Personal poweris derived from an individual's unique qualities or expertise. It differs from positional power, which is based on job title or authority.Legitimate powerstems from an official position of authority, whileexpert poweris based on skills, knowledge, and credibility. These are both commonly used by procurement professionals to influence outcomes in negotiations.

“Expert power arises from experience, qualifications, or specialist knowledge that is recognised and respected by others. Legitimate power stems from a formal position or role within an organisation.”

(L4M5 Commercial Negotiation, 2nd edition, Section 3.1 - Sources of Power in Negotiation)

Note: Strategic and leverage power are more aligned with organisational positioning and external factors, not personal influence.

Having a BATNA:

Increases assertiveness (A): Knowing the fallback position empowers the buyer to negotiate more confidently.

Reduces the chance of a poor agreement (B): A BATNA ensures the buyer does not feel pressured to accept suboptimal terms.

Identifies walk-away points (F): It sets a clear boundary, allowing the buyer to exit negotiations if terms don’t meet minimum requirements.

These align with CIPS’s guidance on using BATNA to strengthen negotiation strategies.

In the scenario, the buyer states that permission from senior management is required to shorten payment period and she only has authority to sign off a deal in which the payment period lasts at least 30 days. The buyer is using lack of authority. The buyer also repeats the matter again throughout the negotiation. This is a common tactic known as broken record.

In 1959, French and Raven described five bases of power:

1. Legitimate – This comes from the belief that a person has the formal right to make demands, and to expect others to be compliant and obedient.

2. Reward – This results from one person's ability to compensate another for compliance.

3. Expert – This is based on a person's high levels of skill and knowledge.

4. Referent – This is the result of a person's perceived attractiveness, worthiness and right to others' respect.

5. Coercive – This comes from the belief that a person can punish others for noncompliance.

Six years later, Raven added an extra power base:

6. Informational – This results from a person's ability to control the information that others need to accomplish something.

In the scenario, Neville attracts and keeps good relationship with his colleagues not because of neither position nor reward nor coercion. He has good skills and kindness, which increase his charisma. His source of power is referent power.
