To complete the line match

Click on the match in the second group

To delete a match, double click on a line

Cluster

Low quality, high business value

High quality, high business value

High quality, low business value

Low quality, low business value

Recommended action

Scrap these systems since they are expensive to keep with low return

Reengineer or possibly replace these systems since they are important but costly to maintain

Continue normal maintenance since high quality avoids the need for transformation

Continue normal maintenance unless expensive changes are needed, in which case scrap

A university uses a student registration system only once a year, at the start of the academic year. Why would it be a mistake to assume this system automatically has low business value just because it is used infrequently?

Because all systems used less than daily are required by law to be replaced

Because annual systems cannot be assessed for business value under any circumstances

Because infrequent systems always have higher technical quality than frequently used ones

Because infrequent use does not necessarily mean low importance; the system may be essential despite being used only occasionally

A company has a system that tracks customer orders and automatically generates reorder reminders, resulting in many repeat orders and high customer satisfaction. According to the business value framework, what does this indicate about the system?

The system has no business value because it does not directly generate revenue

The system has low business value because reminders are a minor feature

The system has high business value because its outputs are important to the successful functioning of the business

The system's business value cannot be determined without knowing its original cost
