- 1. Method Study Comprehensive LectureSlides Prepared by: Rajkeerthi E Department of Manufacturing / Industrial Engineering
- 2. Introduction to MethodStudy • Method study is a systematic and scientific approach used to analyze work processes and improve productivity • It involves recording existing methods, critically examining them, and developing better and more efficient ways of performing tasks • This technique is widely used in industrial engineering and operations management to
- 3. Definition of MethodStudy • Method study can be defined as the systematic recording and critical examination of existing and proposed methods of doing work • Its main objective is to develop and apply easier and more effective methods, reduce unnecessary motions, and ensure efficient utilization of manpower, machines, and materials in industries.
- 4. Objectives of MethodStudy • The main objectives of method study include increasing productivity, reducing operational costs, improving quality of products, and enhancing safety in the workplace • It also aims to standardize work procedures, minimize worker fatigue, and ensure better utilization of equipment and resources in production systems.
- 5. Importance of MethodStudy • Method study plays a crucial role in improving organizational efficiency by identifying inefficient operations and eliminating waste • It helps in improving plant layout, reducing material handling, and ensuring smooth workflow • Organizations use method study to achieve higher profitability and better competitiveness in the market.
- 6. Work Study andMethod Study Relationship • Work study consists of two main techniques: method study and work measurement • While method study focuses on improving work methods, work measurement determines the time required to perform a task • Together, they help in establishing standard times and efficient production processes.
- 7. Steps in MethodStudy • The method study procedure includes six main steps: selecting the job or process, recording the existing method, examining the recorded facts, developing an improved method, installing the new method, and maintaining the method • Each step is important for ensuring systematic improvement and continuous development.
- 8. Selection of Workfor Study • The selection of work for method study is based on factors such as high production cost, bottleneck operations, repetitive tasks, and safety-critical operations • Jobs that have frequent delays, high labor content, or quality issues are also selected for study to improve efficiency.
- 9. Recording Techniques inMethod Study • Recording techniques are used to document existing methods in a systematic manner • Common techniques include process charts, flow process charts, flow diagrams, string diagrams, and two-hand process charts • These tools help in visualizing work processes and identifying inefficiencies.
- 10. Process Chart Symbols •Standard symbols are used in process charts to represent different activities such as operation, inspection, transportation, delay, and storage • These symbols help in simplifying complex processes and making it easier to analyze and improve the workflow in industrial systems.
- 11. Flow Process Chart •A flow process chart provides a detailed record of all operations, inspections, transports, delays, and storage activities in a process • It is useful for analyzing the sequence of operations and identifying unnecessary steps that can be eliminated or simplified.
- 12. Flow Diagram andString Diagram • Flow diagrams show the movement of materials or workers on a layout, while string diagrams measure the distance traveled using a string • These diagrams are helpful in improving plant layout, reducing material handling costs, and minimizing worker movement in industrial environments.
- 13. Critical Examination Technique •Critical examination involves questioning every aspect of a job using questions such as why, where, when, who, and how • This technique helps in identifying unnecessary activities, improving sequence of operations, and developing more efficient work methods.
- 14. Principles of MotionEconomy • Principles of motion economy aim to reduce unnecessary motions and improve worker efficiency • They include using both hands effectively, minimizing body movements, arranging tools and materials conveniently, and using mechanical aids to reduce manual effort and fatigue.
- 15. Development of ImprovedMethod • After critical examination, an improved method is developed by eliminating unnecessary steps, combining operations, rearranging sequences, and simplifying work elements • The new method should be practical, economical, and acceptable to workers and management.
- 16. Installation of NewMethod • Installation involves implementing the improved method in the workplace • It includes training workers, modifying tools and equipment, updating layouts, and providing clear instructions • Proper supervision is necessary to ensure successful adoption of the new method.
- 17. Maintenance of Method •Maintenance ensures that the improved method continues to be followed • It includes periodic reviews, audits, worker feedback, and continuous improvement initiatives • Standard operating procedures should be updated regularly to reflect changes in processes and technology.
- 18. Advantages of MethodStudy • Method study provides several advantages such as increased productivity, reduced operational costs, improved product quality, better utilization of resources, and enhanced worker safety • It also improves morale by reducing fatigue and making work easier and more systematic.
- 19. Limitations of MethodStudy • Despite its benefits, method study has some limitations such as resistance from workers, high initial cost of implementation, and the need for skilled analysts • It may also require significant time and effort to analyze complex processes in large organizations.
- 20. Applications of MethodStudy • Method study is widely applied in manufacturing industries, service organizations, hospitals, offices, and construction projects • It helps in improving production systems, service delivery processes, and administrative procedures to achieve higher efficiency and effectiveness.
- 21. Conclusion • Method studyis a powerful tool in industrial engineering that helps organizations achieve continuous improvement • By systematically analyzing and improving work methods, organizations can reduce waste, increase productivity, and achieve sustainable growth in a competitive industrial environment.
