Sam Walton is regarded as one of the greatest project entrepreneurs in the retail chain industry. He had a great passion for learning. He frequently made unannounced visits to Walmarts around the country to learn what local innovations were working that then could be shared with other Walmarts. On one of those visits he was puzzled by a greeter saying “hello” at the entrance of the store and asked the fellow what he was doing. The greeter explained that his main job was to discourage shoplifters from taking unpaid merchandise out of the store through the entrance. Walton was delighted and shared the innovation with “associates” throughout his chain.
