When a company makes a deal with the customer, it is very important that the person making the deal has both interpersonal skills and business knowledge. Business knowledge is a key factor in making a business deal. If the team leader does not have full understanding on their product then the customer will not be as interested. In addition, if the customer does not receive all the information on the product, they will still have doubts and will very likely not sign off on the product. Interpersonal skills are another characteristic that the team leader should consist of, as well. When the team leader has this type of skill set, the customer will feel more comfortable with the deal and be able to relate more. If the team leader just basically says this is my product and that’s it, the customer will not feel as welcomed to the idea. Both these traits play a big role in successfully making deal with customers.
