Only dead fish go with the flow. As Andy Hunt and Louise Hoffsten remind us, it's vital to constantly question the environment in which we live. Like a salmon, we need to return to our roots if we want to progress again. Do we need to work with a scaled framework? Are we capable of doing so? How can we adapt our vision of the Scrum model and adopt new reflexes? I'd like to tell you how - thanks to the LeSS model - a team of teams managed to make their own way in a major airline company, against all expectations.
