1 .With speed increasingly seen as the key to competitive advantage, the dream is to marry the control of an established company with the responsiveness of a start-up. As Linda Applegate reports, advances in IT now means that the “big small”company is finally feasible. In the hierarchical companies of the 1960s and 1970s, informaiton moved slowly and channels of communication were limited. Over the past few years, however, large companies have come under ever-increasing pressure to collect, process and distribute information more quickly in order to compete with smaller, more nimble rivals. The key challenge facing any sizeable organisation today is how to achieve responsiveness without losing the control inherent in a hierarchical structure. All types of organisation are controlled through two sets of processes. Operating processes define how a company produces, sells, distributes and supports its products and services. Management processes define how a company directs, coordinates and controls these operations. Typical management processes include planning, budgeting and human resource management. Traditional hierarchical organisiations control operating processes through standardisations of jobs. These jobs are separated into sequential steps and carried out under direct supervision. However, the line workers lack both the authority and motivation to improve these routine tasks and are limited by their local view of the business. Management processes in such companies are also hampered by the time it takes to recognise that change is needed. Thus, hierarchical control is only truly effective in relatively stable business environments where change happens slowly. Entrepreneurial organisations, on the other hand, allow fast response without any loss of control. Daily personal interaction between the owner and employees ensures flexibility and responsiveness, while instant feedback ensures effective control. However, as the company becomes larger and more complex, this control breaks down and more structured operating and management processes required. Information age organisations can manage the complexity of the large hierarchical structure without losing the speed of the entrepreneurial start-up. IT plays a critical role. It coordinates complex fast-cycle operating processes and, more importantly, gives decision-makers quick access to detailed, real-time information about operations and market performance. Once all the information is flowing, employees can quickly evaluate their decisions and continually refine both strategy and operations. Organisational control then becomes a dynamic, information-enabled learning process rather than a static monitoring system. However, although IT makes the “big small” company possible, it can not motivate people to use information in order to act on behalf of the organisation. The challenge for organisation is therefore to ensure that managers and employees share the same perspective on the business and are motivated to accomplish the same goals。 2. Since agriculture accounts for nearly 70 percent of the world’s fresh water withdrawn from rivers，lakes，and underground aquifers for human use，the greatest potential for conservation lies with increasing irrigation efficiency1.
