Management Science Theory: Definition, Branches, Contributions, and Limitations

What is Management Science Theory?

Management science theory is also called the mathematical, quantitative, and operational research approach. Management science theory emphasizes on applications of mathematics and statistics for decision-making and solving management problems.

This theory focuses on solving technical problems rather than human relations problems. And computer programs are used to analyze the problems. This theory developed during the Second World War to solve military problems by the UK and USA.

After the end of the war, people started using this technique for industrial problems solving. The management science approach is primarily concerned with decision-making. Linear programming, game theory, sampling theory, probability theory, simulations, etc are the techniques that managers use to solve resource allocation problems.

Joel Dean and PMS Blackett are the main contributors to this management science approach. This theory uses knowledge from different areas to solve problems. Thus this is mostly useful for solving complex management problems and developing good operational research.

Branches of Management Science Theory

Quantitative management, operation management, and information management systems are three interconnected branches of management science theory that aid managers in making informed decisions, optimizing resources, and enhancing overall organizational efficiency.

Quantitative Management

It employs mathematical techniques like linear programming, modeling, and sampling theory to analyze available data. By harnessing these methods, managers can gain valuable insights, enabling them to make better decisions and drive organizational success. This approach relies on the power of numbers and data analysis to provide a systematic framework for decision-making.

Operation Management

It focuses on the effective utilization of organizational resources and production systems. Its primary goal is to enhance the quality of goods and services offered by the business firm. Through the application of operational research techniques, managers can identify bottlenecks, streamline processes, and maximize efficiency. This branch emphasizes the importance of optimizing production systems to achieve desired outcomes.

Information Management System

Information management systems (MISs) are computerized systems that store and organize data used by business organizations. They enable managers to access and utilize information effectively when needed, facilitating informed decision-making.

By designing information systems that capture and analyze relevant data about internal and external events, managers can gain valuable insights into the organization’s performance and make strategic choices accordingly.

Importance of Management Science Approach To Business

The management science theory plays a crucial role in small businesses as it enables owners and managers to design effective measures for evaluating processes and decisions. By utilizing basic computer applications and predictive analysis, they can address management issues at various organizational levels.

Embracing the quantitative approach empowers managers to plan, organize, lead, and control operations, resulting in increased production, industrial harmony, and the benefits of specialization. Furthermore, this approach prioritizes maintaining clean and safe work environments, fostering motivated employees, and improving working conditions.

The management science theory’s importance lies in its ability to optimize business operations, enhance decision-making, and create a conducive work environment, all contributing to the overall success and growth of a business.

Contributions and Limitations of Management Science Theory


The following are the main contributions of the management science theory of management.

  • It encourages in use of knowledge from different disciplines.
  • Complex relations among variables can be expressed more effectively.
  • Decisions can be more precise with the use of a mathematical approach.
  • It emphasizes on replacement of intuition and hunch with factual data and logical analysis in the decision-making process.


  • It ignores the human relations aspects compared to human relations theory.
  • All the assumptions cannot be realistic.
  • Data and facts may not be available all the time.
