A capsul to explaine a part of industrial engineering,time study, one of the powerful tools that used to adapt the Rhythm inside the value stream, to create an eye on the process and to improve & control the process cost.

3. • Taiichi Ohno (大野耐一 Ōno Taiichi, February 29,
1912 – May 28, 1990) was a Japanese industrial
engineer and businessman. He is considered to be
the father of the Toyota Production System, which
became Lean Manufacturing in the U.S.
• He moved to the Toyota motor company in 1943
where he worked as a shop-floor supervisor in the
engine manufacturing shop of the plant, and
gradually rose through the ranks to become an
executive.

Path of Excellence (4P Model)

5. Lean Manufacturing
• The core idea of lean is to maximize customer value
while minimizing waste.
• Optimizing the flow of products and services through
entire value stream that flow horizontally across
technologies, assets and departments to customers.
• Eliminating waste along entire value streams instead
of isolated points creates processes that need less
human effort, less space, less capital, less cost , less
defects and less lead time.

6. Industrial Engineering
• Industrial engineering is a branch of engineering which deals with the
optimization of complex processes, systems, or organizations.
• Industrial engineering is concerned with the design, improvement, and
installation of integrated systems of men, materials, and equipment.
Industrial engineering draws upon specialized knowledge and skill 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 from such systems

7. Industrial Engineering
Industrial engineering is the branch of engineering that involves figuring out
how to make or do things better. Industrial engineers are concerned with
reducing production costs, increasing efficiency, improving the quality of
products and services, ensuring worker health and safety (Ergonomics),
protecting the environment and complying with government regulations (HSE).

Work
Study
The systematic examination of
activities in order to improve the
effective use of human and other
material resources.
The application of
techniques designed to
establish the time for a
qualified worker to carry
out a task at a defined
rate of working.
The systematic recording
and critical examination
of ways of doing things in
order to make
improvements

10. • Select (the work to be studied)
• Record (all relevant
information about that work)
• Examine (the recorded
information)
• Develop (an improved way of
doing things)
• Install (the new method as
standard practice)
• Maintain (the new standard
proactive)
•Work Sampling
•Time Study

11. Observation, recording and rating of human work to
establish the times required by a qualified worker to
perform specified work under stated conditions at a
defined rate of working.

To Rate
To assess the workers rate of working relative to the observer's
concept of the rate corresponding to standard rating.

17. MAKING A TIME STUDY
Time Study
• communicate with all persons who are likely to be involved such as Managers,
Supervisors, Shop Stewards and Operators. This communication is essential if the
Work Study Engineer is to gain full co-operation from others.
• Ensure that conditions on the job being studied are suitable Ensure that Labor is
properly trained, conditions on the job being studied are suitable , Machinery
and equipment is adequately maintained, … etc.
• Obtain all the necessary details about the job, the operator, machine and
surroundings, together with a complete description of the method.

18. Time Study
MAKING A TIME STUDY
• Make a number of Time Study observations.
• Convert the observed times to "basic times".
• Determine the Relaxation Allowance for each element of the operation.
• Determine the frequency or number of times each operation occurs in each
work cycle.
• Compile the Basic Work Content for the job, unit or batch. This is obtained by
multiplying the Basic Work Content of each element by the frequency and then
totaling the time spent.
