BUS528: A comment about the three factors of projet

In the first class, we learned that a project has three factors:
clear spec, timing and budget.
I am impressed how similar this is to the "advice" from our ex-Chairman Mao.
When I was in elementary school long long ago, which was the end of culture revolution. There was a very very popular quote from Chairman Mao:
We must build our socialist country with "many", "fast", "good" and "cheap".
This 4 factors cover the 3 factors we learned in our first class.
Prof Tao told us these three factor are controdictory with each other. If you want cheap, you may sacrifice spec(good), and if you want "fast", you may also sacrifice "good", let alone "many".
It's very easy for a leader to say "many", "fast", "good" and "cheap", but it's very difficult for people to execute it.
In those days, if you doubt about these four factors, you have political issues, even "counter-revolutionary".
In China, if you say good word, even though it's not practical, people will still regard at least you have good purpose. But if you say anything sounds not "mainstream", even though it's practical, people will think you try to be lazy or be bad. Gradually people become so unrealistic, people even think they can make 10 thousand jing of rice with small land, and so on. And many people still use this philosophy to treat Chairman Mao's achievement and mistake.
People think Chairman made mistake with "good purporse". This is very different from western people. Result is more important than "purporse". It's very difficult to evaluate "purporse".
