My name is Karl Scotland and I help businesses become Learning Organisations.

Over the last 15 years I have been an advocate of Lean and Agile approaches to achieve this, working with companies including the BBC, Yahoo!, EMC Consulting and Rally Software. During this time, I have been a pioneer of using Kanban Systems for software development, a founding member of both the Lean Systems Society and Limited WIP Society, as well as being active in the community and a regular conference speaker. As a result I was awarded the honorary Brickell Key Community Contribution Award at the 2013 Lean Kanban North America conference.
