This document discusses behavioral aspects that can challenge the successful implementation of agile practices like Scrum. It begins by outlining values from the Agile Manifesto that emphasize individuals, collaboration, responding to change, and working products over processes, tools, contracts and documentation. The document then discusses Scrum values and some specific behavioral challenges like forcing Scrum Master or Product Owner roles, a lack of servant leadership, lack of discipline, thinking testing is not the developers' responsibility, people not speaking up, lack of attention to detail, lack of planning, and saying yes when meaning no. It provides examples and images to illustrate these challenges.
