working version to quickly restore service while the issue is debugged and resolved.
A. Fewer manual milestones and approvals are required with a mature CI/CD process. Automated testing, code analysis, and other checks replace manual review gates in the release process. This reduces delays and the risk of human error.
In summary, a well-implemented CI/CD process significantly reduces software failure risk by catching issues early through automated testing, keeping changes small and incremental, enabling fast restoration of service via rollbacks, and reducing manual steps and human error in the release process. This allows organizations to deliver value to customers more quickly and reliably.
