Key points
- Owner dependency concerns the owner; key person risk concerns anyone.
- Reducing one can move risk to another person.
- Buyers and successors usually examine both.
- Cross-training and documentation help with each.
The two ideas overlap but are not the same. Owner dependency is one form of key person risk — the one that matters most when ownership changes.

Owner dependency vs key person risk
Who it concerns
- Owner dependency
- The shareholder or owner
- Key person risk
- Any individual — owner, manager, engineer or salesperson
When it matters most
- Owner dependency
- On retirement, succession or sale, when the owner leaves
- Key person risk
- Whenever that person might leave, fall ill or be unavailable
Typical signs
- Owner dependency
- Decisions, customers and knowledge centre on the owner
- Key person risk
- One person holds a critical skill, client or system
Typical response
- Owner dependency
- Delegation, handover and management development
- Key person risk
- Documentation, cross-training, retention incentives and cover
Why does the distinction matter?
An owner can reduce their own dependency only to find the risk has moved to one manager or salesperson. A buyer or successor will usually look at both: whether the business needs the owner, and whether it relies on any other single person.
How do you reduce key person risk?
- Identify roles where one person holds critical knowledge or relationships.
- Document and cross-train.
- Spread key customer relationships across more than one person.
- Consider retention arrangements for people a successor would need.
- Review employment contracts and notice periods with an employment adviser.
