Seeing things through the lens of art AND science helps a team embrace the objective AND subjective aspects of their tasks and problem-solving quests. Teams that reject science feel their way through life. They rely on their gut and some form of mysticism to decide the questions of who, what, where, when, why, and how. They miss the efficiency that objective facts, methods, and best practices have to offer. Teams that reject art rely too heavily on what can be known. There are gaps in the amount of data that can possibly be collected and there is a time and place to do the irrational in order to preserve the soul of the team. Great teams know when to apply art AND science and enjoy an existence where the two are tools that are not mutually exclusive.
