Work measurement represents the techniques for establishing standard time for an activity by a qualified worker at a specified level of performance. Standard time is the time taken by an average experienced and qualified worker to accomplish an activity with delays beyond the control of the worker. Work measurement endeavors to remove ineffective times. Therefore, work measurement also evaluates a worker’s performance by comparing the performance of the worker with the standard performance. Work measurement also helps to determine the capacity required for a given level of work and machinery. Moreover, work measurement compares different work methods in terms of costs.

Standard-cost systems are based on the assumption that there is a certain amount of material and a given amount of labor that go into the manufacture of a component. Implementation of this system involves advance preparation of standard rates for materials, labor, and expenses. Standard time is defined as the total time in which a job should be completed at standard performance of a qualified worker. Information on standard times and costs can be collected by the company for their particular processes or found in the literature where a large amount of data for special or general work has been published.

Industrial engineers develop solutions to improve efficiencies in production by reducing waste. They use principles of Six Sigma and lean manufacturing to optimize production and manufacturing processes. Industrial engineers are also involved in monitoring the health and safety of workers in manufacturing and other industries. Typical activities performed by industrial engineers may include the following: Develop innovative methods to maximize efficiency in the production processes.Review engineering drawings and specifications to develop process flows, methods, and production schedules to reduce cycle time and production costs.Develop and implement quality management procedures to improve product quality and reliability.Address issues related to production systems and perform time studies to determine standard time required to perform tasks.Coordinate with design, manufacturing, and production personnel to eliminate waste.Review and improve equipment and systems, moving toward ergonomic designs.Perform simulation of production systems to improve efficiency and reduce cost.Coordinate with suppliers as well as internal and external customers to develop a robust supply chain management system.

Time study is nothing but finding out the time taken for the activities. The time study will give us the standard time which is considered as a base for the project. The standard time is the reasonable time that an operator requires to perform a given task. Standard time also includes all allowances given to the operator. In this article all the time study had been taken by stopwatch. Time study of all 10 machines, rework, inspection and preparation had been taken. This time study helps in evaluating cycle time for each process and also helps in constructing value stream map. Time study provides the basis for calculating bottleneck operations.

Standard time is the time needed to complete a work cycle carried out according to the normal working method and speed with the consideration of the adjustment factor plus the allowance for personal and other unexpected purposes. The formula is used as follows:
