Just because no-one is complaining (that you know about) does not mean
that nothing is wrong. Within most organizations that I have been a part
of, the gap between the users and IT usually limited the communication
about performance problems. Users may become conditioned to accept
things the way they are and just complain amongst themselves and never
to management or IT. Management and IT don't seem all that eager to go
looking for problems, when they usually have enough to deal with already.
If we use the analogy of a health check in the medical fashion, we need
to consider the difference between reactive and preventative actions.
When we have pain, illness or something just does not feel right, we are
being reactive. We can describe the symptoms and have an idea of the
resolution (stop the pain, feel better, etc.). This is the strength of
Method-R (IMHO). It enables you to really drill down to a root cause of
the problem. What about times where something is wrong, but you either
ignore the problem (and accept it as a part of life) or don't have any
symptoms that you are aware of? Not to be morbid, but this illustrates
the point. Cancer of the stomach is one of the deadliest because
symptoms do not usually arise until it is too late. Aneurisms(sp?) in
the brain are very similar. There are tests to determine if there are
these types of problems, but I don't think they are all that common in
practice.
Just food for thought,
Daniel Fink
