Operations built a churn predictor trained on 40 rows

“It's only one database.”— Tobias, Operations

Reason:

Allegedly because the workflow has 84 steps and nobody wants to open it. Quietly rolled out to two countries.

Built by:

Tobias, an intern

Build time:

8 minutes

Built with:

a no-code builder on a personal account

Database:

localStorage. That is the whole backend.

Authentication:

the security model is "nobody knows this URL"

Deployment:

deployed into production because staging was broken

Responsible:

Katrin, who thought somebody else owned it

Documentation:

a Miro board with 147 sticky notes

Security situation:

security is handled by a checkbox called admin

Future disaster:

It will become part of the company's "digital core" slide deck.

Age: 45 days · originally expected to last 3 weeks · 2 owners so far · survived 1 reorganisation · last meaningful change 45 days ago · original builder left 39 days ago
