It is important to guard against overconfidence or diffidence regarding the use of computers by understanding what computers can and cannon do. Also, the leaders of enterprises should remember that the information from scholars or workers used I computer programs can often be biased. The second issue concerns management in system development. while the creation of software is the work of an individual, system development as a whole requires cooperation. Therefore, when giving advice individuals, managers should select a setting where the members can easily communicate with each other, to achieve and maintain working partnerships. The third issue concerns the future of the computer industry, which experienced a change due to the appearance of the personal computer, and is now due to meet further changes as a result of the communications revolution. After the appearance of the personal computer, the market changed from selling hardware to emphasizing software. Network systems using personal computer as terminals, are spreading. This will continue to advance toward more unified systems when the interchangeability of operating systems increase and new communication systems are developed.
