Total Labour cost = $1,800,000 There is a lot of hiring of new workers involved which comes with a cost of $284.50 per new worker so the hiring cost is going to be pretty high. As it is the labour cost in case of demand chase is more than that in level production in addition to which there is a high hiring cost due to which it is not feasible to go with the demand chase strategy. Conclusion Having performed the numerical analysis, we find that there is a significant cost involved in the demand chase strategy with the hiring of new workers. Though comparatively, the level production strategy has a lower cost associated with it but even in that case the labour usage is pretty less. Therefore, we suggest that it is best to use a hybrid strategy wherein we use the level production strategy until July and then resort to the demand chase strategy after July. This way we would be able to get the benefits of both the strategies. ?? ?? ?? ?? ...read more.
