It is the “time” required to produce a product at a work station
Time Standard
It is the “time” required to produce a product at a work station with the following three conditions:
- Qualified, well-trained operator
- Working at a normal pace
- Doing a specific task
- This is required.
- Experience is usually what makes a qualified, well-trained operator, and time on the job is our best indication of experience.
- A good rule of thumb is to start with a qualified, fully trained person and to give that person two weeks on the job prior to the time study.
Qualified, Well-trained Operator
*Only one time standard can be used for each job, even though individual differences of operators cause different results.
*A normal pace is comfortable for most people.
Normal Pace
- Detailed description of what must be accomplished.
- The description of task must include:
* Prescribed work method
* Material specifications
* Tools and equipments being used
* Positions of incoming and outgoing material
* Additional requirements like safety, quality, housekeeping, and maintenance tasks.
Specific Task
Time standard
1min/pc x 1hr/60 min = 1hr/60pcs
- The time standard is only good for this one set of specific conditions. If anything changes, the time standard must change.
- If a job takes 1.000 standard minutes to produce, we can produce 60 pcs per hour, and it will take 0.01667 hrs to make one unit or 16.67 hrs to make 1000 units.
1min/pc x 1hr/60 min = 1hr/60pcs
How to calculate?
- Pieces per hour is calculated by dividing the time standard minutes into 60 minutes per hour.
- Hours per piece is calculated by multiplying the standard time per piece by 1 hour/60min.
- Hours per 1000 pieces is calculated by multiplying the hours per piece by 1000 pieces
