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

Assumptions

IRON LAW: Every Business Relationship Contains BOTH Cooperative
          and Competitive Elements

There is NO purely competitive or purely cooperative relationship.
A supplier cooperates (provides inputs) AND competes (captures margin).
A competitor competes (takes share) AND cooperates (grows the category).

Any analysis that labels a player as ONLY competitor or ONLY partner
is incomplete. Always map BOTH dimensions.

• Business is a game — but players can change the game, not just play it
• Value creation is cooperative; value capture is competitive
• The same player can be a competitor AND a complementor simultaneously
