One:

The biggest advantage of the Big Bang model of software development is

simple

Analysis: there is almost no plan, schedule and formal arrangement for software development in the Big Bang mode. All the energy is devoted to developing software and writing code, with almost no testing. And the test after the rapid completion of the software is to tell the customer the determination of the software, and it is impossible to modify the software from scratch. From a project management point of view, the software delivered by the equipment will hinder delivery because of the work of the software tester.

Two:

How to know the time of software release by using the mode of portable edge modification

Teams that adopt this approach usually have only rough ideas at first, then do some simple design, and then begin a long process of writing, testing, and correcting defects back and forth. When you think it's enough, release the product.

Three:

Why doesn't waterfall mode work well?

The waterfall mode is tested only at the end, so some fundamental problems may arise at an early stage, but it is only possible to guide the preparation of the product release. Because, ah, the cost of repairing defects increases over time, so if the software finally has a problem, the cost of modification will be very huge.

Four:

Why do software testers like spiral?

In the spiral software development model, testers can affect the product as soon as possible by participating in the initial design phase, and they can get a clear picture of the product; and they are not in a hurry to conduct a comprehensive test at the last minute at the end of the project. Software testers are testing all the time, so the final step is just a job to verify that everything on the surface is all right.
