Introduction
• Method study or Motion study is one of principal
techniques by which work content in the product manufacture or process the improved ones.
could be decreased .
• It is a systematic method of investigating and
critically examining the existing methods, to develop
• 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
• 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 product is increased by: .
• We have seen how total time to manufacture a
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
• 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 12
Introduction
• 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 13
