The Decision-Making Loop on Shift
A lead's primary job is to make faster, better decisions than an operator working alone — knowing when to escalate is part of that.
Define which decisions the shift can make autonomously (DO adjustment, RAS rate change, sample timing) versus which require a call to the superintendent or on-call manager (treatment bypass, chemical spill, permit deviation).
Make it normal to verbalize your reasoning when you change a setpoint so the operator next to you learns the thought process, not just the result.
Build a 'when in doubt, ask' culture early. A lead who punishes questions gets the next question skipped and learns about the problem from a DMR instead.
If you change direction mid-shift, tell the crew why. A silent setpoint change with no explanation trains operators not to trust their own eyes when they spot something different next time.
