__________ is variation in a production process that can be traced to specific causes.
A product is currently made in a process-focused shop, where fixed costs are $8,000 per
year and variable cost is $40 per unit. The firm currently sells 200 units of the product
at $200 per unit. A manager is considering a repetitive focus to lower costs (and lower
prices, thus raising demand). The costs of this proposed shop are fixed costs = $24,000
per year and variable costs = $10 per unit. If a price of $80 will allow 400 units to be
sold, what profit (or loss) can this proposed new process expect? Do you anticipate that
the manager will want to change the process? Explain.
