Philosophy
Organizations have always reflected the assumptions they were designed around.
As those assumptions change, so must the way organizations create value.
Theory A begins with a different question.
Theory X and Theory Y fundamentally changed how leaders thought about managing people. They emerged from different assumptions about work, motivation, and organizational life.
Theory A builds on that history, but it addresses a different challenge. Rather than asking how people should be managed, it asks how organizations themselves should be designed.
Three questions. Three eras. Three philosophies.
Theory X
Question
How do we motivate people to work?
Characteristics
Douglas McGregor introduced Theory X in 1960 to describe the dominant assumptions of industrial-era management. In that context, control was the central design problem: how to direct the effort of people who required close supervision, standardized processes, and external rewards to perform. The organization was designed to extract labor under conditions of scarcity and limited information.
Theory Y
Question
How do we enable people to contribute?
Characteristics
McGregor's Theory Y proposed that people are intrinsically motivated and capable of self-direction. It emerged as knowledge work grew in importance and organizations recognized that engagement and participation produced better outcomes than compliance. The design problem shifted from control to enablement — and the organization was redesigned around human potential rather than human compliance.
Theory A
Question
How should organizations be designed so agency creates value?
Characteristics
Theory A addresses a different question for a different era. AI is making previously scarce capabilities abundant. Organizations designed around the constraints of the past — limited intelligence, limited expertise, high coordination costs — must now be redesigned around new ones. The challenge is not how to control or enable people. It is how to design organizations so that human and artificial agency, acting together, can continue to create value as conditions change.
Theory X and Theory Y are theories of motivation.
Theory A is a philosophy of organizational design.
The central idea
Organizations have never created value simply because they possessed intelligence.
They create value by organizing agency toward meaningful outcomes.
For most of management history, knowledge and skill were scarce — and organizations competed by acquiring them. AI changes that. Knowledge and skill are now broadly accessible. What remains scarce is the judgment, purpose, and imagination required to put them to use. That is why agency has become the defining constraint of this era — and why organizational design, not technology adoption, is the central leadership challenge.
But organizations continue to create value through the ability of people — and increasingly intelligent systems — to act together toward shared outcomes.
The question is not whether conditions will change. The question is whether organizational design evolves so agency can continue to flourish.
From philosophy to practice
Theory A does not prescribe a single organizational model. Instead, it offers five enduring design principles that help leaders rethink organizations as conditions evolve.
These principles examine:
Each principle asks a different design question. Together, they form a connected system for designing organizations capable of organizing agency under changing conditions.
