Shifting from waterfall into a flow based delivery mechanism is an exercise in change management and change management is as much about the people as it is about the new process or tool. In fact, it could be argued that until the people align their beliefs and thinking to the new processes, the impact of the change will be minimal. Which brings me to the issue of language and words.
Words are how we communicate what we are thinking, what we need and want and what needs to get done. Language also creates ‘position’ in a team.
