Question

question

for staff producing drain caps, a shift is eight hours, including one hour for breaks and lunch. demand can be met by completing 70 units per shift.

how many minutes is the takt time for the process?

6.85
6
6.9
7

Explanation:

Calculate available production time

To find the available production time, we subtract the non-productive time (breaks and lunch) from the total shift duration.
Total shift time is \(8\text{ hours}\).
Breaks and lunch take \(1\text{ hour}\).
Available production time in hours:

$$8\text{ hours} - 1\text{ hour} = 7\text{ hours}$$

Convert available time to minutes

Since the question asks for the takt time in minutes, we convert the available production time from hours to minutes.
Using the Six Sigma Metrics concept, we convert the time:

$$7\text{ hours} \times 60\text{ minutes/hour} = 420\text{ minutes}$$

Calculate the takt time

Takt time is defined as the available production time divided by the customer demand.
The required demand is \(70\text{ units}\).

$$\text{Takt Time} = \frac{\text{Available Production Time}}{\text{Customer Demand}}$$

$$\text{Takt Time} = \frac{420\text{ minutes}}{70\text{ units}} = 6\text{ minutes/unit}$$
