How to be a good pre-sales engineer

I have been doing pre-sales in two companies for 6 years. Simply put to do a good pre-sales must have the quality of two points: speak, write. 1 speak, you have to speak your company's things head to head, speak alive, even exaggerated point you have to speak like a commentary, so that you speak of things y attracted to the customer. 2 write, you have to write a good program writing skills. Write program generally have three points: one is a very good program design capabilities, such as the organizational structure of the program, the content of other programs how to all for me; two is the writing skills, writing program often have a lot of content is needed according to the user's needs, their own organization of the language, through the personalized elaboration, to illustrate how you are to mention the company's products, experience, team strength to help users solve the problem; third point! Is fine, write something must be detailed, to avoid all kinds of errors, especially low-level errors, once the user or the leader to see the errors in your program, you will have doubts about your responsibility. (Compared with the ability, the boss is more important to the staff's sense of responsibility, the same reason customers are also very important to the manufacturer's sense of responsibility) As for the rapid improvement of the pre-sales work ability method, simply put, I recommend that you do the following two points. 1, learn more about the company's products, to deepen the understanding of the company's products, don't just float on the surface, be sure to look y into the "Why". 2, Do some more ppt, and according to these ppt own well written speech, if necessary, I suggest you memorize one or two commonly used speech. That's it. In the write more, you will see the boredom.
