The details of ls can be referred to personally. First of all, we need to investigate the knowledge of new employees in order to understand everyone's level and conduct a thorough investigation of product knowledge (the examination paper is relatively simple), followed by the training and assessment of the company's internal system. Of course, it will be easier to recruit some employees with this knowledge when recruiting. Then, arrange the old employees of the product, preferably at the level of product supervisor, to train the product, including the basic knowledge of the product.

Then the people in the training department train the speaking skills and introduce the product knowledge. After all, sales pay attention to communication skills.

Finally, business etiquette training.

This is my general idea, for reference only.
