Lean Engineering: How to make Engineering a full Lean UX partner

In 1999, PayPal's name was synonymous with innovation. In fact, the so called PayPal Mafia (original founders) went on to establish Tesla, SpaceX, YouTube, Skype and other startups. They also provided the early investments of many of the most innovative companies on the internet today. But over time that innovation slowed to a crawl.

In 2011 a number of things begin to come together for PayPal that started its journey back to innovation. This is the story of that reboot and how engineering has played a key role in partnering directly with product and design to move from a culture of products having a long shelf life, to one of rapid experimentation.

In this talk, Bill will outline the principles of Lean Engineering; principles for engineering that enable learning. Drawing from his experience leading User Interface Engineering at both Netflix & PayPal, Bill will walk you through the key principles your engineering team will need to adopt to be that enabler for product and design in your organization. This talk will not just inspire you, but it will also give you some hard earned advice on making this a reality in your organization.

Lean Engineering: How to make Engineering a full Lean UX partner

  1. @billwscott VP Engineering Retail | Merchant | Payments ! PayPal Web Directions South 30 Oct 2014 lean engineering how to make engineering a full lean UX partner
  2. netflix view of customer continuous customer feedback (GOOB) customer metrics drive everything think it. build it. ship it. tweak it fail fast. learn fast. lots of experimentation... build/measure/learn designing & engineering for experimentation
  3. 2011 paypal vs netflix contrast this with a large enterprise like paypal in
  4. In 2011, even a simple content copy change could take as much as 4-6 weeks to get live to site
  5. paypal way of engineering & design (in 2011) roll your own. disconnected delivery experience. culture of long shelf life. inward focus. risk averse.
  6. change is hard
  7. organizations contain anti-bodies that resist change
  8. behavior is deep seated and reinforced
  9. new dna inserted jan 2012 fleshed out ui layer that could support rapid experimentation. march 2012 david Marcus became president of PayPal. set a new charter for innovation. april 2012 formed lean ux team to reinvent checkout experience.
  10. reinvent checkout project lean ux/engineering in action
  11. reinvent checkout project lean ux/engineering in action from whiteboard to code
  12. reinvent checkout project lean ux/engineering in action from whiteboard to code from code to usability
  13. reinvent checkout project lean ux/engineering in action from whiteboard to code from code to usability learnings
  14. reinvent checkout project lean ux/engineering in action from whiteboard to code from code to usability start again learnings
  15. before
  16. after
  17. change has started working its way out
  18. LEAN ENGINEERING enabling build/measure/learn
  19. LEAN ENGINEERING enabling build/measure/learn four principles
  20. 1. enable learning
  21. most organizations biggest challenge is moving from a culture of delivery to a culture of learning
  22. enable continuous delivery engineering has to make delivery a non-event otherwise: delivery dates drive the experience feature-itus becomes prevalent BDUF & waterfall prevail little to no learning
  23. a tale of two trains departs infrequently “gotta get my features on this train or I will have to wait a long time” departs all the time “if I miss this train another one comes in a few minutes”
  24. enable prototyping in the engineering stack because engineering teams are not trying to solve the learning problem, they see prototyping as outside the engineering discipline ! this is a real engineering challenge engineer for the “living spec”
  25. enable prototyping in the engineering stack because engineering teams are not trying to solve the learning problem, they see prototyping as outside the engineering discipline ! this is a real engineering challenge engineer for the “living spec” make prototyping a first class member of tech stack
  26. stack circa 2011/early 2012 simple change could take minutes to see follows an “enterprise application” model. ui gets built into the “app” restricted capabilities* server side components** jsp*** java prototyping was hard “ui bits” could only live here * assumed client developers were low-skill * required server side java eng for simple client changes ** java server pages. server-side java templating solution client server
  27. we blended prototype & production we enabled the “ui bits” to be portable between the prototyping {dust} JS template {dust} JS template node.js java (rhino js eng) stack and the production stack prototype stack production stack either stack
  28. new single stack: prototype & production {dust} JS template java (rhino js eng) production stack {dust} JS template node.js prototype stack the final step is we made the prototype stack and production stack the same technology throughout the application stack
  29. new single stack: prototype & production {dust} JS template node.js java (rhino eng) prototype stack production stack the final step is we made the prototype stack and production stack the same technology throughout the application stack
  30. 2. design for experimentation
  31. the netflix way 16 different test cells in the initial PS3 Launch (2010) focus is on experimentation !
  32. the netflix way 16 different test cells in the initial PS3 Launch (2010) focus is on experimentation ! four distinct PS3 experiences launched on same day
  33. the epiphany
  34. you have to engineer for volatility change is the norm experimentation is not a one time event launching a product is giving birth to the product. the product’s life just begins. ! design for throwaway-ability majority of the experience code written was thrown away in a year
  35. you have to engineer for volatility change is the norm experimentation is not a one time event launching a product is giving birth to the product. the product’s life just begins. ! design for throwaway-ability majority of the experience code written was thrown away in a year the ui layer is the experimentation layer
  36. html5 enabled netflix’s experimentation model netflix gambled on html5 for mobile (iOS, android) and for game consoles, bluray players, hdtvs, etc. why? build/measure/learn. network delivery. new users will see your html5 experience the onramp to onboarding is the lowly link network delivery makes a/b testing straightforward
  37. experiences must adapt All buildings are predictions. All predictions are wrong. There's no escape from this grim syllogism, but it can be softened. Stewart Brand Our software is always tearing itself apart (or should be) Recognize that different layers change at different velocities
  38. enable lots of little bets the big bet. ramping model results in one experience (with some tweaks along the way) after a long ramp up time vs lots of little bets. experimentation model results in many experiences being tested all along the way
  39. 3. democratize innovation
  40. two pizza team?
  41. two pizza team?
  42. keep teams small
  43. democratize the code base starting to use git repo model for continuous deployment marketing pages product pages content updates & triggers into i18n, l10n, adaptation components works well with cloud deployment (devops model) enables the train to be leaving all the time
  44. work in open source model internal github revolutionizing our internal development rapidly replacing centralized platform teams innovation democratized every developer encouraged to experiment and generate repos to share as well as to fork/pull request
  45. use open source religiously nconf q async supertest
  46. 4. give agile a brain credit: Krystal Higgins http://bit.ly/18uP7N1
  47. agile is just a machine it will crank ‘stuff’ out it can be good or bad stuff please don’t waste the machine have a tight loop with our users iterate to get experience “in the ballpark” make it easy to iterate designs ahead of agile sprints
  48. agile is just a machine it will crank ‘stuff’ out it can be good or bad stuff please don’t waste the machine have a tight loop with our users iterate to get experience “in the ballpark” make it easy to iterate designs ahead of agile sprints the “brain” is our user

  51. how teams get the right mindset shared understanding deep collaboration continuous feedback
  52. the mind of the team does your team “defend the solution” or “embrace the problem”?
  53. rethink engineering in the light of lean 1. enable learning 2. design for experimentation 3. democratize engineering 4. give agile a brain LEAN ENGINEERING ! ! Engineering for build/measure/learn
