Good morning. In today's class we'll be comparing two supermarket chains whose futures are looking very different at the moment. First of all, the Williams chain. Sharon Tucker joined Williams two years ago as Sales Director, taking over as Chief Executive three months later. The company was struggling. Sales growth was fading away, and profits were falling. Its strategy of focusing on redesigning stores was doing nothing to boost sales. In short, Williams had lost its way. After just one year under Tucker's leadership, it's regained its confidence, and with good reason. Sales have been rising for 15 months, starting almost as soon as she walked in the door. They're up by five per cent in the last six months, excluding new space, with profits over the same period rising by ten per cent. And the company claims to have attracted a million new customers.
