Software Craftsmanship raises some of the thorniest and most sensitive questions about software development and comes to the controversial conclusion of finding answers in a system that has thrived for hundreds of years: technology. Software Technology is a systematic expression of the author’s ideas and attempts to answer the difficult questions that have been plaguing the software industry. How should we restructure the process of building software, such as we want it to be effective?

 

The author of Software Craftsmanship has been emphasizing the role of the craftsman in the project. Craftsmen sounds is a very old word, the craftsman in other industries is a what kind of person I want to say, must be done in the field of a good man, I explain the below mentioned software process artisans do what kind of person, craftsman is mentioned there is a very rich in the process of software development experience, after years of development, products are well received by customers, has a certain reputation, they can submit a robust, high quality of the user application. A good craftsman can make or break a project. This shows that the human factor plays a very important role in the development of the project. Someone I have been thinking without learning software engineering in software development has a very important role in understanding of software engineering make me realize software can also like assembly line engineering, development mode, people do not development process, mainly the development process of software engineering control, a relatively fixed process, as long as people do some mechanical work can complete this project. In the current environment, software engineering ideas are still dominant, but software technology ideas also have their base of support, such as workers in the open-source community.

 

Software technology of the main pressure is a very important role in the whole project, software process is very strict requirements of the team, the team first small number, no more than 15 people, the general team is three people, but for the team of personal ability request, the other teams also are in high demand of health, a more stable team, team members can develop the tacit understanding.

 

The book Software Craftsmanship gives us a good development model, but many projects in the current environment are developed using software engineering ideas. Why is this? In my analysis, the main reason is that software technology requires too much of the team, and there are too few excellent craftsmen, so it is difficult for many companies to organize such an efficient team. Right now, the idea of software craftsmanship can only be seen in the open-source community, where many of the true craftsmen are gathered.

We are at the point of life that in a few years we all be fully working adults. It is crazy to think that 4 years of college just flew by so fast. This semester the software capstone class will be the most interesting and challenging I believe. When it comes to reading a book, I have no patience at all, but after reading the introduction, something about this book: Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman is making me want to read it appropriately. It is possible to be that I can relate to this book on so many levels and it is relevant to me. After just reading the introduction I feel like it changed the way I think and view my profession.

All the patterns in the book are interesting and powerful in a way that we can adapt and combine these patterns in many ways and situations. One of the patterns that stood out to me the most was “Be the worst” from chapter four. The author has explained the concept very well in which it states that “Surround yourself with developers who are better than you. Find a stronger team where you are the weakest member and have room to grow” This statement Is very interesting and when I think deep into it, I believe that being worst in a team at least for me is a motivation to work hard and grow to improve. The goal is not to stay the weakest but instead work my way from the bottom to the top.

The author also talked about the risk factor that associates with being worst in the team including dragging the team down, good teams do not tolerate you, and the risk of being fired. Although I do agree that in situations all these scenarios could be possible but on the positive side this can motivate a person to improve and build a mindset that helps the individual. I do not think I disagree with any aspects of the pattern but, these patterns and the whole book have certainly changed the way I think about a certain aspect of software development. I realized that I need to work even harder and push myself to the limits for me to get where I want in life.

Software frameworks are reusable “semi-finished” software for domains (such as ERP, computing, etc.) that implement common parts of the domain and provide well-defined points of variability to ensure flexibility and extensibility. In other words, the software framework is the softwarenation of the results of domain analysis and the template for the final application in the domain.

With the expansion of software scale, wide application and the development of software reuse technology, the software reuse based on subroutine and class has a lot of shortcomings:

(1) The library of the subroutine is becoming more and more huge, which makes it difficult for its users to master

(2) Most classes are too small to do all the useful work by themselves

It is for these reasons that a set of classes (modules) are considered as a whole in reuse, resulting in a software framework. The software framework contains at least the following components:

(1) A series of modules to complete the calculation become components

(2) The relationship between components and the interaction mechanism

(3) A series of variable points (hot spots, or adjustment points)

(4) Behavior adjustment mechanism of variable point

Developers through the software framework behavior adjustment mechanism, peculiar to the general application domain software module bound to the variable point of a software framework, and got the final application system, this process is called software example of a software framework, the existence of software framework allows developers will be the main energy on the development system of the module, so as to improve software productivity and quality.

The behavior adjustment mechanism of the software framework refers to how to adjust the variable part of the framework for the specific application and how to add the method and rules of the specific application module at the variable point.

Ii. Software architecture

Software architecture is a sketch of a system. The objects described by software architecture are abstract components that directly constitute the system. The wires between the components describe the communication between the components explicitly and in relative detail.

Software architecture, by definition, is divided into two camps of ‘constituent’ and ‘decision-maker’, which are described as follows:

The componentized view of software architecture is that the system is described as computing components and their interactions. It has two very obvious characteristics:

Focus on the object of architectural practice — software, with the software itself as the object of description.

This paper analyzes the composition of the software, and shows that the software is not a whole in the sense of “atom”, but a whole composed of different parts connected through a specific interface, which is very important for software development.

Decision-makers believe that software architecture involves a series of decisions, mainly including:

Organization of software systems

Choose the structural elements that make up the system, the interfaces between them, and the behavior that these elements exhibit when they cooperate with each other

How do you combine these elements so that they gradually synthesize into larger subsystems?

The architectural style used to guide the organization of the system: these elements and their interfaces, collaborations, and combinations

Software architecture is concerned not only with the structure and behavior of the software itself, but also with other features: usage, functionality, performance, elasticity, reuse, understandability, economy, and technical constraints and trade-offs.

Personal understanding: When software engineering has a certain scale, software development does not exist in the form of data structure + algorithm, but “divide and conquer” software based on many factors such as technical choices and user needs. The main task of the architect is to divide the software into different modules and define the interfaces between modules.
