How Brian approaches a problem

Solve the cause, not just the symptom

A point-of-use water-quality issue usually begins somewhere else entirely. Pretreatment, purification, storage, distribution, controls, monitoring, maintenance, operating practices, and documentation can all influence the result.

A Systems Thinking approach traces those relationships, identifies causal loops, and evaluates the consequences of a proposed change before recommending corrective action.

Utilize Systems Thinking to trace the evidence to the root cause Identify causal loops and interactions between and across system components
