What you don't see on the dashboard
The most expensive things in an org are stored in two places no one audits: someone's head, and the chat thread no one searches anymore. Years of small decisions, edge cases, and "we tried that in 2024 and here's why we stopped" β none of it lives in a document.
When that person leaves β for a competitor, for a sabbatical, for any reason β the org doesn't get a warning. It just gets slower. Decisions take an extra day. New hires take three months instead of three weeks to be productive. The replacement asks questions no one can answer, because the answers were never written down.
Knowledge walks out the door. The documentation stays. They were never the same thing.
A specific shape we keep seeing
A sales-ops lead leaves on good terms. Two weeks later, an enterprise renewal stalls because three discount rules were "rules of thumb" she carried in her head. The COO spends six weeks reconstructing the why β talking to four different teammates, reading old Slack threads, and finally messaging the ex-employee on LinkedIn.
The cost is not the renewal. It is the six weeks of leadership attention diverted from the next quarter.
The pattern repeats with the engineer who set up the data pipeline, the recruiter who knew which sourcing channels actually worked, the product manager who remembered why a feature shipped half-finished. None of it was secret. All of it lived inside one person.
Why wikis don't fix this
Plenty of orgs have wikis no one reads. The problem isn't a missing document β it's that context (the why behind a decision, the history that justifies the current shape of things) has nowhere to live except inside people. Wikis store the what. They almost never store the why.
