Identify bottleneck(s)Business Customer Value Stream Mapping

where’s the bottleneck? HR MGMT FINBusiness SALES DEV OPS Customer .....

In Dev & Ops ? HR MGMT FINBusiness SALES DEV OPS Customer .....

Or elsewhere? •Do you have the correct Hiring Policy? (HR) •Are you overselling? (Sales) •Correct Financial Icentives? (FIN)“devops” bottlenecks can live outside dev or ops

“Devops Areas”a way to ‘categorize’ practices

Culture AutomateDEV OPS Measure Share http://www.opscode.com/blog/2010/07/16/what-devops-means-to-me/

Area 1: Extend delivery to production ‘think Jez Humble” Area 1DEV OPS

Area 1: Extend delivery to Production • Ability to rebuild your production from source • Infrastructure as code • Version controlled • Reuse across dev, test, prod Tools Faster feedback on production issues

Area 1: Extend delivery to Production• Visualize production work done • Track production tasks (Kanban, Scrim) • Time spent on production issues are put on the sprint backlog Process Better estimates and feedback on effort

Area 2: Extend operations feedback to project think “John Allspaw” DEV OPS Area2

Area 2: Extend operations feedback to project • make monitoring, logs, metrics available to project to see information • give access to production systems Process ToolsSelf service the ability to ‘see’ prod

Area 2: Extend operations feedback to project • blameless postmortems together with dev • root cause analysis • identify recurring problems People ProcessIntegrate feedback to avoidsame mistakes

Area 3: Embed Project knowledge into Operations Area 3 DEV OPS

Area 3: Embed project knowledge into operations • Devs wear pagers for production • After a release, devs stay responsible for X months for all alerts People ProcessTake production experienceback to avoid things earlyin the process

Area 4: Embed Operations knowledge into Project DEV OPS Area 4

Area 4: Embed operations knowledge in project • Ops are part of the project team • Attend stand-ups • Work on backlog issues • Part of planning meetings People ProcessEarly feedback by prevention

Area 3: Embed Project knowledge into Operations Area 1: Extend delivery to productionDEV OPS Area 2: Extend operations feedback to project Area 4: Embed Operations knowledge into Project

“Areas” vs “Steps” non-prescriptive: you can start in any area location ofyour bottleneck/solution may vary

“Layers per Area” Can you ‘technically’ ToolsArea X do it Process Should you do it People Will you do it (culture) things you do in an area (think ‘tags’)

With great power comesgreat responsibility Voltaire

Area Maturity Level a way to track your journeyhttp://groups.google.com/group/devops/browse_frm/thread/f3de603a4cea493e?scoring=d&

CMMI Maturity Levels (Process Centric) Unpredictable Initial poorly controlled and reactive Focused on project, often Managed and reactive Focused on organization and Deﬁned proactive Quantitatively Managed Measured and controlled Focus on Optimizing Improvement

“Alternative Maturity Levels” (cfr. Continuous Integration Model) Intro Using Source Control ... Builds Triggered by Novice Commit ... Automated Deployment Intermediate to Testing ... Automated Functional Advanced Testing ... Continuous Deployment Insane to Prod ...http://blogs.urbancode.com/continuous-integration/continuous-integration-maturity-model/

Just don’t fool yourself Me and many others

Faster and better feedbackDEV OPSSmaller and more frequent changes

Speed indicatorsDeploy Change Requests People involvedper day per day per deploy People Tools Process

How fast can you ? vsHow fast do you want to go ?

Area 1: Extend delivery to Production• A new developer can deploy to prod from day1 • We are conﬁdent our tests will stop him • We trust people to do the right thing Process At the insane level, really?

Tests are the brakes thatmake us go faster

The new bottlenecks• Testers (QA)• Risk Control (Security)• Standardize and automate• Use human knowledge ‘embedded’ in teams• Peer reviews• Flag areas of risk for review

The networking modelNewspapers control Silos Cross functionalSocial Media sharing teams

Deploy vsRelease

“Canary” releases“Dogfooding” environments

Mean Time Between Failureis an outdated metric

Mean Time To Recoveris the new gold

How fast can you respond?
