systems. Because of the need for new applications to share data in a common format with existing systems, inheriting the six-digit date field that has become a standard over time. The disaster scenario envisaged is that a great number of computer systems around the world will make processing errors and will either crash or produce incorrect outputs . As a result financial institutions, businesses organisations, informational technology and even aeroplane radar communications will all then be in a welter of confusion. In military services, the system meltdown may also worsen the appropriate control of nuclear missiles in silos. It is a ticking time bomb destined to wreak havoc on millions of computer systems in every economy, both commercial and residential, and thus need everyone's serious attention. However, the bug is likely to affect more staggeringly the business computers which imply an alarming economic problem. Many organisations have not yet started projects to examine the impact of the millennium bug on their systems. By applying The Standish Groups CHAOS research to Year 2000 projects, 73% of Y2K projects will fail according to the pace now taking. The biggest challenge for these companies is convincing top level management of the severity of the year 2000 problem and the amount of time, money and resources needed to fix it. On that account, to ensure this disaster is minimised, none of us should worm out of devoting resources in preventing the potential anarchy. It is a costly Task As simple as the problem sounds, the fix for the Millennium Bug will cost up to US$600 billion world-wide, according to estimates by the Gartner Group, a leading information technology consultancy. The software fixes are very time-consuming, requiring considerable effort to examine millions of lines of source code in order to locate problem date fields and correct them. The costs to apply the fixes will vary from company to company, but research h...
