The first basic assumption is that the quality of a software product is largely affected by the process of developing it. Therefore, it is necessary to improve the soft The quality of each piece of product needs to improve the quality of the software process. The second assumption is that the quality of the software process is that the process is clearly defined, managed, and measured And the degree of continuous improvement. This is reflected by the process capability. The input for the evaluation is defined in ISO /IEC 15504-2.The GB/T 25000 standard can be used when evaluating the organization’s measurement and quality processes. For a reference. The ISO /IEC 15504 series of standards provide guidelines and identify the measurement framework of process capability and the following requirements. a) Perform evaluation; b) Process reference model; c) Process evaluation model; d) The compliance of the verification process assessment. A.5 ISO 9000 series of standards The ISO 9000 series of standards are designed to assist organizations of all types and sizes to realize and operate an effective quality management system. Types of products, the series of standards include. a) ISO 9000.2015---describes the basic points of the quality management system and specifies the terminology of the quality management system. b) ISO /IEC 90003.2014---provide an organization to apply ISO 9001 for procurement, supply, development, operation and maintenance of computer software Provided a guide. c) ISO 9001.2015-specifies the requirements of a quality management system, in which an organization needs to demonstrate that it can meet customer needs The purpose of the ability to manage and control demanded products is to improve customer satisfaction. d) ISO 9004.2018---provides guidance for the organization's sustainable quality management, while considering the effectiveness and effectiveness of the quality management system rate. The goal of the standard is to improve organizational efficiency and customer and other stakeholder satisfaction. e) ISO 19011.2018---provides guidance for auditing quality and environmental management systems. Together, they form a set of quality management system standards to promote mutual understanding in domestic and international trade. In these international standards The required quality management system requirements and the requirements specified in the ISO /IEC JTC1/SC7 system and software engineering standards are complementary to each other. The quality management system method encourages organizations to analyze customer needs, define processes that help customers to achieve acceptable products, and ensure the process Controllable. The quality management system provides a framework for continuous improvement, increases the possibility of customer satisfaction, and improves the competitive advantage of the organization. Potential. At the same time, it also brings confidence to organizations and customers, and guarantees the provision of products that fully meet their needs. ISO 9000.2015 describes some basic points of the quality management system, which form the subject of the ISO 9000 series of standards, and at the same time The relevant terms are defined. This international standard applies to. a) The organization seeks advantages by implementing the quality management system; b) Organizations gain confidence by satisfying the product needs of their suppliers; c) the user of the product; d) People and organizations (e.g. suppliers, customers and regulatory agencies) who need to reach a consensus on the terms used in quality management; e) Internal or external personnel and organizations that evaluate the organization’s quality management system or audit its compliance according to the requirements of ISO 9001 (E.g. auditors, regulatory agencies and certification bodies); f) Internal or external personnel and institutions that advise or provide training on the organization's quality management system; g) Developers of relevant standards. ISO /IEC 90003.2014 provides guidance for organizations to apply ISO 9001.2008 to obtain, supply, develop, operate and maintain computer software south. This guide is applied to computer systems. a) As part of a commercial contract with another organization; b) As a product available in the marketing department; c) Support the business process of the organization; d) As software embedded in hardware products; e) Provide software operation, maintenance and support services.

This international standard identifies the technology, life cycle model, development process, activity sequence, or organization that should be resolved. Structure-irrelevant issues. The guidelines and the identified issues are expected to be extensive, but not exhaustive. The scope of an organization’s activities includes in addition to In areas other than computer software development, the relationship between the computer software foundation of the organization's quality management system and other aspects should be taken as a whole The body is clearly recorded in the quality management system. ISO 9001.2015 specifies the requirements of a quality management system, in which the organization. a) It needs to demonstrate its ability to provide products that are consistent with the needs of customers and applicable regulations, and b) Aimed at enhancing customer satisfaction through the effective application of the system. include. 1) The continuous improvement process of the system and the guarantee of customer compliance, and 2) Applicable regulatory requirements. All the requirements of this international standard are universal and are intended to be applicable to organizations of different types, sizes and offering different products. When any requirement of this standard is not applicable due to the characteristics of the organization and its products, it can be considered to be deleted, but this reduction is limited to For a specific subset of requirements. Such reductions must be reasonable and must not affect the organization's provision of products that meet the requirements of customers and applicable laws and regulations. The ability or responsibility of the product. ISO 9004.2018 provides guidance beyond the requirements given in ISO 9001, mainly to consider a quality management system. The effectiveness and efficiency of the department, thereby improving the potential of organizational performance. Compared with ISO 9001, the goal of customer satisfaction and product quality Targets can extend to include the satisfaction of stakeholders and the performance of the organization. This international standard applies to organizational processes and also applies to quality management guidelines that can be deployed and implemented throughout the organization. The standard coke The point is to obtain continuous improvement through the satisfaction measurement of customers and other interested parties. ISO 9004 is composed of guidelines and recommended standards, and is not applicable to certification, regulations, or contracts, nor is it applicable to the implementation of ISO 9001 guide. ISO 19011.2018 provides audit criteria, audit project management, quality management system audit operations, and environmental management system audits. And a guide to the competence of quality and environmental management system auditors. This standard applies to all organizations that need to audit internal and external software quality control and management, and/or environmental management systems. In principle, it is also possible to apply this international standard to other types of audits, evaluations, and evaluations. In this case, it is necessary Special consideration is how to define the required skills of audit team members. A.6 ISO /IEC 29119 ISO /IEC 29119 aims to define an internationally recognized standard for software testing, which can be implemented by any organization in any form Used when testing the software.
