The UK 'Building Down Barriers Handbook of Supply Chain Management-The Essentials' states that: 'The commercial core of supply chain management is setting up long-term relationships based on improving the value of what the supply chain delivers, improving quality and reducing underlying costs through taking out waste and inefficiency. This is the opposite of 'business as usual' in the construction sector, where people do things on project after project in the same old inefficient ways, forcing each other to give up profits and overhead recovery in order to deliver at what seems the market price. What results is a fight over who keeps any of the meagre margins that result from each project, or attempts to recoup 'negative margins' through 'claims', The last thing that receives time or energy in this desperate, project-by-project gladiatorial battle for survival is consideration of how to reduce underlying costs or improve quality'.
Ries and others created an annual technology conference called Startup Lessons Learned which has subsequently changed its name to the Lean Startup Conference.  Lean startup meetups in cities around the world have garnered 20,000 regular participants.  The first lean startup meetup named Lean Startup Circle was created by Rich Collins on June 26, 2009  hosting speaking events, workshops, and roundtable discussions. As of 2012, there are lean startup meetups in over 100 cities and 17 countries as well as an online discussion forum with over 5500 members.  Third-party organizers have led lean startup meetups in San Francisco , Chicago , Boston , Austin , Beijing , Dublin , and Rio de Janeiro , among others—many of which are personally attended by Ries—with the Chicago and New York City Lean Startup Meetups attracting over 4,000 members each.  The Lean Startup Machine created a new spin on the lean startup meetups by having attendees start a new company in three days.  As of 2012, the Lean Startup Machine claimed to have created over 600 new startups this way.
