What is Decision Theory?
The decision theory of management holds the belief that a manager should make rational decisions.
A manager involved in the decision-making process should make quality decisions that have a significant impact on managerial effectiveness, organizational efficiency, and productivity which are the basis of organizational success.
The decision theory of management was developed by Herbert Simon, in 1986, and was awarded the Nobel Prize for this outstanding work. Other contributors to this theory include Luther Gulick and Lyndall Urwick.
According to this theory, managers‘ primary responsibility in organizations is making decisions. When deciding on the organizational structure, establishing goals, putting plans into effect, launching new products, choosing new hires, investing in fixed assets, and many other daily tasks, they ought to be involved in the decision-making process.
A rational decision-making method entails choosing the best option from a set of available alternatives. A manager needs to make logical decisions.
Managers require a variety of tools and approaches to help them make decisions.
To make a sound decision, they can employ a variety of mathematical techniques, including probability, sampling, linear programming, game theory, etc.
Theoretically, a rational decision-making process that is tested to fulfill and constrained by bounded rationality is how ideal decisions are produced.
This method of decision-making presupposes that managers may encounter situations involving uncertainty, ambiguity, and non-programmed decision-making.
Beliefs, attitudes, abilities, routines, resources, and credentials may constrain a choice. The decision-maker is satisfied with their choice up until that point, when they tend to look for the next option, according to this theory.
Steps in Decision Making, According to Herbert Simon
Here are the steps of rational decision-making according to Herbert Simon, briefly explained:
- Define the Problem Clearly: Identify the root cause of the issue and understand its scope to ensure the problem is accurately framed before seeking solutions.
- Define Decision Premises: Establish the conditions, assumptions, and criteria that will guide the decision-making process. This creates a foundation for evaluating alternatives.
- Identify Relevant or Potential Alternatives: Generate a list of viable options or courses of action to address the problem effectively.
- Evaluate Alternatives: Analyze each option in detail by considering its pros, cons, feasibility, and alignment with organizational goals.
- Select the Best One: Choose the alternative that offers the maximum benefit and aligns with defined criteria and constraints.
- Implement: Execute the chosen decision, allocating resources and assigning responsibilities to ensure its smooth implementation.
- Evaluate and Review the Results: Monitor outcomes to determine whether the decision solved the problem. Adjust or refine the approach if necessary to optimize results.
Contributors of Decision Theory of Management
Here are five main contributors to the Decision Theory of Management, with their contributions:
Herbert A. Simon
Known as the founder of Decision Theory, Herbert Simon introduced the concept of bounded rationality, which explains that managers make decisions within the limits of available information, time, and cognitive ability.
He also developed a step-by-step model for rational decision-making and emphasized logical analysis to enhance organizational efficiency. His work laid the foundation for structured and systematic decision-making in management.
Luther Gulick
Gulick highlighted the importance of decision-making in managerial functions, emphasizing the need for managers to focus on planning and organizing decisions.
He integrated decision theory into the broader framework of management by proposing a structured approach to how managers should think and act to improve organizational outcomes.

Lyndall Urwick
Urwick extended Gulick’s ideas and stressed the scientific and rational aspects of decision-making in management.
He focused on aligning decisions with organizational goals and objectives while advocating for structured frameworks and principles to guide managers in making consistent and efficient decisions.
John von Neumann and Oskar Morgenstern
These mathematicians introduced the Game Theory, which became a vital tool in decision-making under competitive and uncertain conditions.
Their work enabled managers to analyze strategies, predict outcomes, and make informed decisions in competitive business environments.
This is especially useful in negotiations, resource allocation, and market strategy.
Peter Drucker
Drucker emphasized the significance of effective decision-making in achieving organizational goals.
He highlighted that decisions should be forward-looking and consider their long-term impact on organizational performance.
Drucker also emphasized the importance of evaluating alternatives and understanding risks while making decisions to ensure sustainable success.

Contributions of Decision Theory
Below are the five main contributions of decision theory in management:
- Provides a rational and systematic framework for decision-making.
- Encourages the use of mathematical tools for evaluating alternatives.
- Enhances managerial effectiveness by focusing on logical problem-solving.
- Assists in making decisions under uncertainty and ambiguity.
- Emphasizes the importance of bounded rationality in realistic decision-making scenarios.
Limitations of Decision Theory
This theory also has some limitations:
- Limited focus on economic rationale, neglecting other organizational factors.
- Narrow scope, primarily concentrating on decision-making processes.
- Assumes complete information, which is rarely available in real-world scenarios.
- Overemphasis on rationality, ignoring human emotions and unpredictable behaviors.
