When I returned to the last listening to the lecture, the first part was "the transformation of the model", which mainly said that the waterfall model is not established at the opening, but because misunderstand is widely spread. At the same time, iterative development is not the successor or improvement of waterfall development, but another way of thinking of software development. That is, another model.
When this is finished, it has used a quarter time. When I was resting in the middle, I heard someone this comment "How to talk about these? It is better to talk about how iterately develop".
Oh, two cows are chatting, one saying: "The last nest is very popular? I can't eat anything." Crazy cow disease? "
Indeed, the "waterfall model is wrong" seems to be really no means. It seems that everyone knows. The problem is, then what is the way you use? Or say that if the conditions are ideal, what would you think of the software development?
Examples of Larman are very interesting. He uses the medieval blood-blooded therapy to develop a modal shape than the integrated software. Blood-blooding therapy is the theory proposed by the father of the ancient Greek Medicine, which is considered to have 4 liquids in the human body: blood, mucus, yellow bile and black bile. Liquid imbalances will have a disease. (Is it a bit like a Chinese doctor) According to this theory, it can cure the blood in the body by gravitation.
Is this kind of therapy? Modern health knowledge can judge that it is invalid, not because of the means of implementation, but the basic prerequisite is wrong. This premise is a model. That is, if you have been separated from technical restrictions, things are fundamentally developed, and ideal.
Under technical limits, individual behaviors with different regions may sometimes differ, and the greater the limitations, the smaller differences. People who are surprised by fire will not be better than the monkeys; there is no difference from the behavior of people and stones that fall from high federation. However, if it is just in the technical level, the guidance value of all the behaviors of individuals (it can often be seen in the forum ", what methods can be used to do it," can do it. " Just like thinking that the bullish donkey and the millennium are not different.
A 乞丐 said: "The most beautiful thing in the world is too emperor. The clothes of the emperor are all gold." Another 乞丐 said: "How to do, hard clothes, how to give people a gift what"
People who have exposed new models often use past thinking, or just put the original experience to a new environment. Considering the question that each to understand the last understanding of the child is a problem, "Why can't the people in the earth will fall? Isn't their head?" "Seven steps to die, RUP" (
"Non-programmer" No. 37) also describes the performance of such a way of thinking in the software process.
嫦娥 is a talented medicine to fly on the moon.
Wanners are covered with fireworks to fly on the sky.
The "From the Earth to the Moon", the spacecraft is emitted from a large diameter artillery. The way to return to the earth is to find a cliff on the moon, push the spaceship, and fall back to the earth.
Based on the old model, even the fantasy reflection is still just the technical means of the old model, the real world is often more broad and profound than fantasy.
