Three Practices for Effective DevOps Adoption

Three Practices for Effective DevOps Adoption

A couple of years ago, Endava realized that the difficulties in DevOps adoption are never the automation technology but rather the ways-of-working, which require a much more fundamental change in people's behavior and culture. Over time we found that there are three practices that have been repeatedly useful in helping successful DevOps adoption.

The practices are (real) agile development, incubator teams and pipelines. In this talk, Eoin will briefly review all three, discuss why they facilitate successful DevOps adoption and talk in a bit more depth about incubator teams, which may be less familiar to attendees than the other two.

    EOIN WOODS // 20200915.1 ENABLER TEAMS DevOps implementation is difficult … and it’s never a technology problem (really) There is a lot to learn … and a lot of culture to instil … and a lot of behaviour to encourage Enabler Teams are one way we’ve found to help with this
  20. GOTOpia 2020 // THREE DEVOPS PRACTICES // © COPYRIGHT 2020

    EOIN WOODS // 20200915.1 20 ENABLER TEAMS Enabler teams work as peer-team within the overall engineering team to: • Develop culture by example • Bring and transfer technical knowledge • Build useful shared things that make everyone more productive
  21. GOTOpia 2020 // THREE DEVOPS PRACTICES // © COPYRIGHT 2020

    EOIN WOODS // 20200915.1 21 SOME ENABLER TEAM MODELS Nurturing Expert team working with all scrum teams to foster practice & transfer knowledge. Once DevOps ways of working embedded, dissolve into teams or move on Technical expertise team goaled with bounded task to unblock transformation (e.g. “fix the tests”) Fixing Form the team, fix the problem, evangelize approach, transfer knowledge, dissolve Team that demonstrates DevOps working by delivering and owning an enabling shared source “product” (pipeline, deployment platform, …) Building Long standing team, membership rotating through scrum teams

    EOIN WOODS // 20200915.1 Some Practices to Consider • Get agile working first • Look for evidence of outputs not ceremonies • Small regular deliveries provide DevOps inputs Agile Working Pipelines • Pipelines provide reliability, efficiency, consistency, … • Shared tools lead to collaboration (perhaps surprisingly) • Useful for non-technical stakeholders too once visualised Enabler Teams • A lot to learn for any team • Develop culture, transfer knowledge, build useful things • Dissolve or rotate staff frequently
