Cluster

Low quality, low business value

Low quality, high business value

High quality, high business value

High quality, low business value

Recommended action

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

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

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

Continue normal maintenance since high quality avoids the need for transformation

When plotting business value against system quality for a portfolio of legacy systems, four clusters emerge. Match each cluster to the recommended action.

Infrequent but Essential System Use

1 pts

volume_mute

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

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

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

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