Having a large consulting contract with money to burn can make it easy to succeed but what do you do when you’ve got a small team with limited resources? Taking inspiration from lean software development and lean start-ups I have singled out several principles that help agile teams get more out of less. Examples include Continuous deployment, FDD (Feedback Driven Development), and Kanban. I will explore what each of these are, how I applied them in the Rails stack and reflect on what effect they had on my team’s productivity and application quality.

- 8. Guiding Principles 1. Focus on Value 2. Minimize Effort 3. Deliver Fast
- 9. 1. Focus on Value “First, learn what is core to what you are building then provide just that”
- 10. Add Nothing but Value what is value? understand it should be owned by everyone
- 11. Feedback Driven Development • creating useful software that people value • learning what reaches users • process for validating change • doing so with as little effort
- 13. Customer Development • reducing market risk • what problem are you solving? • who are your customers? • will they pay for it?

- 17. Pivot • tweak features to get better results • if pivoting doesn’t work, remove
- 19. Simplicity • strip features to the essence that achieves value • spiking large features • “Do the simplest thing that could possibly work”
- 20. Simplify Game
- 21. Delay Commitment • pushing off decisions, commitment until the last possible moment • yagni - you ain’t going to need it
- 22. Minimum Viable Product • Rails Rumble/Startup Weekend • starting place for validated learning with the least effort • should be embarrassing • early adopters see the potential
- 23. 3. Deliver Fast
- 24. Kanban • a pull-based system for continuous flow of work • project management tool • expression of just in time • emphasis on flow
- 26. Kanban Benefits • simple, less process • limit work in progress, maximize throughput • easy to change direction • less inventory of requirements/stories • less time in meetings • more easily spot bottlenecks
- 27. Continuous Deployment • automated deployment of completed code to production • ship features when ready
- 28. Commit Monitor Test Deploy
- 29. Details • automated testing with continuous integration • simple deployment/rollback script • ‘stop the line’ on failures • real time alerts in production • five whys - root cause analysis
- 30. Benefits • deliver features/bugs fixes faster • reduce shelf time for finished work • eliminate waste in deployment process • find integration issues quicker and in isolation
- 31. Takeaway • don’t waste resources on stuff that doesn’t matter • pivot as you learn from your users • focus on flow • ship when features are ready
