  • What are Best Practices?

    The casual observer may interpret the term “Best Practices” and consider that such a concept is subjectively slanted with many personal points of view. Within the context of the JPT White Paper and Case Study Offerings are experiences drawn from successes as well as failures since our founding in 1971.
