Retainer Margin Erosion Under Unbounded Client Communication Channels
Retainer margin erosion occurs when open client communication channels create unbilled context switching that consumes execution capacity without pricing adjustments.

Retainer margin erosion occurs when open client communication channels create unbilled context switching that consumes execution capacity without pricing adjustments.

Context switching friction is an ordinal cognitive cost that converts to cardinal sprint forecasts through calibrated recovery latency bands.

Resource saturation requires restructuring fixed milestones into modular deliverables or capacity bands, preventing unbudgeted labor from destroying engagement margins.

Fixed enterprise contracts conceal human depletion by exchanging cardinal revenue for unmeasured cognitive exhaustion unless strict operational limits protect capacity.

Unbounded multi channel client communication inflates internal labor hours through context switching, compressing fixed retainer margins unless structured portal restrictions convert communication overhead into explicit cardinal pricing terms.
