Software Engineering Process and process improvement

The software process mainly refers to the software engineering process, that is, the sequence and relationship of various development stages and activities within the Organization during the software development process. The organic operation of these activities can complete the software development process.

 

Some people regard the software life cycle as a software engineering process, which is biased. The software life cycle refers to the process from nothing to existence and then to the extinction of software, and is the characteristics of the software itself. The software engineering process is the process of analyzing, designing, implementing, and maintaining the software or modifying the software. For one-time software development, the software engineering process may be similar to the process from scratch in the software life cycle, but for non-one-time software development, that is, the software must maintain a longer life cycle through multiple version updates, and each new function development process requires the software engineering process. Therefore, it is necessary to correctly distinguish the relationship between the two.

 

The software engineering process is an engineering process that ensures smooth and repetitive software development through reusable processes. To achieve this goal, the concept of software engineering process also matures and develops with the expansion of software scale and complexity. In order to express different processes in a concise manner, a software engineering process model is proposed, referred to as the process model. A set of process systems or methodologies are formed by some visualized and standard names. Currently, common process models include waterfall models, incremental models, unified process models, and agile models.

 

Any process model is defined according to the ideal environment. To use a process model to standardize the software development process, I think the following processes and ideas are very important.

 

1. correctly understand the role of the Process Model

As mentioned above, a process is a sequence of activities. No matter whether a process model is used or not, as long as you are working on software development, there must be a series of activities. This is naturally a process. It can be seen that the process exists objectively and does not disappear because the process model is not used. However, emphasizing and standardizing the software development process can make the original random activities standardized to the stage and activities agreed by everyone, forming an organic and smooth process, this can reduce the adverse effects of random human factors and enhance the degree of teamwork. This is the role of the process model in binding and standardizing software development activities. It is not used to show off or rate.

 

2. Correctly Understand the customization of the Process Model

Any process model has its applicable environment and shortcomings. This is an important part of model selection. Different enterprises, different projects, and even different teams may need different process models. They blindly pursue new models without considering the actual situation, staff do not adapt, and departments do not cooperate, in most cases, failures are inevitable. Even if the process model has been selected, it is necessary to make adjustments according to the actual situation by following the process of process construction, removing unsuitable parts, and making long-term adjustments, use accumulated experience and data to form the most appropriate process in the process of continuous improvement and optimization.

 

3. Process Model promotion must be in line with the corporate culture

The same process model is customized. Within the enterprise scope, the process model must be integrated with the enterprise culture. If it is a step-by-step enterprise, it is likely that the traditional waterfall or planning-driven model will be suitable, while the agile model will be different from the enterprise culture, is not suitable for the overall environment of the enterprise. A good process must be perfectly integrated with the corporate culture. Otherwise, the process will lose the soil for survival and cannot take root in the enterprise.

 

4. process improvement is from top to bottom

Process improvement is a revolutionary nature for enterprises. Of course, any change will pay a price and will face resistance. Therefore, enterprises should profoundly realize that process improvement is not as simple as setting up a process improvement group, and should proceed from the strategic height of the enterprise, from top to bottom. It would be blank if only senior leaders say that the improvement is not feasible. If only some employees or departments are promoting the process improvement and the senior leaders are not able to cooperate, there is no result. Therefore, we must be cautious in improving the process, supplement the necessary knowledge, and have the determination and courage to make changes and stick to the end. The most important thing is to carry out all-round improvement from top to bottom.

 

5. process improvement should be supplemented by tools

A process is a complex and invisible thing. For process construction, management, and improvement, appropriate process management tools, especially configuration management tools and project management tools, need to be introduced, the former is used to record the process changes of various configuration items and form valid process data. The latter is used for visual project management and is abstracted as concrete.

 

In short, the introduction of software engineering processes will undoubtedly standardize the software development process, so as to improve the quality of software products and reduce the risk of failure. With the further development of software engineering process, more and more process models are being created, either agile or plan-driven, in the future, there may be more models that drive the combination of the two. In the development of process models, we have also noticed the development of software engineering methods, software engineering management, and other disciplines. These are an indispensable part of software development and an organic whole, they are described from different perspectives and cannot be separated. Silver bullet will not appear, but the integration of the process and corporate culture can make software development develop in a more standardized direction, which is of far-reaching significance of the process model.
