but difficult to understand. With a concrete example, Neal Ford will help you lay a solid foundation in the evolutionary architecture and agile practices of emergent design. By postponing important architectural and design decisions until the last moment of responsibility, you can prevent unnecessary complexity from r

Introduction: Software metrics can help you look for hidden design elements in your code so they can become idiomatic patterns. This phase of evolutionary architecture and emergency design explains how to use metrics and visualization to discover important code elements that are masked by complexity. One of the challenges of emergent

Introduction: The ability to discover and accumulate idiomatic patterns is critical for emergent design. It is also very important for design to be the expression of the code. In the 2nd installment of this series, Neal Ford will continue to discuss the intersection of expression and pattern, illustrating these concepts through idiomatic patterns and formal

In previous installments, I have begun to introduce the harvesting of domain idiomatic patterns (solutions for urgent business problems) by using domain-specific languages. For this task, DSL work is good because they are concise (with as few noisy syntax as possible) and readable (even by developers), and they stand out from more API-centric code. In the previous issue, I had shown how to use Groovy to build a DSL to take advantage of some of its features. In this section, I'll end the discussi

A common kind of agile development practice is TDD. TDD is a pattern of writing software that uses tests to help you understand the final steps of the requirements phase. Write the test first, then write the code, which will consolidate your understanding of what the code needs to do. Most developers think that the main benefit of TDD is the resulting integrated unit test set. However, if executed correctly, TDD can improve the overall

Introduction: After using the evolutionary architecture and emergent design in the technical discovery code described in the prior installments of the emergency design, you need a way to get and take advantage of these design elements next. This article describes two ways to get idiomatic patterns: Capturing patterns a

what about the existing code? Now, let's look at how to use combinatorial methods to discover hidden designs. Idiomatic patterns You may be familiar with the formal design pattern movement, which originates from the designing Patterns of Gang of Four. It describes the common patterns that apply to all projects. However, each solution also contains idiomatic patterns, which are not formal enough, but are widely used. Idiomatic patterns represent com

of the method, the team's abilities are constantly improved, and the problems that can be handled become more and more complex, maybe they can handle the problems that 20 teams of people using heavy-duty methods can handle. However, if the number of people in the team suddenly increases to 12, the team will certainly have problems, and his performance may not be as good as that of the team of 20 people. When the number of people increases, the original method must be adjusted as appropriate. Fo

However, if the number of people in the team suddenly increases to 12, the team will certainly have problems.The performance may not be as good as that of the team of 20 people. When the number of people increases, the original method must be adjusted as appropriate. For example, you can add some heavy method skills in

Introduction:Team design is an important practice in Agile Methodology. The team we are talking about here is not a plural person. A group of people is a group and cannot form a team. To become a team, you have to do a lot of work. The reason why we consider architecture design on a team basis is that software development is not a personal task, especially arch

Let's go back to January 15, 2002, where Alan Cooper, the father of interaction design, and Kent Beck, the founder of extreme programming, are at the PK. The topic is "When interaction design encounters agile development ". Just like the two masters in the novel, the two sides won't compete in the three hundred round, but the two sides will eventually shake hands

XP emphasizes a simple design principle: the functions that can be implemented using arrays are never linked lists. In other agile methods, simple principles are repeatedly emphasized. In this chapter, we have a comprehensive understanding of simplicity. Context To what extent should the architecture be designed? Problem The software architecture is very complex, with a large number of documents and charts.

personnel, the architecture design of the next iteration may have to wait until the coding peak expires. However, multiple staggered iterations may cause version issues. For example, an architecture problem is found in the Code of this iteration and fed back to the architecture design group, however, the architecture design group has started the architecture
