1, simply put, software quality is "the degree to which software is consistent with explicit and implicit requirements".
2. Specifically, software quality refers to the degree to which the software meets the clearly stated functional and performance requirements, the development standards clearly described in the documents, and the hidden features that all professionally developed software should have.
3. The main factor affecting software quality is the measurement of software quality from the perspective of management.
4. It can be divided into three groups, which respectively reflect the three viewpoints of users when using software products. Correctness, robustness, efficiency, integrity, availability and risk (product execution); Understandability, maintainability, flexibility and testability (product modification); Portability, reusability and interoperability (product transfer).
What is the difference between software quality, software quality assurance and software quality management? Software quality is "the degree to which software is consistent with explicitly and implicitly defined requirements". Specifically, software quality is the degree to which the software meets the clearly stated functional and performance requirements, the development standards clearly described in the document, and the hidden characteristics that all professionally developed software should have. The main factor affecting software quality is the measurement of software quality from the perspective of management. It can be divided into three groups, which respectively reflect the three viewpoints of users when using software products. Correctness, robustness, efficiency, integrity, availability and risk (product execution); Understandability, maintainability, flexibility and testability (product modification); Portability, reusability and interoperability (product transfer).
Software quality assurance is to establish a set of planned and systematic methods to ensure that the developed standards, processes, practices and methods can be correctly adopted by all projects. The purpose of software quality assurance is to make the software process visible to managers. It verifies whether the software meets the standards by reviewing and auditing software products and activities. The software quality assurance team participates in the establishment of plans, standards and processes at the beginning of the project. These will enable software projects to meet the requirements of organizational policies.
Software quality management can be said to be a system or system, which controls the global nature of a software.
What is the quality of the software? Object-oriented method emphasizes class, package and inheritance, which can improve the reusability of software, locate errors and defects, facilitate users' participation, and is of great benefit to improving the quality of information system.
Component-based development, also known as "plug and play programming" method, is an excellent method absorbed from computer hardware design. This programming method is to insert the compiled "components" into the completed framework, thus forming a large-scale software. Components are reusable software components, which can be developed by themselves, used by other projects or purchased directly from software suppliers. When we find that a component does not meet the requirements, we can modify it without affecting other components, and it will not affect the realization and testing of system functions, just like transforming a room in a building without affecting the use of other rooms.
Why can software testing only verify software quality? But it can't improve the quality of software, because development is related to the company's operation, and testing is of course related, but testing is just inspection.
What is the relationship between software quality and software quality assurance? (Not the relationship between software testing and software quality) Simply put, software quality is "the degree to which software meets the clearly and implicitly defined requirements". Specifically, software quality is the degree to which the software meets the clearly stated functional and performance requirements, the development standards clearly described in the document, and the hidden characteristics that all professionally developed software should have. The main factor affecting software quality is the measurement of software quality from the perspective of management. It can be divided into three groups, which respectively reflect the three viewpoints of users when using software products. Correctness, robustness, efficiency, integrity, availability and risk (product execution); Understandability, maintainability, flexibility and testability (product modification); Portability, reusability and interoperability (product transfer).
Software Quality Assurance (SQA) is to establish a set of planned and systematic methods to ensure that the developed standards, procedures, practices and methods can be correctly adopted by all projects. The purpose of software quality assurance is to make the software process visible to managers. It verifies whether the software meets the standards by reviewing and auditing software products and activities. The software quality assurance team participates in the establishment of plans, standards and processes at the beginning of the project. These will enable software projects to meet the requirements of organizational policies.
Relationship:
Simply put, software quality is a noun and software quality assurance is a verb, which is a technical method and work to achieve excellent software quality. To some extent, software quality assurance is similar to software testing.

What is the quality of the software and what problems are reflected? In short, software quality is "the degree to which software is consistent with clearly and implicitly defined requirements". Specifically, software quality is the degree to which the software meets the clearly stated functional and performance requirements, the development standards clearly described in the document, and the hidden characteristics that all professionally developed software should have.
Software quality reflects the following three problems.
? Demand-software demand is the basis of measuring software quality, and software that does not meet the demand will not have quality.
? Specification-Software quality cannot be guaranteed without following the development rules defined in various standards.
? Expansion package-only meets the clearly defined requirements, does not meet the implied requirements, and the software quality is not guaranteed.
What is software quality assurance? How does it work? What is software quality assurance? Software quality assurance is a complex system, which uses certain technologies, methods and tools to deal with and adjust the relationship between software products when meeting the requirements, so as to ensure that software products meet or exceed the standards specified in the product development process. Its working principle is as follows:
(1) Make the quality characteristics as concrete and quantitative as possible.
(2) Find out the specific quality characteristics of each stage.
(3) Develop quality plans for specific products and corresponding projects.
(4) Check the quality test results.
(5) Conduct various quality reviews.
(6) Optimized and constructive quality assurance.
(7) Find and correct mistakes and defects as soon as possible.
(8) Pay attention to quality assurance.
(9) Independent quality test.
(10) Evaluation of application software quality assurance measures.
Software quality assurance 1, and define appropriate quality objectives.
Software is ultimately delivered to users, so software quality objectives should be defined from the user's point of view, and software should meet users' business needs and achieve a satisfactory user experience. The advantage of this is that you can't set the quality target too high, which you can't achieve with all your efforts, and you can't set the target too low, so you can't work for users. It is best to define the appropriate software quality standards according to the objective conditions such as time, resources and budget, which will not make the development team feel pain, but also satisfy the users.
Let everyone know the importance of quality.
Try to reduce software defects in the early stage of software development life cycle and avoid eliminating defects in the later stage, which will consume more time and energy. Benefits: After everyone knows the importance of quality, they will pay more attention to code quality psychologically and write high-quality software more attentively.
3, adjust the team's personal goals, into the quality assessment system.
Adjust the work objectives of teams and individuals according to business needs, incorporate them into the quality assessment system, and implement strict reward and punishment measures to * * * develop the work efficiency and quality of personnel. Benefits: Give appropriate rewards according to the performance of team members, let them know that improving software quality is a goal, and gradually form a habit.
4, get the right demand
Ensure that the project is moving in the right direction from the beginning of requirements acquisition. The deviation or error of requirements is the biggest headache for developers. A lot of rework and modification will put out the ignited * * *, and the correct requirements will bring a happy mood to developers. Benefits: reduce rework and retest cycles and reduce the overall workload.
5. Focus the test on the most critical and dangerous points.
In the case of limited time, it is impossible to expose all the defects through testing. At this time, we must grasp the key points, be targeted, and focus on testing the core function points to avoid major defects. Benefits: Eliminate key defects, even if no other defects are found, it will not affect the overall quality of the software.
6. Improve the design quality. Developers will code according to the architect's design documents. If the design description is not clear, developers may write code according to their own understanding, which may lead to the opposite result. Benefits: The code written with reference to concise and clear design will be simpler, cleaner, easier to test and rework, and the code will contain fewer errors, making it easier to diagnose and repair defects.
7. Rational use of automated testing tools
Traditional manual testing is difficult to cover all the function points of software, and some background functions can only be tested by tools. In addition, manual testing is inefficient, and repeated monotonous testing is a great test for the psychological quality of testers, which is easy to cause the slack of testing work and reduce the quality of testing. Benefits: Through the rational use of automated testing tools, the testing cycle can be shortened and the repeatability of testing can be improved.
Seeking adoption is a satisfactory answer.
