2. Who are we? Christian Trabold Consultant at ThoughtWorks Vinh Duc Bach Sy Developer at ThoughtWorks
3. How often did you give a gift that made the other person happy? How often did the gift not make happy? What makes you feel better? Before we begin…
7. 60%–90% of ideas do not improve the metrics they were intended to improve.
8. Feature & Delivery Pressure 1/3 of ideas created a statistically significant positive change 1/3 produced no statistically significant difference 1/3 created a statistically significant negative change
9. How can we make sure to get the best gifts?
10. Empathy
11. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. 1st principle behind the Agile Manifesto
12. Feedback
13. DEV CUSTOMER ! $
14. DEV BIZ CUSTOMER $ OPS !
15. DEV BIZ CUSTOMER OPS ? ? ? Feedback Features = $ != $ Steps to production aka "the customer" aka "the delivery pipeline"
16. DevOps
17. Classic Definition of DevOps - Part 1 Developers Operators
18. Classic Definition of DevOps - Part 2 Development Operations
19. Classic Definition of DevOps - Part 2 Development Operations
20. DevSecNetQAGovOps Classic Definition of DevOps - Part 3 https://vimeo.com/165731278
21. If you mix Sugar, Flour, Cocoa, Salt, Baking Soda and a few other things together, you don’t get SugFloCocSalBak, you get a cake. – Ken Mugrage Classic Definition of DevOps - Part 3 http://www.kenmugrage.com/post/my-new-definition-of-devops/
22. DevOps helps to get user feedback faster https://www.thoughtworks.com/insights/blog/agile-and-user-centered-design
23. How to start Crafting the perfect gift
24. Quiz: Estimate How long does a deployment usually take? minutes / hours / days? How often do you deploy? Daily / weekly / monthly / yearly?
25. Create a Value Stream Map Understand your process
26. Production
27. Each delivery step in the project is a step on the value stream map How to start drawing a Value Stream Map (VSM)
28. Highlight "non-value creation time" and "value creation time" A Value Stream Map - Note down the duration of each step Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD 5min 15min 2min 15min 2min 15min 2w 5min 15min
29. PROD SIT DEV Once you see the full path to production you can identify groups of steps (= phases) A Value Stream Map - Group the phases to get 'stages' Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD 5min 15min 2min 15min 2min 15min 2w 5min 15min
30. Time wasted on waiting for ticket approval. Clicking the approval takes very little time. A Value Stream Map - Detect "waste" Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD 5min 15min 2min 15min 2min 15min 2w 5min 15min 10min
31. How many times do you have to repeat the steps due to feedback? = delivery time to SIT x 4 A Value Stream Map - Detect "Redo" and "unplanned" work Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD 5min 15min 2min 15min 2min 15min 2w 5min 15min 10min avg. 2 times "re-do" avg. 2 times "re-do"
32. How many teams and regulations are involved in the process? A Value Stream Map - Get to know the other people involved Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD 5min 15min 2min 15min 2min 15min 2w 5min 15min 10min
33. How long does it take to change one single line of code in production? Famous question from the Continuous Delivery Book
34. DEV BIZ CUSTOMER OPS Feedback Features
35. Continuous Integration …highest priority is to satisfy the customer…
36. Continuous Integration Code Code Code mainline
37. Quiz / Show hands: How do you get fast feedback? A. Check if it works manually B. Write tests C. Wait for QA to open a ticket
38. Continuous Integration = Fast feedback Check all software changes continuously Continuously = runs on every commit Does the software still work?
39. Continuous Integration - Examples Fail build when script has syntax errors Fail build when code is invalid Fail build when content is invalid Fail build when expectations are not satisfied
40. https://wiki.jenkins-ci.org/display/JENKINS/Monitoring+Jenkins Continuous Integration - Build-Radiators BUILD FAILED BUILD IN PROGRESS BUILD OK

42. Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand. – The Retrospective Prime Directive
43. better communication between developers & teams real time information on process and project status Feedback reduces risk Continuous Integration = Fast feedback = Less Risk
44. Continuous Integration - Fast feedback Build-Radiators: - Show cctray (http://ccmenu.org/) - Show build status monitor (https://nevergreen.io/) - Chatbot (Slack, Hipchat, IRC…) - Show notifications (email notifications are not recommended) Good overview: https://wiki.jenkins-ci.org/display/JENKINS/Monitoring+Jenkins
45. You can't get to continuous delivery if you can't do continuous integration right: 1) commit more often 2) automate, automate, automate 3) trunk based development Tips for efficient Continuous Integration https://twitter.com/scottnasello/status/857307874812321792
46. multiple branches: Continuous Isolation single branch: Continuous Integration Continuous Integration & Branches https://twitter.com/RealGeneKim/status/857306252770201601
47. Continuous Integration Code Code Code feature toggle in mainline feature branch
48. Continuously integrating distributes code ownership. Not "my precious" branch anymore. It's "our" code and failure. – @pm_suzie (Head of Product for @tw_studios @thoughtworks)
49. Continuous Integration Code Code Code feature toggle in mainline feature branch
50. …continuous delivery of valuable software… Continuous Delivery
51. Let's convert the VSM into a Delivery Pipeline! You know now how a Value Stream Map looks like Build Test Deploy DEV Test DEV Deploy SIT Test SIT Wait for Approval Deploy PROD Test PROD
52. Continuous Delivery: What is a pipeline? How most people think software gets delivered https://www.gocd.io/2017/03/01/importance-and-principles-of-cd-pipelines/
53. Continuous Delivery: Pipeline Example https://www.thoughtworks.com/insights/blog/architecting-continuous-delivery

56. Pipelines: Fast feedback https://www.thoughtworks.com/insights/blog/architecting-continuous-delivery
57. Create Pipeline in GoCD Exercise how to build a pipeline based on the notes
58. Why GoCD? GoCD allows you to model your delivery pipeline(s) Easy to convert the Value Stream Map into a working Delivery Pipeline Core concepts of VSM & Pipelines built in by default Easy chaining of tasks Open Source and enterprise support GoCD or Jenkins? https://www.gocd.io/2017/04/25/gocd-over-jenkins/ https://www.gocd.io/getting-started/part-1/
