* '''Repeatability ''' - Given the same inputs, the B&R process must reliably produce the same outputs every time.* '''Automation ''' - Since portions of the B&R process will be repeated thousands of times through the life of a product, automation is used to ensure consistency, reduce labour, and maximize throughput.* '''Speed/efficiency ''' - To enable fast development, testing, and patching cycles, B&R processes are usually optimized for speed, using a number of strategies including distributed processing - build jobs may be spread across dozens or hundreds of machines.
