Lean Architecture goes beyond the usual hog wash about what is the right thing to do in an agile project. It recognizes the need to deliver fast and often, to save money and to free development teams form architectural burdens imposed upon them. Yet it realizes that  a focused vision and careful analysis are key to ensure long term flexibility, adaptability and cost effectiveness. Lean architecture forces teams out of short term thinking that will lead them into instant legacy hell, yet it combines the insights of Agile and Lean development with the experience engineering.

This two-day course on Lean Architecture will demonstrate how Lean thinking helps create software design to create flexible and targeted architectures, without the waste and  the unproductive paper pushing accompanied by big design upfront. The Lean Architecture approach allows you to build and grow software incrementatlly over time and to bridge the gap between requirements and architecture. It builds on Tygve Reenskaug's DCI (Data, Context and interaction) approach to make sure the software  builds the end-users mental models and thus make the software much more usable.
