Diane has been at the agency for nineteen years. She is the one who knows that the manufacturing account with the tricky umbrella renews off-cycle in March, that the carrier underwriter on the restaurant book only picks up the phone before ten, and that the "Sunrise Bakery" the new producer keeps asking about is filed under the owner's holding company. When a policy question comes in that no one else can answer, it goes to Diane. When Diane is out, a small number of things quietly do not happen.
This is the arrangement at most agencies, and it feels like a strength. Diane is your best CSR. What it actually is, is your single largest concentration of undocumented, load-bearing knowledge, sitting in one person's head, with no backup copy.
The better they are, the more the agency routes through them
There is an uncomfortable dynamic in how a great service person becomes great. Over years, they absorb the exceptions. They learn which clients need a call instead of an email, which carrier forms have a quirk, which renewals blow up if you miss a date. The agency notices they are reliable, so it sends them more of the hard cases. The hard cases are exactly the ones that never got written down, because writing them down was slower than just handling them.
So the best CSR accumulates the parts of the operation that the system never captured. Not because anyone decided to concentrate risk there, but because that is where the exceptions naturally pooled. The pattern is not specific to insurance. Panopto's Workplace Knowledge and Productivity research, a broad survey of U.S. knowledge workers, found that 42% of the institutional knowledge people use to do their jobs is unique to them and shared with no one else. Read it as a proxy rather than an agency-specific measurement, but the pattern is exactly the one an agency runs on. Much of what Diane knows exists only in Diane.
That same research found knowledge workers lose about 5.3 hours a week waiting on information from a colleague or recreating something that already existed somewhere. In an agency, that lost time has a face. It is the producer standing at Diane's desk because the account history in the AMS does not tell the whole story, and Diane does.
The risk is not hypothetical, and it is getting worse
None of this matters until Diane leaves, and Diane is more likely to leave than she used to be. By Staff Boom's summary of industry workforce data, insurance turnover has roughly doubled over the past decade, from a historical 8 to 9% to a more typical 12 to 15% today. Insurance brokerage turnover reached 16.4% in 2024, per MarshBerry's Agency and Brokerage Compensation Report as reported by Sonant. The people you most want to keep are moving more than they once did.
And the deeper problem is demographic. Your most experienced CSR is usually closer to the retirement-risk cohort than your newest hires are, and that cohort is heading for the door together. Roughly one in four insurance professionals is already 55 or older, and about half of the current workforce is expected to retire over the next 15 years, leaving more than 400,000 positions unfilled (Jonus Group). Your most valuable CSR is not just hard to replace. They are disproportionately likely to sit in the quarter of the workforce closest to retirement, which means the risk is not hypothetical and it is not far off.
What it costs when the copy is lost
When Diane goes, the agency pays twice. The first bill is the ordinary replacement cost. Gallup puts the cost of replacing an employee at one-half to two times their annual salary, and calls that a conservative estimate. Recruiting in insurance alone runs around $4,700 per hire, by Sonant's estimate. A replacement gets roughly two and a half months of formal training and can take up to six months to reach full productivity, on paper.
The second bill is the one that does not show up in any spreadsheet. The new hire can learn the AMS in a week. What they cannot learn in six months is the mental index, the nineteen years of which client, which carrier, which exception. For a stretch after Diane leaves, the agency is slower, makes more errors, and drops things it used to catch, not because the new person is weak but because the map lived in the person who left, and the map did not come with the job.
Documentation helps, but it is not the fix
The standard answer to key-person risk is "write it all down." Build the process manuals, the SOPs, the shared drive of tribal knowledge. Every agency has tried some version of this, and the folder is always out of date, because documentation is a task that loses every time it competes with actual client work. Under load, Diane handles the account. She does not stop to narrate why. The knowledge is generated faster than anyone can transcribe it, and most of it is tacit anyway, the kind of thing you would not think to write down because it is just how you do it.
None of this means documentation is worthless. Written procedures are worth having, and every agency should keep them current. They just are not sufficient on their own, because you cannot document your way out of a structural problem. The reason the knowledge lives in Diane's head is that the system was never in a position to capture it in the first place. It is a database with forms in front of it, waiting for a human to decide what matters and type it in. When the human is fast and busy, most of what they know never touches the record.
Make the value real without making it fragile
The goal is not to make Diane less valuable. It is to stop her value from being a single point of failure. That happens when the connective work she does by reflex, matching the email to the right account, filing the document against the right policy, noting why this renewal is off-cycle, gets done in the system as it happens, rather than in her head and nowhere else. Then the knowledge accrues in the record instead of in the person. The account tells its own story. The next CSR opens it and sees the history, the exceptions, the reasons, without needing a month of asking the person at the next desk who Sunrise Bakery really is.
Diane is still your best CSR. She just stops being the only copy. Her judgment, the part that is genuinely irreplaceable, sits on top of a system that holds the context, instead of substituting for one. When she takes two weeks off, the accounts do not go dark. When she retires, she leaves behind the map, not just the memory of having had one.
Your best person should be your best person. They should not also be your biggest risk.
