I've probably posted this reference before, but Roger Martin wrote a good article comparing two ways of thinking about problems and processes. He calls this dynamic reliability vs. validity.
"Reliability seeks to produce consistent, predictable outcomes by utilizing a system that is restricted to the use of objective data.... "Validity, on the other hand, seeks to produce outcomes that meet the desired objective, even if the system employed can%u2019t produce a consistent,predictable out- come." Personas are a classic example of a method that is "valid" in Martin's terms.
