The Bureau of Labor Statistics reports that in January 2024 the median American wage and salary worker had been with their current employer for 3.9 years — the lowest since 2002. For workers aged 25 to 34 it was 2.7 years, and twenty-two percent had been in post a year or less. Half the workforce leaves within four years. Whatever they learned goes with them, and the organization is left with whatever it happened to write down.
Tribal knowledge
The standard American phrase for what a company knows but has not recorded. It appears in engineering, manufacturing and software without irony. The metaphor concedes the whole thing: the knowledge is oral, held by initiates, and passes by contact rather than by document.
Knowledge management
An entire American consulting and software industry exists to capture what employees know before they leave. It arose in the 1990s and has been repeatedly reinvented, which is itself evidence. A problem that stays solved does not need solving every decade.
Onboarding
American organizations have a named, designed process for bringing a new person up to speed, with owners, checklists and a timeline. It is a large investment in transfer, and it exists because transfer happens constantly.
The exit interview
A formal conversation held on the way out, partly to learn why the person is leaving and partly to extract what they know. The timing is the point: the attempt to capture the knowledge begins after the decision to leave has been made.
Political appointees
Each incoming US administration replaces several thousand positions across the federal government, down into the working levels of departments and agencies. Other democracies change the government and keep the officials. The American system rebuilds a substantial part of the executive with every election.
The Center for Army Lessons Learned
The US Army maintains a permanent organization at Fort Leavenworth whose function is to collect what units learned in operations and push it back out to units who have not yet deployed. The Army also runs the after-action review as standard practice after any significant event.
The counter-example is instructive. Where the cost of forgetting is measured in lives, the American institution builds the archive deliberately — which suggests the corporate habit is a choice rather than an incapacity.
Documentation debt
American software culture has a word for the accumulated cost of undone documentation, and it is borrowed from finance. Debt is something you take on deliberately, in order to move faster now, intending to pay it back later. Most of it is never paid back, and everyone involved knows that when they take it on.
Consultants
American corporations spend heavily on external advisers who arrive, learn the business, produce recommendations, and leave. A recurring complaint inside those companies is that the consultants are selling back knowledge the firm once had. The complaint is often accurate, and the spending continues.
Reinventing the wheel
The phrase exists in American English as a criticism, and it is used constantly — which means the thing it describes happens constantly. A culture only develops a ready reproach for a failure it commits often.
