The tool's development was basically from the period after the audit came out, starting in about 2011. We completed the tool's development in 2014 with the second, enhanced version of the risk-based basin assessment. We are now in the process of integrating and finalizing this tool.
It is a dynamic system. We call it a “plan-do-check-improve” model. It doesn't actually finish. We go back to the beginning and start over again so that we are constantly at the leading edge.
