The potential of EDI is virtually unlimited, but the success of any EDI initiative hinges on its ability to directly support strategies that achieve your institution's business objectives. At its most fundamental level, EDI technology automates current business practices, speeding up the exchange of business information. This application of EDI most often is found in a hospital's material management department. But EDI integrated internally within a hospital and externally with suppliers and vendors has the potential to go beyond simple automation and to transform processes. This is where the full value of EDI can be realized. No matter which level of EDI participation hospital management decides is appropriate to fulfill its business objectives and strategies, EDI will affect the entire institution's exchange of information with its internal and external audiences. The question management must answer is: Will the hospital's EDI strategy be offensive and managed, or defensive and reactive? Today's environment leaves no room for a "no-strategy" EDI option. The options are either to proactively shape EDI, or reactively play catch-up. EDI can work for you. Adequately developing an EDI game plan in support of your business objectives and calling on your suppliers and other trading partners to work with you will ensure EDI is an asset to your facility.  相似文献

Characteristics of communal club members who use input packages are studied using a survey of communal clubs serviced by Africa Co‐operative Action Trust (Acat) in KwaZulu during 1989. Discriminant analysis shows that full input package adopters tend to belong to older clubs, have less formal savings and receive more visits each year from KwaZulu Department of Agriculture (KDA) extension officers. They also have a greater proportion of land under sugar‐cane, larger farm sizes and a higher rand monetary value of livestock.

Members of older clubs benefit from greater club experience in ordering inputs and liquidity for securing discounts on bulk orders. Clubs also enable scarce KDA extension manpower resources to be used more effectively by focusing extension efforts on groups rather than individual farmers. Sugar‐cane production probably indicates member willingness to innovate and the availability of funds to buy complete input packages for other crops. Increased access to land promotes input package adoption which can raise agricultural productivity. Development of institutional arrangements for a land rental market in KwaZulu should be considered. Higher monetary values of livestock reflect Increased ability to bear risk associated with technology adoption and that adopters have the means to purchase input packages  相似文献
