Answer :
The Takt time calculation reveals that the firm's Takt time is 0.261 hours per unit, corresponding to Option d.
In determining the Takt time, we evaluate the company's manufacturing capacity against the demand from customers. Initially, we convert the monthly customer demand of 188,000 units into a weekly equivalent by multiplying it by 12, as there are roughly 4 weeks in a month.
Thus, the weekly customer demand amounts to approximately 47,000 units. Subsequently, by dividing the available manufacturing capacity of 13,500 hours per week by the weekly customer demand of 47,000 units, we derive the Takt time. This computation yields a Takt time of approximately 0.287 hours per unit.
The given statement "The Takt time for this firm is 0.261 hours/unit" is false because the accurate calculation yields a Takt time of approximately 0.287 hours per unit, corresponding to Option d. Therefore, the correct Takt time for this firm is indeed 0.261 hours per unit.
Correct option: d
