Productivity improvement is a critical success factor for the business profitability. Management may be able to
produce a larger quantity with better quality or higher value products with the same input resources by using the industrial
engineering tools and techniques. Manpower/ Labour productivity is the amount of work done by the group of workmen in
a given amount of time. Manpower productivity depends upon how effectively workmen are utilized. Manpower
productivity can be higher or lower depending on factors like availability of resources such as material, working tools,
availability of power, work efficiency, level of motivation, level of training, level of working condition (comfortable or
poor) etc. Manpower productivity can be measured in terms of hours or money.
Industrial Engineering is a science of decision-making which concerned with the design, improvement, and
installation of the integrated system of men, materials, and equipment. 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 result to be obtained from such a system.
Application of Industrial engineering tools and techniques helps in reducing production costs, increasing
efficiency, improving the quality of products and services, ensuring worker health and safety and protecting the
environment. Work study is the systematic examination of the methods of carrying on activities so as to improve the
effective use of resources and to set up standards of performance for the activities being carried out by reducing
unnecessary or excess work, whereas Industrial ergonomics aims at achieving an optimal fitting of the work environment
and job activities to the worker.
5’S is a Japanese Philosophy of Workplace organization techniques which work on principles of Seiri (tidiness),
Seiton (orderliness), Seiso (cleanliness), Seiketsu (standardization) & Shitsuke (discipline). Similarly Lean principles helps
for elimination of 7-Waste in the processes namely transportation, inventory, motion, waiting, over processing,
overproduction, and defects.
At Hindalco Industries Ltd., Mouda, Quality of Chock services and delay in supply was resulting in performance
losses of Mill-M4 machine causing downtime. Initial workplace audit was conducted based on the 5’S, Ergonomic aspects,
Engineering tools and practices, workplace layout, Material flow etc. including Work Study to understand activity
sequence and the activity time which will give the fare idea about existing work patterns, Working spaces, material &
tools, material flow, ergonomics, workplace layout design, tooling, maintenance practices, material storage & handling
practices etc. and proposed the best workplace design with the suitable best industry practices and improve manpower
productivity using Industrial Engineering tools.

of application of Industrial Engineering tools and techniques in productivity improvement which are to be considered while
designing the workstation.
In order to work efficiently and to manufacture good quality products and to increase productivity, the workplace
wants to be designed by considering ergonomic principles (M. Muhundhan, 2013).
Marksberry, P., & Parsley, D. (2011), Toyota encourages an older version of IE, namely standardization.
Broberg, O. (2010), Workspace design: a case study applying participatory design principles of healthy
workplaces in an industrial setting talks about the industrial manufacturer case showed how the WSD concept might
contribute to an engineering design process.
Mr. Sujay Biswas, Dr. Abhijit Chakraborty, Mrs. Nabanita Bhowmik (2015), The manufacturing unit by doing
work study can make effective utilization of resources. Work study which comprises of method study and work
measurement will fulfill these requirements. By method study, one can determine the most effective method of performing
the job, the most logical layout for manufacturing facilities, uninterrupted flow of material throughout the organization;
will help to complete the job in least possible time and at optimum cost. Work measurement on the other hand determines
the time required by an operator to complete the operation of job for the standard method at the defined level of
performance.
Thus, work-study is the most effective tool to enhance productivity because of the fact that it is a straight-forward
way of increasing productive efficiency of the organization and considers all the factors influencing productivity.
