Not sure if this went out to the list, so sorry if sent twice.

Subject: RE: Training for Oracle Performance tuning - Method-R is easy

Your answer seems contradictory at first and I think you've also made my point.

"Not everyplace.... requires or expects all changes to return measurable value to the business." "It's not at all unusual to make a change that will return no measurable improvement right now, but at some future date, should we need it, that extra unused capacity will be available"

I think the value to the business is that there is extra capacity, but how do you know that the change will add extra capacity and not have an opposite effect? Are you testing or hoping the change will work. If hoping, this is not Method-R. As long as the work adds value in the long run, isn't that value? The "should we need it" part scares me. So the business pays up front for unused capacity that they may not need. Disaster planning is like this and in business there is always risk, but that risk is assigned a cost by the business. If there is current value in idle potential I think that thinking will be going to the wayside as better options become available.

I suggest reading "The Goal" or taking a look at http://en.wikipedia.org/wiki/W._Edwards_Deming

If testing, Method-R applies in your case as well.

Well, there you go. By your answer, you make my point. It's a matter of philosophy. Not everyplace I work requires, or even expects, all changes to return measurable value to the business. The expectation is that by keeping an eye on performance, and continuously improving where possible, we increase our capacity and ability. Its not at all unusual for me to make a change that will return no measurable improvement right now, but at some future date, should we need it, that extra unused capacity will be available.

In some environments, where staffing is low and you are right at the edge of capacity all the time, you may not have time to work that way.
