overhead that is what training is usually charged to.Selection Criteria The Information Technology had a list of selection criteria upon which was based the decision to move to Windows NT platform. The following criteria were used to make the choice between UNIX and Windows:a) Application availabilityb) Costsc) Support and Maintenanced) Ease of Usee) Interoperability/Compatibilityf) PortabilityBy year 2002, the architecture, engineering and construction (AEC) expect over 95 percent of desktop applications to be Windows-based.The initial costs involved with migrating to Windows NT will be lower than those related to use of UNIX. Compatibility of the chosen operating system with existing system is crucial. Although the company expects to eventual stop using UNIX, at the present time that is not feasible. Therefore, the chosen operating system has to be able to handle applications, data, etc. created in other formats (platforms)."It is hard to discuss Interoperability computing without talking about co-existence with UNIX. The high degree of interoperability of the Microsoft Windows NT server operation system allows existing systems to run undisturbed as the new capabilities offered by the Windows NT family of network and workstation products are rolled into the enterprise computing environment. Because UNIX interoperability is such a huge issue in the potential Windows NT marketplace, Microsoft has developed a wide variety of specific technologies, support tools, and solution providers who are in the business of making this transition successful." [John's]This is an important selection criterion because ease of use will help make the transition be a lot less cumbersome. UNIX is a command-based system that requires users to remember commands. Windows has a user-friendly graphical interface based on icons.NT vs. UNIX? Although the Team had decided to maintain some of its UNIX applications, the decision of which operating system - Wi...
