Computer softwareAs more and more companies are using the Internet to do business, Mark Williams explains how a new software package is helping the efficient transfer of medicines from factory to patient.AHL Pharmaceuticals is one of Britain’s largest wholesale distributors of medicines. Under a European parent company, Setra AG, it covers 40 per cent of the British market. The company buys medicines from the manufacturers and delivers them on a twice-daily basis to hundreds of hospitals and pharmacies around the country.’The responsibility for supplying such large quantities of medicines is frightening,’ says IT director, Stephen Smith. ’If a manufacturer has quality control problems, creating a shortfall in supply, or if medicines are suddenly needed in large quantities somewhere else in the world our stock levels can fall dramatically. In the past such a lack of balance between supply and demand was a huge problem. With our new software system, we know immediately of any possible manufacturing or supply difficulties, can warn our customers and suggest possible alternatives.’This system is so efficient because manufacturers can update details themselves of stock levels and product information. Twice a day staff at AHL transfer this data to their main computer system where it is made available through the AHL website to company personnel and customers.With so many people having access to the data, isn’t the security of the system at risk ’Not at all,’ says Smith. ’We run the software within our own internal security system. The data goes into a special "sandbox" which is separate from the rest of the system. Even if someone manages to get into the software, they can’t go anywhere else on the network.’And does he think that this is the limit of the software’s use ’The first time I saw this I had the feeling that life would be different from now on. Instead of having lots of pieces of paper flying around, an expansion of the software system into the purchasing department means that orders can now be dealt with in a moment. The only delay to further expansion is deciding what area of the company to apply it to next.’ The new software（）

The jewellery designerHe was young and completely unknown, but Paul Waterhouse believed in himself. He’d heard that there was going to be a large exhibition for jewellery designers and he asked the organisers whether he could show some of his work. ’I was only 21,’ he says, ’and they agreed, if I could show a complete collection.’ So he went to the bank, borrowed ￡1,500 for materials, and began to work on new designs. ’The exhibition was fantastic. Although everyone else was much more experienced than I was, my designs were still praised.’He decided to transfer his business to Canada and began to experiment with new materials: all sorts of stones from around the world, some totally new to him. ’As most of them weren’t precious, it changed the way I approached design. It was great! I was able to produce much larger pieces of modern jewellery,’ he says. ’Then I was asked by an advertising agency to design a wedding ring for a TV advert. The agency liked what I’d done, but their client, a car manufacturer, wanted something a little more traditional. I was happy to make changes and that work gave me a lot of free publicity.’ People at the exhibition admired his designs.（）
