You inadvertently get along with as much as possible to let him understand some computer knowledge, you can also privately communicate with the customer so that they are in the boss in the time to urge the work progress, so that the customer to the boss to put some pressure
The boss is anxious to see each time the computer card If the number of times he is also tired of it will give you a replacement!
One more answer, a pig's answer can be borrowed
Lucifer of the Apocalypse 01:48:48
Actually, from the point of view of the operator, want to let a person out of the money, you have to clearly tell him the inputs and returns. That's the most immediate thought of any businessman. How much do I put in and how much do I get out?
As you said, change the computer, so the communication is more difficult. Without my such eloquence easily do not try (pig heart, this you can not add) why we do not change a little, to convince the boss, the company's computer upgrade, replace the CPU, memory sticks, hard disk, and even the motherboard, to keep the monitor, chassis, mouse keyboard, etc. can be used. Because a bit of computer common sense know that these replacements and buy a new one is the same effect, however, you can save a lot of money, you can say, this is for the boss to consider, but also can be said to be for you to make you better and easier to convince the boss. Without further ado, the point begins to first tell the boss what benefits an upgraded computer can bring. For example, a simple math problem. Upgrading a computer might cost about a thousand dollars. A company with ten people using computers to do things, ten employees can bring the boss two hundred dollars in profit in eight hours. After replacing the computers, as the efficiency of the work increases. Ten employees will be able to bring the boss three hundred dollars or even five hundred dollars in profit. To summarize it is (10 * 1000 = 10000 (yuan) 300-200 = 100 (yuan) 10000/100 = 100 (days)) That is to say, after the profit increase, up to three months to recover the cost, and all those later increased profits are net profit. (This is just an example and can be modified to suit your specific situation.) Also. Tell the boss that sooner or later the computer is going to have to be updated, and why not do what you can do sooner and earn sooner?
After that, then tell him not to do that, there is a possibility of what is the situation, for example, now the computer hacker has been commercialized, many masters are hired to become someone else's mercenary, specializing in attacking competitors' computers, stealing confidential information. This leads to the loss of our company's core competence. Because all your secrets are in the hands of others, how you make a move and people competing with people are very clear, then how can you still compete with others. (To this point, you feel the need to cite an example of this, specific I will not say)
Of course, the last thing to remind is that this is just a rough idea of me. Specific to your own according to your understanding of your boss, to find a suitable method, I can only provide ideas, the expression of the method is to rely on your own, because I do not know your boss. But I think the idea is not wrong, different people say the same words, the expression method is not the same. The effect is not the same, that depends on your own comprehension.
