since I support external systems, obtaining a baseline looks like it will be a cross department and multi-year effort. I'm also not the manager, so the resources I invest in this might be allocated elsewhere. I do however really like the idea.

Besides the baseline, I prefer the method of looking at the big picture as was mentioned in the article. I prefer to avoid fixing the symptom when a bigger problem exists.

These are all Performance Monitor Counters and any experienced DBA will tell you the basic key to using them is not to over-react to them literally at any specific point in time. Otherwise, you are just going to be chasing wild geese all the time. The real secret to using them is to track them to a file over time and then examine the trends. SQL Nexus is just one tool that comes to mind that can help you with this. 😀
