Answer:
a. a greater variety in the product line
Explanation:
"Effective capacity" refers to the <em>maximum possible output </em>in relation to a <em>given product variety, difficulties with schedules, quality factors and so on. </em>
Letter a, <u>"greater variety in the product line,"</u> will reduce effective capacity because <em>the more varieties of goods there are</em>, <em>the more complex </em>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, <u>"suppliers that provide more reliable delivery performance"</u> will <em>increase the effective capacity </em>because the delivery of items or products are on time, so this will result to increase output.
Letter c,<u> "reduce changeover times"</u> will <em>increase the effective capacity.</em> <em>"Change over time"</em> 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,<em> </em><u><em>"improved production quality" </em></u>will<em> increase the effective capacity.</em> This means that quality improvement will prevent products from being returned, thereby speeding the process.
Letter e,<em> </em><u><em>"more employee cross-training"</em></u><em> </em>will increase the effective capacity. Employees will be able to do many kinds of work, thereby <em>hastening the process</em> and producing more outputs.
