Devise comparison metrics

Know how to devise suitable metrics which can be used to assess the value or functionality of a system or activity or even thing. Also understand how to refine such matrix in the light of gained experience of their use.

Knowledge Node Summary

The derivation of metrics can be straightforward or it can be very complex. Typically complex problems are met when the system or thing is not well defined or contains ambiguities. For instance it might be quite straightforward (if not still difficult) to devise metrics to use to compare mobile phones. However, it would be much more difficult to devise metrics to compare problem solving methods.
