6. Business architecture is a concept explored in detail in Moore’s Dealing with Darwin. “Organizational structure based on prioritizing one of two business models (Complex systems model and Volume operations model). Innovation types are understood and executed in completely different ways depending on which model an enterprise adopts.” For more, see http://www.dealingwithdarwin.com/theBook/darwinDictionary.php

2. If you’re having trouble accepting this fact, it really is helpful to watch it on video. One extremely detail-oriented blogger took one video and broke it down, second-by-second, to see where the time went: “You lose between 2 and 5 seconds every time you move the pile around between steps. Also, you have to manage the pile several times during a task, something you don’t have to do nearly as much with [single-piece flow]. This also has a factory corollary: storing, moving, retrieving, and looking for work in progress inventory.” See the rest of the commentary here: http://lssacademy.com/2008/03/24/a-response-to-the-video-skeptics/
3. Timothy Fitz, an early IMVU engineer, deserves credit for having coined the term continuous deployment in a blog post: http://timothyfitz.wordpress.com/2009/02/10/continuous-deployment-at-imvu-doing-the-impossible-fifty-times-a-day/. The actual development of the continuous deployment system is the work of too many different engineers at IMVU for me to give adequate credit here. For details on how to get started with continuous deployment, see http://radar.oreilly.com/2009/03/continuous-deployment-5-eas.html
