Why use a Performance Based Measurement System (PBMS)?

Why use PBMS?

 

In 1997, the Agency adopted the Performance Based Measurement System (PBMS) (i.e., Federal Register Notice of Intent) to:

  • Reduce the cost of monitoring;
  • Stimulate the development and use of innovative technologies;
  • Speed up the introduction of new methods; and
  • Improve the quality of science in the monitoring community.

Unfortunately, the "one size fits all" approach did not work for the diversely different programs and authority within each Agency office. The guidance document “Flexible Approaches to Environmental Measurement”, created in 2008 shifted the focus from the performance approach to a more flexible one. Documentation on the Agency’s commitment to this flexible approach can be found at:
