Critical Dependency on a Key Person or Supplier

Many organisations unknowingly concentrate IT knowledge and control around a single individual or supplier. Access rights, architecture understanding, and operating decisions slowly centralise.

As long as the relationship holds, the risk remains invisible. 

This is not a skills issue.  It is a structural dependency issue. 

When dependency becomes a governance problem 

Dependency forms when: 

  • one supplier “knows the whole system”
  • one internal expert resolves every exception 
  • documentation may exists but decision authority does not 

Over time, this weakens organisational resilience

When this typically appears 

This situation often arises in: 

  • fast‑growing SMEs
  • long‑standing supplier relationships
  • environments with informal escalation paths 

Why tools and documentation are insufficient 

Documentation reduces friction but does not transfer control. Dependency is reduced through vendor management, not tooling. 

Business consequences 

Key‑person dependency increases: 

  • continuity risk
  • negotiation imbalance 
  • decision delay under pressure 

At leadership level, the main issue is exposure, not replacement. 

Is this about trust? 

No. It is about structure and accountability. 

Is redundancy the solution? 

Only partially. Governance addresses the root cause.
