In the previous articles, we have understood the concept and significance of software quality assurance TQA. This article focuses on the work of TQA, hoping to give you some help. You are also welcome to log on to the website of Shandong Software Evaluation Center http://www. × × / to study and discuss together. 1) Information system planning and selection u system planning consultation: assist in system planning and design, system implementation plan preparation consultation, system feasibility report preparation consultation, system feasibility evaluation, etc. U application system scheme evaluation: in the demonstration of the application system construction scheme, the system architecture, reliability, scalability, compatibility, risk, investment cost and other contents of the scheme are evaluated in order to clarify the risk and feasibility of system construction and provide support for leaders' decision-making. At the same time, some improvement suggestions are given according to the shortcomings of the scheme. U application system cost estimation: estimate the cost of the application software in the system according to its scale, structure, technical content, etc., in order to provide reference for the project investment budget or final accounts. U comparison test: combined with the customer's system application planning, establish a unified test benchmark, benchmark the alternative products, issue an authoritative test report, and provide a quantitative basis for application system selection. 2) Information system construction and development carry out quality control in the process of information system construction and development, it can be divided into the following aspects: U requirements engineering consultation and stage review: participating in system requirements research and analysis, assisting in the construction of requirements management and development specifications, guidance of requirements analysis techniques and tools, etc.; review and verify the results of phased requirements analysis. Technical consultation and technical review of design and development: assist in the establishment of coding specifications, guidance of system analysis and design methods and tools, etc.; technical review and verification of the phased results of system design, and follow-up of the implementation of the specification, put forward feasible suggestions on the problems found and put forward improvement measures. U Software testing consultation and process testing: improve and build the software testing system, assist in the establishment of defect management specifications, and test and confirm the development products in all stages of the software development and implementation process. According to the software development contract or plan, carry out strict testing for all stages of the product, including unit testing, integration testing, system testing. U Technical review and quality assurance: technical review of work results, regular quality inspection of work results and provision of quality assurance reports; u Project management consulting: assist in the construction of project management specifications, application guidance of project management tools, etc. U configuration management consulting: assist in the construction of configuration management specifications, application guidance of configuration management tools, etc. U quality management consultation: assist in the construction of quality assurance specifications, application guidance of quality management tools, etc.; u Software process improvement consultation: build software process specifications, assist in the implementation of software process improvement. U document system consultation: assist in constructing the structure system of all kinds of project documents according to the actual situation of the project, and provide feasible document writing templates and cases. 3) Information system delivery and acceptance in the later stage of the software project, the trial operation of the software project shows that the software development and other work has been basically completed, at this time, you can start to prepare for the acceptance of the software project. Software development project acceptance is the evaluation of the results of the whole development project, and it is the process of evaluating, identifying and summarizing the project before software delivery, including cost, quality, service and other aspects. Through the acceptance work, to find out the problems and deficiencies that may exist in the project, and make the final correction, so that the project results can be delivered to the final users perfectly. U acceptance testing: strictly test the function, performance, reliability, ease of use, maintainability, portability and other characteristics of the software according to the contracts between software developers and users, the specification of software requirements and relevant industry standards, national standards, laws and regulations, etc., in order to find out the defects and deficiencies of the software, and improve the results of the project. U project cost evaluation: provide project cost assessment for users who need to audit and calculate the project cost, and give reference opinions on the cost of the software. U document testing: review the relevant documents provided by the software developer and propose modifications to facilitate the use, maintenance and migration of the software or system. U performance inspection: check the progress, services and other projects specified in the contract in order to protect the interests of both parties. 4) Information system operation and maintenance u application system risk assessment: a comprehensive evaluation of the overall situation of the application system, including the testing, evaluation and estimation of the function, reliability, performance, security, risk and input cost of the system, and some suggestions for improvement are given. U Information system performance testing and fault diagnosis: we use application system performance, server monitoring, network analysis and other tools to achieve network application fault location and management, analyze the distribution of response time of key applications in the client, network and server, summarize the throughput and network bandwidth occupancy of key applications, and reveal the real causes of application system failure.
