Davison Electronics four manufacturing plants. Each model has its lowest possible production cost when produced at Plant 1. However, Plant 1 does not have the capacity to handle the total production of all three models. As a result, at least some of the production must be routed to the other manufacturing plants. The following table shows the minimum production requirements for next month, the plant capacities in units per month, and the production cost per unit at each plant: Model Production Cost per Unit Minimum Production Requirements Plant 1 Plant 2 Plant 3 Plant 4 A $25 $28 $37 $34 48,000 B $26 $35 $36 $41 75,000 C $20 $31 $26 $23 60,000 Production Capacity 65,000 50,000 32,000 43,000 Davison’s objective is to determine the cost-minimizing production planarrow_forwardAnecdotally, entrepreneurs frequently encounter two critical dilemmas in managing human resources: the timing of hiring and the decision regarding hiring a generalist versus a specialist for their growing venture. Deciding when to expand a team is crucial, as premature hiring (i.e., hiring too soon) can strain resources, while delayed hiring (i.e., hiring too late) might hinder growth opportunities. Moreover, the choice between hiring a generalist or a specialist depends on the specific needs and stage of the venture, with each option presenting distinct advantages and challenges. To address these issues, a management scholar seeks to identify the factors shaping the hiring cycle throughout the entrepreneurial journey and to understand the criteria for choosing between generalists and specialists at various stages of a venture. The scholar has assembled a sample of 20 experienced South African entrepreneurs who have encountered both failure and success in the financial technology…arrow_forward
