The Vanishing Wizard
The only person who understands the pipeline just resigned
1Data teams haunted
10 of 20On the leaderboard
A brilliant, softly spoken sorcerer, it built half the platform from spells it never wrote down. When it finally vanishes in a puff of smoke and a farewell email, the incantations stop working one by one.
Symptoms
- Critical knowledge in one or two heads
- No documentation, tests or runbooks
- Work stops when they're on holiday
- Nobody dares touch their code
- Turnover drains know-how
Weakness
Spread the magic: documentation as code, runbooks, pairing and automated tests, plus a team that can share the load, so no spellbook walks out of the door.
Overheard in the corridor
- “Only one person knows how that works.”
- “Don't change anything until she's back from holiday.”
- “He left and took the pipeline with him.”
- “There's a document somewhere, probably.”
