I'd expect a CMM audit to ask if you have a standard and how you enforce it. You could probably get by with any reasonable standard. A standard configuration for the code formatter in your IDE will help developers comply. I exported my config from Eclipse and asked all developers to import it. Most did. Static code analyzers like Hammurapi will give compliance statistics.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
