Most analysts of corporations and industries adopt the focal perspective of a single prototypical organization. Many analysts also study corporations primarily in terms of their internal organizational structures or as complex systems of financial contracts.

The result is a rich rendering of analysis that portrays whole populations and communities of corporations.
