The standard time
Standard time is the total time in which a job should be
completed at standard performance
Standard time for a simple manual job.
The standard time is expressed in standard minutes or
standard hours
Why Measure the work
To determine the facts about how an individual operation or
group of operations are performed within the workplace.
- Assess the effectiveness of the people & machinery employed
Traditionally Time Study has been utilized to establish time
standards.
- Weakness of this system are the accuracy of an individual’s Performance Rating
To overcome this problem a considerable number of Predetermined
Motion Time Systems (PMTS) were produced during Second World War & among
these Methods-Time Measurement (MTM) has become very widely used throughout the
world.
No Measurement = No Management
Inaccurate Measurement = Ineffective Management
Accurate Measurement = Effective Management
Major considerations
- Restrict the number of jobs
- Reliability of the data
- Nature of material, thickness & weight
- Source of the time data
Developing the standard data
- Decide on coverage (similar elements, method)
- Break the jobs into elements (lifting, positioning, walking, placing)
- Read through MTM-2.
- Determine the factors (Major: Distance covered; Minor: Temperature, Humidity)
Computerized System of Developing Standard Data
