How do you track customer sentiment shifts in the chip shortage era?

We've been running quarterly pulse surveys (50-100 questions max) combined with social listening through Brandwatch to catch real-time sentiment shifts. Honestly, what we're seeing is that brand loyalty softens fast once lead times hit 16+ weeks — buyers start exploring alternatives they'd never have touched before. Tracking 'consideration set expansion' as a specific metric has been really telling for our clients in this space.
