Provide an example of technical obsolescence, and explain how it can be a threat to an information system.
What will be an ideal response?
Typical examples of technical obsolescence are:
• Operational costs or execution times are increasing rapidly, and routine perfective maintenance does not reverse or slow the trend.
• A software package is available that provides the same or additional services faster, better, and less expensively than the current system.
• New technology offers a way to perform the same or additional functions more efficiently.
• Maintenance changes or additions are difficult and expensive to perform.
• Users request significant new features to support business requirements.
As the chapter points out, constantly changing technology means that every system has a limited economic life span. Analysts and managers can anticipate obsolescence in several ways and it never should come as a complete surprise. A system becomes obsolete when it no longer supports user needs, or when the hardware or software platform becomes outmoded.
