Final answer:
Product quality would have the most long-range impact on the organization.
Step-by-step explanation:
In assessing organizational risk in a manufacturing firm, the factor that would have the most long-range impact on the organization is product quality.
While all the options can impact an organization, product quality directly affects the reputation and customer satisfaction of a manufacturing firm, which can have long-term consequences. Poor product quality can lead to a decline in sales, loss of customers, and damage to the company's brand image.
