" One insurance executive I worked with described the major benefit he derived from implementation of this system: “Previously I would just tell everyone, ‘Sure, I’ll do it,’ because I didn’t know how much I really had to do. Now that I’ve got the inventory clear and complete, just to maintain my integrity, I have had to say, ‘No, I can’t do that, I’m sorry.’ The amazing thing is that instead of being upset with my refusal, everyone was impressed with my discipline!
