Identical programs on all computers make it very easy for users to use the programs on several different systems. The same manuals are given to customers with the PC version of NISA as with the Cray version of the programs. These groups were located in the U.S.A., Japan, Europe, Korea, and now in India and worked with many of the pioneering companies in the fields of finite element analysis, CAD, CAE, etc. Thus, the NISA family of programs was developed with an eye to making them very easy to use. Before being released to customers, all the NISA programs are very well tested.
Quality assurance is thus very well done.
