Everything about Lean, Agile and Six Sigma in one place!
Lean starts from the customer: who is the customer, what does the customer want and what is the customer willing to pay for? Then it is about (added) customer value, flow, pull and continuous improvement.
Agile is a way of working where agility is paramount. An organization that implements a project using the Agile methodology is aware that circumstances are changing, and knows how to respond accordingly.
Six Sigma is a method to increase the efficiency and effectiveness of a process, in other words, doing the right things and doing the right things.
