Until the decade of '50, all data processing was based on the delivery of groups of documents (or information) to the so called "computer centers" in order to obtain the output hours or days later. No significant impact was made on management. Nowadays, networking, real time processing, telecommunications, worldwide accesses and user-oriented software, make it possible to store, share and retrieve great amounts of information quickly and safely. These capabilities have made important impacts on management, quality, efficiency and efficacy, and promise to make a lot more in the future.
