Easy to use, no doubt

It's easy to use and difficult to use. Is this old saying correct?
In today's society, many people may think that the application is no longer applicable. However, we still think that the problem is divided into two parts. I think there are reasons for inapplicable and applicable reasons.
The reason is not applicable. If you search too much, I will talk about the reasons that have recently occurred to me:
The company wants to buy a server hosting service. I am the it director of the company. Naturally, I am here to do this. First, contact the server manufacturer to discuss the price. Then, find the hosting service provider. Let's talk about the price.
Report to the boss after the talk. The boss instructs him to leave the phone number of the contact and the boss will talk about it. I used to do all my work in vain. I was wondering, what do you want to discuss with others about the price? About servers, do you understand how to configure servers? Do you understand the performance of the configured server? Do you know about network hosting? Do you understand bandwidth? Do you understand technology? Yes, you don't know. Why do you come and talk to others? In my opinion, the technical people talk about the price from the technical point of view. Maybe there are some discrepancies in the price, but in the end, people who don't know the price will talk about it, the price is "real", but what is the authenticity of the "goods? Therefore, in terms of management, especially for technical personnel, it is necessary to renew for use; otherwise, it will not be used.
