Lean Engineering at PayPal: Applying Lean Startup Principles at Enterprise Scale

  • Apr 24, 2013 · 6:30 PM


How do you take a gigantic organization like PayPal that was entrenched in a culture of a "long shelf life" and transform it to a culture of rapid experimentation? Bill Scott, Senior Director of UI Engineering at PayPal, will give 3 principles applied to PayPal engineering to make it a full partner with Lean UX. This will be illustrated by showing how they re-factored the tech stack and changed the way engineers work in Lean streams with design & product partners and how it plays with agile.

As a backdrop Bill will discuss several historical factors in the field of software engineering that are anti-thetical to the Lean Startup mindset but still find their way into most large enterprises. By understanding this historical context and applying lean principles he will demonstrate how a lean transformation can take place in any enterprise.


Bill Scott is the Sr. Director of UI Engineering at PayPal. In a past life he co-created one of the first successful Macintosh games (GATO, 1985), built & designed wargaming interfaces for NATO, led user experience teams (Sabre, Meebo), co-wrote one of the first Ajax/JavaScript frameworks (OpenRico), managed user interface engineering organizations (Netflix, PayPal) and published a design pattern library (Yahoo!).

Bill is also a frequent speaker at conferences & workshops worldwide as well as the co-author of the O’Reilly book Designing Web Interfaces. Follow Bill ’s tweets @billwscott and his ramblings on

    Minimal value for me. Scaterred presentation centred around the presenter and not the topic. It would have be great to focus on the lessons learned, and areas of improvements.

    It was great, I learned a lot although with the wealth of information, this meet-up seemed a little short..

    Lots of good information. Speaker did a good set up in terms of 'dating" the infrastructure and processes he encountered there
