Hi folks,

In your experience as a problem manager, which is more effective, an incident volume based approach or a ticket severity based approach when looking problem trends?

Which approach produced more results? and how fast?

thanks.

How do you define "results"?

The point about problem management is to reduce risks and costs. Neither incident volumes nor ticket severity on their own help much to determine which problems to prioritize.

If a repeat of a high severity ticket [A] will cost a thousand pounds, and a repeat of a low severity ticket will cost a hundred pounds, then, if the likelihood of B is eleven times that of A, you will save the business more money by resolving B before A than the other way round.

The same logic applies if both incidents were in fact classed at the same severity. At the best of times, severity is a blunt instrument. In this context it is no instrument at all. Problem management should be analysing with much greater maturity than that.
