An information system can be defined as a set of a coordinated network of components. which act together towards producing, distributing and or processing information. An important characteristic of computer-based information systems information is precision, which may not apply to other types. So, the purpose of an information system is to turn raw data into useful information that can be used for decision making in an organization.
Direct conversion strategies of Information System
The following describes a brief summary of the direct conversion method in the context of the Spice Hotel database solution –
Direct conversion is an implementation process that involves essentially “switching off’ the current system entirely and “switching on” the new system to take its place all at once. The old system is no longer available for use from that point onward.
In the context of the database solution for Spice Hotel, this would mean shelving the old paper-based entry and lookup system entirely and have all users and participants use the new electronic database solution the next business day.
The recommendation would be not to employ this method of conversion, as the current and new systems are vastly distinct from each other. The greatest risk is the learning curve required by users and participants to interact effectively with the new system. Other major risks include the new system not performing as per the requirement report specifications, which will impact the business in a profoundly negative manner as the old system will no longer be available as a redundant failover. The risks to the business of direct conversion far outweigh the financial benefit from simply switching off the current system and immediately replacing it with the new solution.
