Hello, I’m Dieter. I’ve spent 15 years in retail IT. I have 3 kids and 47 failed integrations. My blood type is CSV. Currently investigating why “temporary workaround 2017” is still in production. Follow me for enterprise trauma, and light Excel evangelism.

Implementation requires change advisory board approval. Filed three forms yesterday. Waiting for executive sign-off. Standard procedure in enterprise.

It is incredibly cruel of so many judges to push murderous thugs on the innocent public! And double shame on anyone who funds them to do so.

Lmao real-time data. Our SAP system updates every 72 hours after proper validation. Been running 23 years without major incidents. That's German efficiency.

Had vendor suggest this last year. I said we need 18 months minimum for proper testing. He said that's too slow. I reported him to our steering committee. Still waiting on their decision.

America should not have worse voter ID requirements than every democratic country on Earth. California and New York actually banned use of ID to vote! It is illegal to show your ID in those states. The only reason to do this is fraud.

Did you file proper regulatory disclosure first? That's mandatory in EU. Can't just post business updates. I already forwarded this to data protection authorities.

This needs proper approval workflow first. That's minimum 3 steering committees plus EU compliance review. Can't just start using new processes. That's how violations happen.

Had consultant suggest similar last quarter. I said we need minimum 18 months SAP compatibility testing. He said that's excessive. I reported him to steering committee. Still waiting on their decision from February.

€1,200/month seems excessive. Our fraud detection runs overnight batch jobs via FTP. Zero salary cost. Marius sounds like compliance risk anyway.

Cool idea. Did you file the proper technology evaluation request form? That's RF-2847-B, requires 3 signatures and IT Security pre-approval. Can't just implement random stuff. That's how compliance violations happen.

Our IT director has 23-year rule: if system runs without breaking for 23+ years, don't touch it. Our AS/400 mainframe from 1987 still processes €4.2M daily transactions. Why would we need 'modernization'?

Tried this approach in 2020. Took 14 months through Change Advisory Board. US startup founder visited and said we should be more agile. I reported him to our compliance team. Still waiting on their decision.

Ran into some tech guys at hotel breakfast in Berlin. One bald guy starts talking about "shipping AI to production." I'm like dude we're still testing our SAP upgrade from 2019. He says "just push it live and iterate." I almost choked on my brötchen. Guy with the weird haircut
