The equipment is broken, or doesn t work right, or doesn t meet user needs. A vendor didn t do the work, or sent a wrong invoice, or didn t send a promised credit. And on and on like that. Suppliers convince you their new products and services are better than what you have now. You rely on the industry to direct you.
Senior managers mandate a change.
You rely on internal resources to direct you. Complaints from customers internal or external force through a change. Now I don t question that impuses of this sort are useful. But they cannot substitute for your own initiatives. You are in the best position to identify what needs to change before problems become acute.
