Lean is a mindset that challenges us to look for ways to deliver value to our guest at faster speeds, with lower cost and better quality. Lean thinking changes the focus of management from optimizing separate technologies, assets, and vertical departments to optimizing the flow of products and services through entire value streams that flow horizontally across technologies, assets, and departments to customers. All activities that do not add value are considered waste.
Agile originated with the Agile Manifesto, a document that outlines the values and principles of Agile Software Development. While Agile has it's roots in Software Development, Target has started applying the same values and principals to non-software work.
