Super interesting concept, because these complaints tend to end up at the bottom of top management backlog due to amount of time and attention required to analyse these. In real life it just does not work unless your org is in the low hundreds of customers.
This could change if technology could solve aggregation and analysis problem, making ready-made decision propositions to management. High risk of this mechanism just becoming another accountability sink, though.
Another solution is to build large organisations out of federated micro-orgs, where such intristic responsibility is feasible.
