Co-opetition: The Value Net (Brandenburger & Nalebuff, 1996)

Overview

Co-opetition recognizes that business relationships are never purely competitive or purely cooperative. The Value Net model extends Porter's focus on rivalry by adding complementors — players whose products increase the value of yours. The PARTS framework (Players, Added value, Rules, Tactics, Scope) provides a structured approach to changing the game rather than just playing it.

When to Use

Trigger conditions:

• User is analyzing a relationship that is simultaneously cooperative and competitive
• User asks about strategic alliances with competitors
• User needs to identify complementors or map all players in a value network
• User mentions "frenemy", "coopetition", "complementors", or "value net"

When NOT to use:

• For pure competitive analysis -> use Porter's Five Forces
• For internal organizational balance -> use grad-ambidexterity
• For international market entry mode -> use grad-oli
