Under what circumstances might an organization decide to scrap a system when the system assessment suggests that it is of high quality and high business value?
What will be an ideal response?
Examples of where software might be scrapped and rewritten are:
1. When the cost of maintenance is high and the organisation has decided to
invest in new hardware. This will involve significant conversion costs
anyway so the opportunity might be taken to rewrite the software.
2. When a business process is changed and new software is required to support
the process.
3. When support for the tools and language used to develop the software is
unavailable. This is a particular problem with early 4GLs where, in many
cases, the vendors are no longer in business.
There are other reasons why software may be scrapped, depending on local
cirumstances.
