What is Decision Theory? Definition, Contributors, Process, and Pros/Cons

What is Decision Theory?

The decision theory of management explores how choices are made within uncertain and unknown environments. It combines mathematical, philosophical, statistical, and psychological tools to understand the decision-making process. By analyzing an individual’s beliefs, attitudes, and desires, decision theory helps determine the best logical decision possible in unpredictable circumstances.

Simply put, decision theory is that theory that emphasizes managers make rational decisions out of any circumstances that best deliver value to the organization.

This theory emphasizes that managers should make rational decisions to enhance organizational effectiveness, efficiency, and productivity. Herbert Simon, a prominent contributor to this theory, was awarded the Nobel Prize for his significant work. Other notable contributors include Luther Gulick and Lyndall Urwick.

According to the decision theory of management, decision-making is a crucial responsibility for managers in various organizational aspects, such as establishing goals, implementing plans, introducing new products, hiring employees, and investing in assets. Managers play a vital role in the decision-making process, shaping the success of the organization.

Herbert Simon

  1. Developed the concept of bounded rationality, which recognizes that decision-makers have limitations in processing information and therefore make decisions based on satisficing (achieving satisfactory results) rather than optimizing.
  2. Introduced the idea of decision-making as a process of searching and evaluating alternatives to find a satisfactory solution.
  3. Pioneered the application of computer simulations and artificial intelligence to decision-making processes, contributing to the development of decision support systems.

Luther Gulick

  1. Proposed the concept of the POSDCORB acronym, which stands for Planning, Organizing, Staffing, Directing, Coordinating, Reporting, and Budgeting. This framework provided a systematic approach to managerial decision-making and organizational management.
  2. Emphasized the importance of division of work, clear communication channels, and effective coordination in decision-making processes.
  3. Advocated for a more scientific and rational approach to management, focusing on efficiency and effectiveness.

Lyndall Urwick

  1. Contributed to the development of the classical management theory, emphasizing principles of scientific management and administrative theory.
  2. Advocated for a systematic approach to decision-making, emphasizing the use of scientific methods and empirical evidence.
  3. Emphasized the importance of coordination, cooperation, and effective communication in decision-making processes.


Decision-Making Process

According to the decision theory, for the best organizational performance and efficiency, every manager should follow the following steps to make any decisions.

  1. Define the problem clearly:
    • Clearly articulate and understand the issue or challenge that requires a decision.
    • Identify the specific goals or objectives that need to be addressed through the decision-making process.
  2. Define decision premises:
    • Gather relevant information and data related to the problem or decision.
    • Identify the underlying assumptions, constraints, and factors that may influence the decision.
  3. Identify relevant alternatives:
    • Generate a range of possible options or alternatives that could potentially solve the problem or achieve the desired goals.
    • Consider both conventional and innovative solutions during this phase.
  4. Evaluate alternatives:
    • Analyze and assess each alternative based on predetermined criteria and decision premises.
    • Consider the potential risks, benefits, costs, and potential outcomes associated with each alternative.
  5. Select the best course of action:
    • Compare and contrast the evaluated alternatives and determine the most favorable option.
    • Consider the potential impacts on stakeholders, resource allocation, and alignment with organizational goals.
  6. Implement the selected alternative:
    • Develop an action plan outlining the steps required to put the chosen alternative into practice.
    • Allocate necessary resources, assign responsibilities, and establish a timeline for implementation.
  7. Evaluate and review the results:
    • Monitor and assess the outcomes of the implemented decision.
    • Compare the actual results with the expected outcomes and evaluate the effectiveness of the chosen alternative.
    • Identify lessons learned and make adjustments if necessary.

Study of Decision Processes

This theory facilitates the study of how administrative organizations make decisions. It allows researchers and practitioners to gain insights into decision-making processes, understands factors influencing choices, and identify areas for improvement, leading to enhanced decision-making practices within organizations.

Disadvantages of Decision Theory

Disadvantages of decision theory include:

Limited to Economic Rationale

The decision theory primarily focuses on economic factors and rational decision-making. It may overlook other important aspects such as ethical considerations, social impact, and long-term sustainability. This narrow focus can lead to decisions that prioritize short-term gains over broader organizational or societal well-being.

Limited Scope

The decision theory is specifically tailored to decision-making issues and may not provide a comprehensive view of management as a whole. It does not encompass all aspects of managerial responsibilities such as leadership, communication, and strategic planning. As a result, it may not fully address the complex and multifaceted nature of management practices.

Ambiguity in Decision Outcomes

In certain cases, it can be challenging to determine whether a decision marks the finalization or commencement of an action. The decision theory may not provide clear guidelines on how to handle such situations, potentially leading to ambiguity and confusion regarding the next steps to be taken.
