Strict deadlines force you to make tough decisions without leaving long-standing issues behind.A fixed price means a betrayal of commitment.Let the guest team and the customer work together, truly in the current project to do the actual evaluation, by the customer control their function and budget.How to estimate project cost and time is another science.1.

If the pass event is received in the unlocked state, it is migrated to the locked state and the lock function is called. If the coin event is received in the unlocked state, it remains in the unlocked state and calls the Thankyou function. If the pass event is received in the locked state, it remain

and cannot be overused. If a class has hundreds of different interfaces, some of which are separated according to the client program, others are separated by version, then the class is hard to figure out, and this kind of hard-thinking is very frightening.12.5 ConclusionFat classes can cause unhealthy and harmful coupling relationships between their client programs. When a client program asks for a change to the Fat class, it affects all other client programs. Therefore, client programs should

following code: Public class base{ publicvirtualvoid f () {/*some code* / }}publicclass derived:base{ publicoverride void f () {}}The function f is implemented in base. However, in derived, the function f is degenerate. Perhaps, derived programmers think that function f is useless in derived. Unfortunately, base users do not know that they should not call F, so there is a substitution violation.The existence of degenerate functions in degenerate classes does not always mean that the LS

Code is often corrupted. With the addition of one new feature, the structure of the Code gradually degrades when an error is handled. If you ignore this, this kind of degradation will eventually lead to tangled and difficult to maintain chaotic code. The XP (eXtreme Programming) team uses regular code refactoring to reverse this degradation. Refactoring does not change. A series of small modifications are made to improve the system structure on the premise of code behavior. Every transformati

Introduced: In agile software development, the speed of code generation is much higher than that of traditional waterfall. Because we have made the time more compact. How can so much code guarantee the quality of the code? Many people may think directly of static code detection tools. Yes, those are the ones that can define a code-checking rule to ensure the qua

In the agile development framework of scrum, the most important part is the Sprint plan meeting. If the meeting fails, the whole sprint will make the scrum team suffer and it is difficult to complete the initial sprint goal. After several attempts, we finally found our own model. These methods and principles are the best for us. Based on our own knowledge and our own project scenarios, we may not try them o

The SCRUM method was proposed by Ken schwaber and Jeff Sutherland to seek development methods that give full play to object-oriented and component technologies. It is an improvement to iterative object-oriented methods, the name is from rugby (in the game, each player should always make a global judgment on the field, and then strive to achieve the same goal through collective action-victory ). The SCRUM method was originally developed by Easel (1993)

most likely types of changes, and then construct an abstraction to isolate those changes. P97 7. This is not easy to achieve. Because it means you need to guess the changes that may occur during the growth of those applications based on experience. If the developer guessed it was correct, they would be successful. If they guess wrong, they will suffer. And in most cases, they will guess wrong. P98 8. OCP compliance is expensive. It takes time and effort to create a correct abstraction. At t

Introduced: For story, an important measure of its size is story point, which is not equivalent to the function point in the software workload assessment, because story is simply a rough relative estimate of the size of the story, and function Point is used to measure the exact size of a functional module and to participate in the calculation of the formula, which is clarified here. The estimation of story point is a very deep learning, and we canno

I was a little touched when I stayed alone on the weekend! I think I am still poor in software design, so I decided to go to a chart. There are really a lot of chart computation books! Finally, I selected a design classic-UML modeling and pattern application, which is a little expensive. I spent a few dollars. It feels good to have bought a book! In fact, I think my current development method is also an im
