Scrum

Licensed Under Creative Commons by Naresh Jain
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

Scrum ValuesCommitment. 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
