34. Controlled Chaos
Scrum emphasizes on project management
De-emphasis command-and-control management approach
There is a strong emphasis on monitoring (features delivered) and
adjusting according to the results
The aim is to find a balance between allowing the business to change
their mind and the development team to be able to get work done on a
stable scope

35. Scrum Values
Commitment. Be willing to commit to a goal. Scrum provides
people all the authority they need to meet their commitments
Focus. Do your job. Focus all of your efforts and skills on doing the
work that you have committed to doing. Don’t worry about anything
else
Openness. Scrum keeps everything about a project visible to
everyone
Respect. Individuals are shaped by their background and their
experience. It is important to respect the different people who
comprise a team.
Courage. Have the courage to commit, to act, to be open and to
expect respect
