“That’s how we’ve always done it.”

"The other “commandment” is to become very suspicious anytime you ask, “Why do we do this like that?” and you receive the answer, “That’s how we’ve always done it.” If no one in the organization can explain why a certain practice is the best, or why the product has to offer certain features, that may reveal a bad habit. I suggest several activities the leaders of organizations can do to get to the bottom of this puzzle. First, write down key business processes and ask yourself if you understand why the organization is doing it this way. Then ask others in the company if they understand why. Finally, ask newcomers to the company — after they have been with the organization two or three months — what processes they have seen in the organization they do not understand.

When processes become routinized, silos develop across firms, communication and cooperation fade away, and certain departments begin to command a disproportionate amount of resources. If the company waits for these things to emerge, it is often too late and too difficult to change. Instead, the company should adopt minor but proactive changes on a consistent basis."
