- 2. OBJECTIVE OF THE PROJECT WORK TO IMPLEMENT WORKSTUDY CHARTS TO OBTAIN MAXIMUM UTILIZATION OF THE RESOURCES(MAN, MACHINE AND MATERIALS) AND TO OPTIMIZE WORKPLACE BY CHANGING THE PLANT LAYOUT AND WORKSTATION, USING THE PROCESS CHARTS.
- 3. ROLE OF INDUSTRIAL ENGINEERING DEPARTMENT IN APPAREL INDUSTRY. Importance of Industrial Engineering (IE) tools that can be used to improve upon the productivity of their factories and thus enhance the profits ! Very few companies have been operating with a full-fledged industrial engineering department and even those which boast of an Industrial Engineering Department (IED) in their factories are not allowing ample freedom and scope to function to its full capabilities. The role of IED is important for the garment industry for the following two reasons: It’s a highly labor-intensive industry. Effective planning is emerging as one of the key factors for the garment manufacturing industry.

- 19. WORKSTATION DESIGN The work station design affects the production rate, efficiency and the accuracy with which an operation can be performed. A work station not only needs space for the workers and the machine, there are plenty of other items which also need accommodation. Space requirements and a few more factors governing a good work station design are described below: Space requirements Consideration of the space required, for the movement of material handling equipments. Easy access to safety stops in case of emergency. Easy access to machine for inspection, lubrication, maintenance and repair. Convenience of making foundations and machine installations. Aisle space between one machine and the next. Appropriate ventilating, lighting and safety arrangements.

- 24. WORK STUDY
- 25. IMPORTANCE OF WORK STUDY Improving the planning of work. Improving Methods of production. Effective Worker Selection Processes. Improving Worker Effectiveness. Providing Workers with Adequate Training. Improving Worker Morale. Rewarding worker Morale. Improving worker attendance levels. Reducing worker labor turnover. Effective Communications.
- 26. IMPLEMENTING WORK STUDY CHARTS IN APPAREL MANUFACTURING Objective : To record the movements of man, machine & materials in a layout, study the distance covered, time involved, interaction between them, identify the area for improvement, and suggest a better way to overcome these problems.
- 27. WORK STUDY- DEFINITION Work study is a generic term for those techniques, particularly method study& work measurement, which are used in the examination of human work in all its context, & which lead systematically to all the factors which affect the efficiency & economy of the situation being reviewed, in order to effect improvement.
