Agile and DevOps: Your Questions. Our Answers.

April 2018 Webinar
Hasan Yasar, Eileen Wrubel

Watch this lively discussion in which we answered attendee questions on all things Agile and DevOps.


Software Engineering Institute



Meeting business needs and adapting to the speed of the market for new features requires an agility mindset and continuous-delivery techniques throughout application-development lifecycles. Many believe that Agile means Scrum and DevOps means continuous deployment. Agile and DevOps can make these terms sound very different. However, Agile is more about process and methodology whereas DevOps focuses on how to reduce time to market with automation mechanics. These approaches are generating more and more questions in DoD environments with respect to regulation and security on large-scale programs. Do they complement each other? Is there any relationship between them? Should one be done before the other?
