My presentation from the first edition of Agile Manchester summarises what we - Culture Work - have learned during two lean transitions that were very different in nature. It shows how different management approaches and cultures influence the introduction of lean management and highlights the importance of balancing push and pull. It explains how to use and combine different lean methods and approaches (e.g. awareness trainings, retrospectives, A3 problem solving, agile project management) for a company-wide roll-out of lean.
