Improve productivity By Method Study:
- Reduce the Number of motions and grasps / Make the best use of both hands
- Reduce the distances moved - Keep things as close as possible
- Reduce precision - Use edge guides, folders etc.
- Reduce eye-shifts - Kinesthetic sense
- Simplify grasps - Arranging workstation layout
- Toss dispose rather than place dispose - Waterfall arrangement, use gravity
- Encourage rhythm
Process of Method Study:
- Select the work to be studied
- Define the objective
- Record relevant information and data
- Examine the information and data collected
- Develop the improved method
- Install the improved method
- Maintain the improved method
Improve productivity By Time Study:
Costing: By knowing how long it takes to perform a job, the total time and cost for manufacturing a product can be determined. Determine sales price.
Manpower Planning: By knowing how many units one person can produce it can be determined how many people are needed to produce a given volume.
Machine Requirements: The number of machines required can be determined by knowing the output from one machine.
Production Planning: Time study enables us to measure the capacity of a plant to produce. Decision as to how much volume to load into a plant can be made
Process of Time Study:
Industrial engineers use decimal minute stopwatches which read in:
1 minute = 100 centiminutes

1 |
Observe the job and break it into Elements. |
Elements |
2 |
Rate each element by comparing with the accepted standard |
Element Rating |
