institutional memory
The collective knowledge of an organization, often lost when people leave but retained cryptically by the code.
Detailed Explanation
Institutional memory is the shared understanding of why a system exists in its current state. It encompasses the history of architectural pivots, failed experiments, and bizarre business rules.
When institutional memory decays due to high turnover, the codebase becomes an archaeological site where current developers are afraid to touch anything because they don't know what it will break.
Why It Matters
Loss of institutional memory leads to the Chesterton's Fence problem: tearing down a component without understanding why it was built, inevitably causing a catastrophic failure.
Common Failure Mode
Practical Example
Production Manifestation
A new engineering lead deletes a 'redundant' cron job, only to discover a week later that it was the only thing preventing the payment queue from silently dropping transactions.
Frequently Asked Questions
What is institutional memory in short?

The company spends millions rebuilding a platform, only to slowly rediscover and re-implement all the edge cases that made the old platform 'ugly'.
