A healthy agile project has several typical rhythms such as releases, iterations, stand-up meetings, builds kicked off by continuous integration, and the red-green-red test cycle of a developer. These rhythms have healthy ranges (such as a stand up meeting lasting less than 15 minutes) and characteristics (such as that same stand up meeting not containing design discussions). When they fall out of these ranges or do not display the appropriate characteristics, they indicate that something is wrong with the agile process.
