Expert power
Expert power is influence based on others’ perception that a person has relevant knowledge or skill. It can exist without a management position and is often specific to a subject or situation. Its strength depends on credibility and relevance, not simply possession of a qualification. Good decision-making still tests evidence and recognises the limits of any specialist’s expertise.
Worked example
A maintenance engineer’s assessment carries weight when managers decide whether a machine can operate safely. The same expertise does not automatically make the engineer an authority on the company’s tax strategy.
Common mistake
Do not treat expertise as unlimited across subjects or confuse a confident assertion with demonstrated competence. Formal decision responsibility can remain with another person.
