• Method study or Motion study is one of principal techniques by which work content in the product manufacture or process could be decreased.
• It is a systematic method of investigating and critically examining the existing methods, to develop the improved ones.
• Method study is, then, a technique to reduce the work content mainly by eliminating unnecessary movements by workers and/or materials and/or equipments.
• However, even after that, there could be substantial unnecessary time taken for the process because of lack of management control and/or inaction of worker
Introduction
11
• Work measurement or time study is the application of techniques designed to establish the time for a qualified worker to carry out specified jobs at a defined level of performance.
• We have seen how total time to manufacture a product is increased by:
adding undesirable features to product, bad operation of the processes, and ineffective time added because of worker and
management.
• All this leads to decreased productivity.
Introduction
12
• The design and measurement of work and the problem solving process are fundamental to modern industrial organization.
• Why use it ? : - Productivity - Improving equipment utilization - Conserving materials and energy - Reducing human effort - Advancing the goals of the organization
on many fronts
Introduction
13
• A person working with motion and time study will study an individual job or series of jobs to learn the details of what works and make details.
• Changes may be small, but improvements must be made continually to keep the company competitive.
• Quality and price are the most important considerations for staying competitive
• Motion and time study concentrate on reducing cost but must never lost sight on quality

1. Develop the best work method2. Develop motion consciousness on the part of all
employees3. Develop economical and efficient tools, fixtures,
and production aids.4. Assist in the selection of new machine and
equipment5. Train new employees in the preferred method6. Reduce effort and cost
