CONCEPT OF WORK STUDY
INTRODUCTION:
To survive in the current competitive and global environment, it is important for the
organization to continuously look at ways to improve efficiency and productivity. It
needs to discover a new, easy and cost-effective way of manufacturing or providing
services.
Work study and industrial engineering play important role in job simplification, job
design, job enrichment, value analysis/engineering, method analysis, operational
analysis, etc. Work study has been utilized by companies to job productivity. Industrial
engineering is the latest method employed to improve productivity. It deals with design,
enhancement and setting up of engineering systems encompassing plants, machinery,
workers, etc.
DEFINATION:
Work study is a means of enhancing the production efficiency or productivity of the
firm by elimination of waste and unnecessary operations. It is a technique to identify
non-value adding operations by investigation of all the factors affecting the job.
WORK STUDY:
Work Study forms the basis for work system design. The purpose of work design is to
identify the most effective means of achieving necessary functions. Work study aims at
improving the existing and proposed ways of doing work and establishing standard
times for work performance. Work design involves job design, work measurement and
the establishment of time standards and worker compensation. Work Study is
encompassed by two techniques -method study and work measurement or time study:
1. Method study is the systematic recording and critical examination of existing and
proposed ways of doing work, as a means of developing and applying easier and
methods and reducing costs.
2. Work measurement (or Time study) is the application of techniques designed to
establish the time for a qualified worker to carry out a specified job at a defined level
of performance.
There is a close link between method study and work measurement. Method study is
concerned with the reduction of the work content and establishing the one best way of
doing the job whereas work measurement is concerned with investigation and reduction
of any ineffective time associated with the job and establishing time standards for an
operation carried out as per the standard method.
The basic objective of production management is to manufacture the right quantity and
quality of goods at the predetermined time and pre-established cost. Work-study is tool
to achieve this objective. During the product design and process design, the methods of

manufacture are fixed and process planning is done using the standard times and
standard method. Methods analysis guide with respect to how the work is to be best
accomplished and time standards indicate how long it will take to complete the job.
IMPORTANCE OF WORK STUDY:
Work study is a means of enhancing the production efficiency (productivity) of the firm
by elimination of waste and unnecessary operations.
It is a technique to identify non-value adding operations by investigation of all the
factors affecting the job.
It is the only accurate and systematic procedure oriented technique to establish time
standards.
It is going to contribute to the profit as the savings will start immediately and continue
throughout the life of the product.
ADVANTAGES OF WORK STUDY:
It helps to achieve the smooth production flow with minimum interruptions.
It helps to reduce the cost of the product by eliminating waste and unnecessary
operations.
It creates better worker-management relations.
It assists in meeting the delivery commitment.
It helps in reducing rejections and scrap, and higher utilization of resources of the
organization.
It helps to achieve better working conditions.
It helps in designing better workplace layout.
It helps in improving upon the existing process or methods and helps in standardization
and simplification.
It helps in establishing the standard time for an operation or job which is used
in manpower planning and production planning.
STEPS INVOLVED IN WORK STUDY:
Select Job or Process to be studied;
Record all the details concerning job using various recording techniques;
Examine recorded facts critically by asking questions like who, what, when, why;
Develop most economical method;
Measure the amount of work involved and set standard time to do that job;
Define new method and standard time;
Install the new method as a standard practice;
Maintain new method as agreed standard.
