Finance built a lead scoring model nobody understands

“It's not shadow IT if the manager knows about it.”— HR Generalist

Reason:

Allegedly because the audit is in 10 weeks. Started as Leads_final_FINAL.xlsm with a script attached.

Built by:

Marco, a field technician

Build time:

7 evenings

Built with:

React, Vite and enthusiasm

Database:

two databases kept "mostly in sync"

Authentication:

the refresh token never expires, for convenience

Deployment:

on the marketing website's server, somehow

Responsible:

Anja, who inherited it from Marco by accident

Documentation:

a Word document with tracked changes still enabled

Security situation:

MFA exists for the admin account, which everybody shares

Future disaster:

It will send 143,465 duplicate emails.

Age: 17 days · originally expected to last 3 weeks · 2 owners so far · last meaningful change 17 days ago · original builder left 34 days ago

Rated common mostly because: €157k per year, 4 departments depend on it, the builder has left.
