Integration Hell
Noun · Slang & Abbreviations
Definitions
A miserable state caused by mismatched systems, awkward contracts, poor docs, brittle auth, and all the other pains of making separate things work together. In engineering slang, integration hell is where simple promises go to become multi-quarter programs.
In plain English: A miserable situation caused by making different systems integrate poorly.
