Synthesis
In many industries the work done is of a repetitive nature that is the product is produced in large number or in batches or varying sizes at irregular intervals. Even when the products are made only once it is done by operations which are frequently used in the factory. In such cases it is not necessary to carry out time study techniques. Synthetic techniques are used where standard time is computed by adding various elements times which constitute the work standard data is made available for most of the known element operations such as preparatory, setting manipulating removing clearing tool positioning holding and tightening. The data should be stored in a library in such a manner for easy reference when required for estimating scheduling or any other purpose. These standards cannot be transferred to other factories as they refer to the particular condition prevailing in a specific worker shop at a given factory.
Advantages of Synthesis Method
1. Reduction in the number of time studies and consequently in the cost of running the time study department.
2. Reduction in time required to issue a time standard for a job.
3. Consistency in the time standards.
