Answer to Question 1
The NAICS classification is based on production activities. NAICS is similar to the International Standard Industrial Classification (ISIC) system used in Europe and many other parts of the world. NAICS divides industrial activity into 20 sectors. NAICS contains 1,170 industry classifications. NAICS is comprehensive and up to date, and it provides considerably more information about service industries and high-tech products.
Answer to Question 2
During face-to-face communication, such as personal selling sales promotions, verbal and nonverbal feedback can be immediate. Instant feedback lets communicators adjust messages quickly to improve the effectiveness of their communications. For example, when a salesperson realizes through feedback that a customer does not understand a sales presentation, the salesperson adapts the presentation to make it more meaningful to the customer. This is why face-to-face communication is the most adaptive and flexible, especially compared to digital, web-based, or telephone communications. In interpersonal communication, feedback occurs through talking, touching, smiling, nodding, eye movements, and other body movements and postures.
