In Business ABC, the number of clients (buyers) increased after an advertisement campaign. The manager concludes that the number of clients increased because of the advertisement campaign. Discuss in detail why the manager’s conclusion can be wrong?
How can we actually find out whether the advertisement was successful? Discuss in detail.

Due to quality.

Explanation:

The manager’s conclusion can be wrong because the number of clients increases due to the quality of the product. Clients or buyers choose a product of a company due to its quality and maintenance. If the quality of a product is not satisfactory, the number of buyers decreases and the company will not be producing the product anymore due to no sale so we can say that quality is the main reason for increase in number of buyers not the advertisement campaign.
