Agile software development has proven to be more successful than traditional methods. However there are many Agile methodologies (Scrum, Kanban, Lean, XP). It is difficult to make a right choice. Do you want to know the differences between Scrum and Lean? Perhaps you struggle with your existing Scrum implementation and looking for a better methodology. So did I. I spent many hours looking for continuous improvement beyond Retrospectives and Sprint Reviews. And I found my answer in applying Lean Principles. This session will help you to increase your understanding of Lean and Scrum. It will also give you some practical examples of implementing Lean in Scrum teams.
