ADDC 2017 - Richard Erwin: Streamline your app design and development for faster release cycles

Mobile app projects are becoming increasingly complex, while users have high expectations and low tolerance for apps which fail to meet them. Simplify mobile development process and automate your app delivery pipeline, freeing you to focus on building new features, releasing faster, and exceeding customer expectations and business demand. With Mobile DevOps:

- Ensure that your apps look, feel, and perform well for any user, across a diverse platform and device landscape
- Increase efficiency and be cost effective by automating processes like app testing on multiple devices
- Stay ahead of the competition and react quickly to market demands and changes
- Keep your users continuously engaged by responding to user feedback and solving performance issues and app crashes
- Free up time to focus on what matters: innovating and delivering value to users.

This session will look at how to embrace an integrated Mobile DevOps approach to enable you to build great apps, have fast release cycles, and focus on what users really want.

13. Benefits of DevOps
14. Mobile Quality Challenges • Device fragmentation • App complexity • Fast release cycles • Short sessions • High mobile user expectations
15. Benefits of DevOps • Increase quality and reduce technical debt • Improve communication between functions • Accelerate your Design, Development & Release cycles (Cycle Time) • Decrease deployment failures • Increase time to innovate • Improve Agility
16. Manage Technical Debt 0 1 2 3 4 5 Technical Debt Sprint 1 Sprint 2 Sprint 3 Sprint 4 Sprint 5 Debt > Sprint Debt accumulation

The true cost of a software bug Source: National Institute of Standards & Technology The average cost if found in the Gathering Requirements phase 1X The average cost if found in the Coding/ Unit Test phase 5X The average cost if found during Beta Test Programs 15X The average cost if found in Production 30X X is a normalized unit of cost and can be expressed in terms of person-hours, dollars, etc.

26. Lifecycle of a Mobile App
27. Plan & Design 1 Monitor & Learn Release Develop + Test 2 Development Production 4 3 Visualise your process (Value Stream Mapping)
28. It starts with an idea – and a plan how to turn this idea into reality … Develop + Test 1 Plan & Design Project starts Design Wireframe Discovery Concept Architecture Manage Work & Track progress
29. Write Code Unit Testing 2 Build Version Control Build Verification/ Auomated Testing Release Once the iteration starts, developers turn great ideas into features … Develop + Test
30. QA & Stakeholders Automated testing environment 3 Beta Users Store Release Monitor + Learn When all tests pass, the build is deployed to testing environments for each stage in the release process Release
31. Learn and understand how users use your app, how it reacts and quickly fix issues and bugs Monitor + Learn 4 Monitor Feedback Plan the next iteration
32. Demo Visual Studio Mobile Center Commit - Build - Test - Distribute
33. Summary
34. Summary • Visualise your end-to-end process • Limit Work In Progress • Focus on quality • Use Validated Learning to drive project • Automate where possible • Continuously Improve (Kaizen) Distribution Monitoring Engagement Repository Build Automated Testing Design/Code
