Answer:
b. It reduces productivity and revenue growth.
Explanation:
The disadvantage of outsourcing is that it reduces productivity and revenue growth. Due to outsourcing, the company ceases to produce a product in its own facility and gives the entire production responsibility to third party. This is because the company might not have the capability to produce on its own or it might be costly for the company.
Since the company has to give production cost, over runs, labour cost etc along with margins to the third party, hence there is a decrease in revenue growth and productivity of the company.
