To clarify - the compensation of lending officers, branch managers, tellers and etc. may not be commission-based, but - in my experience - there are dang few bank employees who interact with banks' customers who do not have some sort of production incentive/disincentive in their compensation and promotion potential matrices. My view of it is that there will be pressures that emphasize production rather than compliance as long as (1) banks' performance reporting emphasizes short term results (the quarterly report) and (2) as long as the principle decision makers (CEO, COO, Pres, department or loan type managers) have compensation packages that have any component related to volume and/or transaction profit - whether that incentive is paid as a portion of income, as a bonus or other incentive related to achieving production/profit goals, stock performance, market share increase or whatever.
That's my opinion - you're welcome to make it yours, to prove it wrong, or to argue a different experience.
