Which of the following would tend to reduce effective capacity? a greater variety in the product line b suppliers that provide more reliable delivery performance c reduced changeover times d improved production quality e more employee cross-training

a. a greater variety in the product line

Explanation:

"Effective capacity" refers to the maximum possible output in relation to a given product variety, difficulties with schedules, quality factors and so on.

Letter a, "greater variety in the product line," will reduce effective capacity because the more varieties of goods there are, the more complex the process in producing the output will be. This will then lower the output being produced compared to a smaller variety of goods.

Letter b, "suppliers that provide more reliable delivery performance" will increase the effective capacity because the delivery of items or products are on time, so this will result to increase output.

Letter c, "reduce changeover times" will increase the effective capacity. "Change over time" refers to the time it takes from the last part of the product run to the first part of the product run. If time of the cycle will be shortened, then, it can produce more output.

Letter d, "improved production quality" will increase the effective capacity. This means that quality improvement will prevent products from being returned, thereby speeding the process.

Letter e, "more employee cross-training" will increase the effective capacity. Employees will be able to do many kinds of work, thereby hastening the process and producing more outputs.
