Better Than Top Quartile

Just time to mention briefly that Jedd Fowers has a good article on quartiles in price benchmarking at http://www.globalservicesmedia.com/Content/general200806274540.asp.

It should be read along with David Roger's explanation at http://www.rogersteam.co.uk/ (Advice On Deciles In IT Benchmarks) to understand why the number of peers in the peer group can cause decile and quartile values to change substantially and unpredictably.
