This document discusses making a paradigm shift towards effective Scrum practices. It suggests that the most visible but least powerful aspects of Scrum are tools and processes, while the least visible but most powerful aspects are the underlying theory, principles and values. Common diagnoses for why Scrum may not appear to work include using the process incorrectly, blaming others, impatience, not adapting the process, or using the wrong process altogether. The document provides suggestions for addressing each diagnosis, such as using the process correctly, fixing actual problems rather than blaming the process, maintaining progress over time, and considering alternative processes if Scrum does not suit a particular situation.
