Enabling Lean with Tech: lessons learned applying lean at paypal

  • 1. enabling lean with tech lessons learned applying lean at paypal bill scott (@billwscott) sr. director, user interface engineering, paypal Lean Startup in the Enterprise. The Lean Startup Conference with Jeff Gothelf. Dec. 4, 2012. San Francisco, CA
  • 2. at Netflix 90% or more of the “ui bits” were thrown away every year. doesn’t take too many tests to result in lots of throw away code. followed buid/test/learn designed for volatility
  • 3. new dna @paypal march 2012 david Marcus becomes president of PayPal april 2012 we form lean startup team to reinvent checkout experience
  • 4. in the midst of transformation
  • 5. tangled up technology big problem. technology and processes not geared to build/test/learn.
  • 6. a tale of two stacks non- long non- release standard UI standard UI cycles two non-standard xml jsp stacks c++ java new stack tied to Java “one word” change old new could take 6 weeks to fix
  • 7. leave the old behind X non- non- standard UI standard UI we can rule out the old xml jsp stack c++ java old new
  • 8. need to design for volatility prototyping non- standard UI is hard but still the new stack is “ui bits” jsp not conducive to could only prototyping live here java follows an “enterprise application” model. ui gets built into the “app”
  • 9. 1. set the ui bits free
  • 10. separate the ui bits templates = JS code = JS style = CSS images engineered the user interface stack so that the only artifacts are: • javascript • css • images
  • 11. separate the ui bits templates = JS code = JS style = CSS images templates get converted to javascript <p>Hello {name}</p> JavaScript we use dust.js
  • 12. separate the ui bits templates = JS code = JS style = CSS images language independent server/client agnostic CDN ready cacheable rapid to create
  • 13. make the ui bits portable open source open source JS template JS template open source JS templating can be JS template run in client browser or server on the production node.js java stack we can drag & drop the prototype production ui bits from prototyping stack stack stack to the production stack
  • 14. free to work together co-located lean ux team whiteboard to code code to usability product/design user interface usability/customers team engineers
  • 15. free to work together co-located lean ux team whiteboard to code code to usability product/design user interface usability/customers team engineers templates = JS code = JS style = CSS images node.js
  • 16. free to turn sketch to code forcing function. it brings about a close collaboration between engineering and design it creates a bridge for shared understanding requires a lot of confidence and transparency
  • 17. free to test frequently with users
  • 18. free to iterate independent of agile usability usability usability usability usabili lean ux - lean team track { user interface engineering - agile scrum team agile sprint 0 engineering - agile scrum team release release release release
  • 19. 2. embrace open source
  • 20. use open source religiously
  • 21. work in open source model internal github revolutionized our internal development rapidly replaced centralized platform teams innovation democratized every developer encouraged to experiment and generate repos to share as well as to fork/pull request
  • 22. give back to open source we have a string of projects that will be open sourced node bootstrap (similar to yeoman) contributions to bootstrap (for accessibility) contributions to bootstrap (for internationalization) component repository framework for github (similar to bower) and more...
  • 23. 1. set the ui bits free 2. embrace open source
