MANAGEMENT THEORIES


1            Scientific Management
  The systematic study of the relationships between people and tasks for the purpose of redesigning the work process for higher efficiency.
          Defined by Frederick Taylor in the late 1800’s to replace informal rule of thumb knowledge.
          Taylor sought to reduce the time a worker spent on each task by optimizing the way the task was done.
         Four Principles of Scientific Management
          Principles to increase efficiency:
1.   Study the ways jobs are performed now and determine new ways to do them.
          Gather detailed time and motion information.
          Try different methods to see which is best.
2.   Codify the new methods into rules.
          Teach to all workers the new method.
3.   Select workers whose skills match the rules.
4.   Establish fair levels of performance and pay a premium for higher performance.
     >   Workers should benefit from higher out
       Problems with Scientific Management
          Managers frequently implemented only the increased output side of Taylor’s plan.
  Workers did not share in the increased output.
          Specialized jobs became very boring, dull.
  Workers ended up distrusting the Scientific Management method.
          Workers could purposely “under-perform.”
  Management responded with increased use of machines and conveyors belts.
         Frank and Lillian Gilbreth
          Refined Taylor’s work and made many improvements to the methodologies of time and motion studies.
  Time and motion studies
          Breaking up each job action into its components.
          Finding better ways to perform the action.
          Reorganizing each job action to be more efficient.
                                  Administrative Management Theory
    The study of how to create an organizational structure that leads to high efficiency and effectiveness.
          Max Weber
    Developed the concept of bureaucracy as a formal system of organization and administration designed to ensure efficiency and effectiveness.
      Weber’s Five Principles of Bureaucracy
          Authority is the power to hold people accountable for their actions.
          Positions in the firm should be held based on performance, not social contacts.
          Position duties are clearly identified so that people know what is expected of them.
          Lines of authority should be clearly identified such that workers know who reports to who.
          Rules, standard operating procedures (SOPs), and norms guide the firm’s operations.
            Behavioral Management Theory
    The study of how managers should behave to motivate employees and encourage them to perform      at high levels and be committed to the achievement of organizational goals.
   Focuses on the way a manager should personally manage to motivate employees.
          Mary Parker Follett
   An influential leader in early managerial theory
   Held a horizontal view of power and authority in organizations
          Suggested workers help in analyzing their jobs for improvements—the worker knows the best way to improve the job.
          If workers have relevant knowledge of the task, then they should control the task.
       Theory X and Theory Y
          Douglas McGregor proposed the two different sets of assumptions about workers.
      Theory X assumes the average worker is lazy, dislikes work and will do as little as possible.
          Managers must closely supervise and control through reward and punishment.
      Theory Y assumes workers are not lazy, want to do a good job and the job itself will determine if the worker likes the work.
          Managers should allow workers greater latitude, and create an organization to stimulate the workers.
            Management Science Theory
          An approach to management that uses rigorous quantitative techniques to maximize the use of organizational resources.
 Quantitative management—utilizes linear programming, modeling, simulation systems.
  Operations management—techniques to analyze all aspects of the production system.
  Total Quality Management (TQM)—focuses on improving quality throughout an organization.
  Management Information Systems (MIS)—provides information about the organization.
             Organizational Environment Theory
          The set of forces and conditions that operate beyond an organization’s boundaries but affect a manager’s ability to acquire and utilize resources
        Two-Systems View
          Open System
     A system that takes resources for its external environment and converts them into goods and services that are then sent back to that environment for purchase by customers.
  Inputs: the acquisition of external resources.
  Conversion: the processing of inputs into goods and services.
  Output: the release of finished goods into the environment.
          Closed system
  A system that is self-contained and thus not affected by changes occurring in its external environment.
  Often undergoes entropy and loses its ability to control itself, and fails.
          Synergy
  Performance that results when individuals and departments coordinate their actions
          Performance gains of the whole surpass the sum of the performance of the individual components.
             Contingency Theory
  The idea that the organizational structures and control systems manager choose depend on—are contingent on—characteristics of the external environment in which the organization operates.
  Assumes there is no one best way to manage.
          The environment impacts the firm and managers must be flexible to react to environmental changes.
  In rapidly changing organizational environments, managers must find ways to coordinate different departments to respond quickly and effectively.

         Mechanistic and Organic Structures
              Mechanistic Structure
  Authority is centralized at the top. (Theory X)
  Employees are closely monitored and managed.
  Can be very efficient in a stable environment.
             Organic structure
  Authority is decentralized throughout the organization. (Theory Y)
  Tasks and roles are left ambiguous to encourage employees to react quickly to changing environment.
