SCRUM Values
The SCRUM values are derived from the Agile values of software development.
Individuals and interactions over processes and tools - processes and tools are helpful, but they will do you no good if the team does not communicate and collaborate in a constructive fashion.
Working software over comprehensive documentation - documentation is important, but what's most important is to have working software.
Customer collaboration over contract negotiation - you are not just looking to get a contract and get money that way - you are solving the customer's problem.
Responding to change over following a plan - if the requirements or perceived requirements changed, so should the plans and design.
