"This was complicated by some banks finding it surprisingly difficult to add numbers quickly… We have a report of Friday outflows, but it gets crunched by an ETL job which only finishes halfway through Saturday, and Cindy who understands all of this is on vacation, and… and eventually very serious people said Figure Addition The #*(%#( Out And Call Me Back Soonest"
As someone who has written ETL jobs for banks, this hits home.
- SilasX 4y agoI thought financial companies had regulations against bottlenecks like that? Something like, every employee has to have their access turned off for one uninterrupted week, to ensure they didn't leave something in that depends on them or they're controlling a (fraudulent) process no one else knows about?
- WorkerBee28474 4y agoYes, the week (two weeks, IME) is a thing. As are contractor term limits. They reduce key man risk and keep knowledge internal. Still, it's possible to write a script to do something and then just not touch it for years. It keeps chugging away, and the mental model of how it works is lost to time or employee churn, and nothing goes wrong enough that anyone has to dig in and really understand it again.
