Scientific Management


 • Measurement Plus Control
           Defines a “Fair Day’s Work”
 • Methods Control
 • Dr. Taylor
           “The greatest production results when each worker is
            given a definite task to be performed in a definite
            time in a definite manner.”

Scientific Management


Scientific management is based upon measurement, planning and control. Work
measurement is the common denominator because it produces the necessary
data for planning and the standards for control.

Industrial Engineering


 • “Industrial Engineering is concerned with the
   design, improvement, and installation of
   integrated systems of people, materials,
   equipment, and energy. It draws upon
   specialized knowledge and skills in the
   mathematical, physical, and social sciences,
   together with the principles and methods of
   engineering analysis and design, to specify,
   predict, and evaluate the results to be
   obtained by such systems.”
   Institute of Industrial Engineers, 1955, 1975

Methods Engineering


 • “Methods Engineering is the technique that subjects
   each operation of a given piece of work to close analysis
   in order to eliminate every unnecessary operation and
   in order to approach the quickest and best method of
   performing each operation; it includes the
   standardization of equipment, methods, and working
   conditions; it trains the operator to follow the standard
   method; when all this has been done, and not before, it
   determines by accurate measurement the number of
   standard hours in which an operator working with
   standard performance can do the job; finally, it usually,
   although not necessarily, devises a plan for
   compensation labor which encourages the operator to
   attain or surpass standard performance.”
      Dr. Harold B. Maynard 1939

Predetermined Time Systems



 Substantial impulse to predetermined time systems was
 given by F. W. Taylor (1865-1915) and particularly by F.
 B. Gilbreth (1868-1924).
 Gilbreth realized that the time for two operators to
 execute an operation with
         • the same training (skill)
         • the same qualification (suitability)
         • the same performance (effort)
 within reasonable limits, depend only on the
 method.

What is MTM?


 • Methods-Time Measurement is a
   procedure which analyzes any manual
   operation or method into the basic
   motions required to perform it and
   assigns to each motion a
   predetermined time standard which
   is determined by the nature of the
   motion and the conditions under which
   it is made.

Methods-Time


 • The specific method must be chosen or
   established before any meaningful time
   can be assigned.




 January 2005     The MTM-1 System          13
Procedure


 • Definite analysis steps which must be
   made following system rules.

Manual Operation


 • Evaluates the normal operations
   performed by people, giving a time as
   controlled by human energy.
