Scaled Agile Framework - SAFe Sherwin-Williams & Dev. Ops

Dev. Ops “You keep using that word. I do not think it means what you think it means” -Inigo Montoya (The Princess Bride) Sherwin-Williams & Dev. Ops

◆ Efficiency - Faster time to market ◆ Predictability - Lower failure rate of new releases ◆ Reproducibility – Version everything ◆ Maintainability - Faster time to recovery in the event of a new release crashing or otherwise disabling the current system Break down the wall between development and operations Sherwin-Williams & Dev. Ops Image from - dev 2 ops. org Why Dev. Ops?

Dev. Ops is not … Separate Silos Dev Sherwin-Williams & Dev. Ops

Dev. Ops is not … Separate Dev. Ops Silo Dev Sherwin-Williams & Dev. Ops Ops

Dev. Ops is not … “We Don’t Need Ops” Dev Sherwin-Williams & Dev. Ops Ops

Dev. Ops is … Smooth Collaboration Dev Sherwin-Williams & Dev. Ops

Dev. Ops is … What is Dev. Ops? It’s not a team or title … it’s a pipeline. Sherwin-Williams & Dev. Ops

Dev. Ops is … More collaboration and automation between the development and operations teams = larger pipeline Sherwin-Williams & Dev. Ops

Dev. Ops is … Remove the hand offs – streamline the process, challenge everything that doesn’t add value. Sherwin-Williams & Dev. Ops

Dev. Ops One team cannot do it all … Must be a joint collaboration effort! Sherwin-Williams & Dev. Ops Code Environments Data Tests

Development + QA + Performance Testing everything, automatically and at all tiers is critical to moving at the speed of light. Sherwin-Williams & Dev. Ops Tests

Quality Engineer ◆ Provide guidance for test automation to the feature teams as they develop tests wrapped around features/stories and ensure test coverage. ◆ Design framework to embed testing into CI process. ◆ Provide design and guidance for mobile and browser testing. ◆ Provide support to the systems team to ensure code, environment, data and test management. ◆ Develop, implement and maintain system integration, end-toend, smoke, and regression tests for the over arching functionality being delivered. Sherwin-Williams & Dev. Ops

Performance Engineer ◆ Provide guidance to teams with gathering/creating NFRs for features/stories. ◆ Design/provide guidance to design a reliable and repeatable performance test integrated with CI to measure NFRs and gather performance trends across features. ◆ Work with/enable teams to troubleshoot performance issues by tooling for monitoring and analysis. ◆ Support system demos by defining system level NFRs and designing the performance tests to validate those NFRs.

Development + CM + DBA Create reproducible databases and data extracts just like application code … but it’s a lot more complex. Sherwin-Williams & Dev. Ops

Development + CM + DBA Why database migrations? ◆ What state is the database in on this machine? ◆ Has this script already been applied or not? ◆ Has the quick fix in production been applied in test afterwards? ◆ How do you set up a new database instance? Sherwin-Williams & Dev. Ops
