EXIN DevOps Professional case studies
EXIN DevOps Professional · Put your knowledge to work in context.
The EXIN DevOps Professional credential is intended for practitioners who work where development and operations meet: engineers, release and operations staff, testers, and team leads who want to show they understand how DevOps practices change the way software is delivered. Candidates usually arrive with some hands-on delivery experience rather than purely theoretical knowledge, because the exam tests judgement about flow, feedback, and organisational change as much as definitions. The exam is structured around four equally weighted domains: DevOps practices covering flow, feedback and continual learning; DevOps culture and organisational change; automation and tooling; and measurement, metrics and resilience. Each domain carries 25 percent of the total, so a candidate cannot compensate for a weak area by over-performing in another. The EXIN DevOps Professional case studies are 5 cases and about 3,542 words.
