My take on this question :
Shikari (S) : OT(Overtime) is bad, expensive, quality of work declines
Jackson (J) : Alt(Alternative increasing basic capacity) has the same disadvantages
We need to find an option that shows us either of the below :
1. OT> Alt
2. OT<Alt
Shiraki: Overtime work is a bad response to situations where orders from clients exceed normal production capacity: overtime is expensive, and the quality of work declines as the proportion of overtime work increases.
Jackson: The alternative-increasing basic capacity-has the same disadvantages, because inexperienced staff must be hired and experienced production staff must be reassigned to train newly hired workers.
Assuming that both of the positions above are correct, clarification of which of the following issues would be most important in deciding which of the two alternatives to choose?
A. Is the elevated level of orders likely to be a chronic rather than a temporary condition?
If this is a temporary condition, investment in Alt does not make sense.
Correct.
B. Has overtime work been resorted to in the past when orders received have gone beyond normal capacity?
Even if this was resorted to in the past, what is the guarantee that OT will be successful now?
C. Will suppliers of needed raw materials, fuels, etc., be able to step up deliveries to sustain a higher-than-normal level of production?
Third party factor- should not be considered
D. Would it be possible to increase the proportion of the company's work that is carried out off-site by subcontractors?
In a way, we can eliminate the need both for OT and Alt in this case.
E. Is labor-saving machinery being used optimally in all phases of production?
Third party factor- should not be considered
