Coordination and Control Bases

In the model of team production, activities are coordinated and determine the productivity of team members. Determining the individual productivity of team members is hampered by technical issues and opportunistic behavior.

To produce efficiently, companies must manage two types of costs:

• Costs of collective action
• Control costs

Competitive Forces Shaping Industries

1. Degree of Rivalry Among Competitors

   The intensity of competition in a sector depends on the number of competitors and the market growth rate. The market growth rate also influences the degree of concentration in the sector, determining how the market is distributed among competitors. The greater or lesser competitive pressure often depends on the maturity of the sector.

2. Threat of New Entry

   The entry of new competitors increases competitive pressure. The easier it is for a company to access a major sector, the greater the competition. Factors that create barriers to entry include:

   • An established edge of differentiation.
   • Lower costs for existing firms.
   • Firms with long-standing products and strong experience in the
