Martin has been researching software options but cannot decide among three

alternatives. Martin started his search at Computers Made Easy $($CME$)$ and almost

wished he had looked no further. Ricky Bose, the manager of CME, appeared

knowledgeable and listened attentively to Martin's problems, needs, and concerns. Ricky

had software and hardware that would, with a few exceptions, meet Martin's needs.

Martin could start using the system almost immediately. The system's price was

unexpectedly reasonable.

After three hours at Custom Designed Software $($CDS$),$ Martin left convinced that they

could produce exactly what he needed. Cost and time estimates were not established,

but CDS assured him that the cost would be reasonable and that the software would be

complete in a few months.

At Modified Software Unlimited $($MSU$),$ the owner said that customized software was

very good but expensive and that canned software was inexpensive but rarely met more

than a few needs. The best of both worlds could be achieved by having MSU modify the

package that came closest to meeting Martin's needs.

Martin returned to CME and asked Ricky about customized and modified software.

Ricky expressed enough concerns about both that Martin came full circle$-$to thinking

canned software was best. That night, Martin realized he could not make an objective

decision. He was swayed by whichever vendor he was talking with at the time. The next

morning he called you for help.

In practice, a system study must be conducted to determine what Martin needs before a

credible decision can be made about these alternatives. As part of this study you

decided to list the advantages and disadvantages of each of the approaches. Identify

two to three advantages and disadvantages for the three approaches described above.
