It has been mentioned in the book that from the initial simple programming to the current engineering team's organization development, the realization of a software is the ultimate goal, so, implementation is the essential requirement of software development. It is due to the need for the implementation of language tools, methods, procedures and implementation objects. In order to achieve a larger-scale software system with a team organization model, and team collaboration determines the production process model. The production of tools is still in the need of software implementation. In the system of software engineering, realizing the essential demand and the basic motive of software development, as the hand of God has promoted the formation of software engineering theory system in the past decades.
The way to think about a problem can be a point and a plane, or it can be strenuous efforts. The industry's most commonly used vocabulary is the "top-down" or "bottom-up" distinction. The tools, methods, and procedures described in "cow poo" are also known as the three elements of software engineering. In this book they are divided into thinking, not to isolate the three levels. They are actually interacting with each other. For example, "process" problem, there are both the implementation of the process tools, there are related process method theory. Although I say the method is "the result of a programming practice based on a data structure", this is a very narrow definition. This definition is effective in the development of the process (or the definition of "development method"). However, "demand", "design", "Test" and so on other aspects also have their own methodology, even in the specific link, the process itself has methodological problems, which does not include management methods and so on.
