It takes months before a new colleague works independently
Onboarding that takes months is rarely a training problem. The basics are taught quickly. What takes long is learning everything nobody wrote down — the exceptions, the customers, the unwritten rules — from experts who have little time to explain. The cause is where the knowledge lives, not how fast new people learn.
Do you recognise these signs?
- new colleagues shadow one expert for weeks;
- they keep asking the same questions to the same people;
- every newcomer learns a slightly different version of the job;
- the expert's own work slows down whenever someone new starts;
- people leave before they ever feel confident.
Why does it happen?
The knowledge a new colleague needs most sits with experienced people, so learning speed depends on their availability. On a busy week, onboarding simply pauses.
Training material helps with the basics but rarely covers the unusual case, which is where newcomers get stuck — see training material vs digital knowledge copy.
What does it cost?
The obvious cost is time: months before a new colleague is fully productive, and expert capacity spent on explaining. The less visible cost is inconsistency — each newcomer does the job a little differently.
Over time it limits growth: a company can only take on as many new people as its experts can absorb, and people who feel lost for too long are more likely to leave.
The first step, this month
Ask your most recent hire which questions they asked most in their first months. Then ask the expert who answered them to write down their answers, including the exceptions.
That list is the start of an onboarding that no longer depends on one person's calendar — and it shows which knowledge to capture first.
How MentX helps
MentX captures how your company really works: the knowledge of your key people and the processes they run. We offer both a hands-on service approach — mapping your processes and capturing the knowledge behind them, from meetings, workshops and a guided intake — and our own personality-aware knowledge base, with full source attribution, in your own Knowledge Space. We build on the tools you already use and add best-practice solutions where they fit.
We capture the knowledge newcomers need from the experts who hold it, with sources, and map the onboarding process itself. New colleagues get answers without waiting for the expert; see onboarding new engineers.
A question we often hear
Can onboarding ever be fast in a specialised company?
Faster, yes; instant, no. Some knowledge only comes with practice and real cases, and a good mentor stays essential. What can change is how much of the waiting is spent on questions that already have an answer somewhere — in one expert's head. Capture those answers, and the mentor's time goes to what really needs a mentor.
