80%
informal knowledge
Most critical know-how is neither written down nor transmissible: it lives in people's heads.
Decision-maker guide · Executive leadership
Make your performance independent of key people.
You've already put everything in place — processes, a quality system, tools, KPIs. And yet your performance still depends on people. When 80% of critical know-how stays informal, every departure, every absence, every handover weakens the whole organization.
2.7 years
median tenure with the same employer for 25–34-year-olds (versus 9.6 years for 55–64-year-olds): know-how changes hands faster and faster.
When the expert who "knows how" leaves, it isn't just a position that empties out: it's a part of the company's performance that disappears. And because that knowledge was never formalized, it takes months — sometimes years — to rebuild, at the price of errors and poor quality.
The real problem
80% of critical know-how stays in the heads of a few people. Completed ≠ mastered.
Key-person risk isn't just an HR risk: it's a risk to operational continuity. Fewer than 30% of processes are actually run consistently, and up to 50% variability separates two operators on the same gesture. As long as knowledge stays informal, your performance hangs on the presence — and the memory — of a few individuals.
< 30%
consistent processes
Without captured know-how, everyone executes "their own way" — performance becomes a lottery.
up to 50%
variability
The gap between operators on a critical gesture measures your dependency on key people.
The know-how chain
Four links, people at the center.
Performance plays out along a chain of four links. As soon as one link depends on a single person, the whole chain becomes fragile.
Process
What should really happen on the floor — rarely written down as it is actually executed.
Procedures & know-how
The most fragile link: 80% of critical knowledge stays informal and non-transmissible here.
Execution
Every operator should execute the same way, at the right level — across all sites.
Deviations
Detect, handle and learn from deviations to turn risk into a shared asset.
From risk to response
Where dependency hurts — and how to remove it.
Every form of key-person dependency has a concrete answer: capture the knowledge before it leaves.
| Dependency situation | Consequence | Sinfony response |
|---|---|---|
| Departure or absence of an expert | Lost knowledge, lower performance. | Capture the critical know-how before the departure. |
| Long & costly onboarding | Slow ramp-up, errors. | Documentation and training: −50% onboarding effort. |
| Critical gesture "in the hands" | Variability and poor quality between operators. | AI video and micro-learning to transmit the gesture. |
| Bulky SOPs not followed | Gap between documentation and practice. | Simplification: −50% SOPs, −90% doc/training gap. |
| Knowledge not audit-ready | Inspection risk, fragile traceability. | Auditable certificates and audit-ready traceability. |
Why act now
Knowledge is becoming a volatile asset.
2.7 years
median tenure with the same employer for 25–34-year-olds — versus 9.6 years for 55–64-year-olds. The generations that hold the knowledge are leaving as newer ones churn faster.
39%
of skills will be transformed or obsolete by 2030 — transmission can no longer rest on the presence of experts alone.

Where to start
Three levers to secure knowledge.
Making performance independent of people starts with documenting, training and capturing.
Know-how
Document, train, capture
Make the informal critical knowledge of today transmissible: −50% SOPs, −90% doc/training gap.

What executives ask us.
It's the situation where the organization's performance or compliance rests on the know-how of a few people. Since 80% of that critical knowledge stays informal, their departure, absence or handover lowers performance and increases poor quality. It's a risk to operational continuity, not just an HR risk.
Because an SOP describes what to do, not how the gesture is actually performed. Completed ≠ mastered: fewer than 30% of processes are run consistently and up to 50% variability remains between operators. The real know-how — the kind that drives quality — stays in people's heads until you actively capture it.
By getting down to the critical gesture as it is actually performed at the workstation, then making it transmissible: simplified documentation, micro-learning and AI video to capture the gesture, traceable and audit-ready training. You capture the knowledge before the departure, share it with everyone, and verify mastery — not just training attendance.
