When a regional director opens a branch scorecard, the deposit line often arrives as one thick bar spanning twelve months. That bar is accurate and almost useless for a Tuesday morning stand-up. Floor staff influence daily inflows through referral conversations, certificate rollovers, and the pace at which new accounts move from application to funded status. Those movements sit below the aggregate.
We split deposit variance into three layers on every scorecard we draft: household acquisition, balance migration from maturing products, and attrition after service incidents. Each layer gets its own small-multiple chart so a manager in Gangwon can see whether a dip came from fewer new accounts or from a cluster of transfers out.
The habit we encourage is to read variance right to left — most recent month first — and ask which layer moved before asking who moved it. That sequence keeps the conversation on controllable levers instead of weather metaphors.
