Final answer:
For a suggestive selling program, management should train employees on communication techniques to inform customers about complementary products and services effectively.
Step-by-step explanation:
When management implements a suggestive selling program, an important activity to be included is training employees on effective communication techniques. This involves coaching staff on how to inform customers about complementary products or services, understanding customer needs to make appropriate recommendations, and having the knowledge about the products to answer any questions. For instance, a server in a restaurant might suggest a specific wine that pairs well with a customer's meal choice, or an electronics salesperson could recommend a protective case when a customer purchases a new smartphone.
