Work on Codes and Guides was initiated in 1975 in five main fields: govern- ment organization, siting, design, operation and quality assurance. In the field of quality assurance the Code of Practice and ten Safety Guides had been developed by 1986 and published in English, French, Spanish and Russian, as well as some in Chinese. These documents are now used in a number of Member States as quality assurance requirements for nuclear power plants. To facilitate the use of these publications, the IAEA Technical Review Committee on Quality Assurance has stressed on a number of occasions the need for and importance of proceeding with the development of User's Manuals. These documents should provide Member States implementing the Code and the Safety Guides with practical examples of procedures, practices and documents illustrating the quality assurance methods and techniques used in those organizations in Member States which have broad experience in quality assurance. The same opinion was expressed in the discussions during the International Symposium on Quality Assurance for Nuclear Power Plants organized by the IAEA and held in Paris in May 1981. A number of topics have been identified for which User's Manuals could provide additional information and facilitate correct implementation of the Code and Guides in nuclear power plant project activities. To implement these recommendations, work has been initiated in the Secretariat to develop those User's Manuals which are most needed in Member States embarking on nuclear power programmes and starting quality assurance activities. Keeping in mind the difference between User's Manuals and Codes and Safety Guides, work on the development of these documents is undertaken outside the NUSS Programme and the established procedures for development, review and approval of the documents used in this Programme. For User's Manuals it was decided to follow the standard practices used in the development of other Agency publications such as Guidebooks and Technical Reports. This procedure will reduce the time and cost of preparation of User's Manuals, which are the lower levels in the hierarchy of NUSS Programme documents and do not contain requirements for whose formulation a broad consensus of quality assurance experts would be needed. The present Manual on Quality Assurance for Computer Software Related to the Safety of Nuclear Power Plants provides guidance in the assurance of quality of specification, design, implementation, maintenance and use of computer software related to items and activities important to safety in nuclear power plants. This guidance is consistent with, and supplements, the requirements and recommenda- tions of Quality Assurance for Safety in Nuclear Power Plants: A Code of Practice, 50-C-QA, and related Safety Guides on quality assurance for nuclear power plants. The Manual is intended to be of use to all those who, in any way, are involved with software for safety related applications for nuclear power plants, including auditors who may be called upon to audit management systems and product software.

  • Writing Quality Software

    Writing Quality Software

    Writing Quality Software About this white paper: This whitepaper was written by David C. Young, an employee of General Dynamics Information Technology (GDIT). Dr. Young is part of a team of GDIT employees who maintain, and support high performance computing systems at the Alabama Supercomputer Center (ASC). This was written in 2020. This paper is written for people who want to write good software, but don’t have a master’s degree in software architecture (or someone managing the project who does). Much of what is here would be covered in a software development practices class, often taught at the master’s degree level. Writing quality software is not only about the satisfaction of a job well done. It is also reflects on you and your professional reputation amongst your peers. In some cases writing quality software can be a factor in getting a job, losing a job, or even life or death. Furthermore, writing quality software should be considered an implicit requirement in every software development project. If the intended useful life of the software is many years, that is yet another reason to do a good job writing it. Introduction Consider this situation, which is all too common. You have written a really neat piece of software. You put it out on github, then tell your colleagues about it. Soon you are bombarded with a series of complaints from people who tried to install, and use your software. Some of those complaints might be; • It won’t install on their version of Linux. • They did the same thing you reported, but got a different answer.

    Studying the Feasibility and Importance of Software Testing: an Analysis

    Dr. S.S.Riaz Ahamed / Internatinal Journal of Engineering Science and Technology Vol.1(3), 2009, 119-128 STUDYING THE FEASIBILITY AND IMPORTANCE OF SOFTWARE TESTING: AN ANALYSIS Dr.S.S.Riaz Ahamed Principal, Sathak Institute of Technology, Ramanathapuram,India. Email:[email protected], [email protected] ABSTRACT Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. Software testing is the process of testing the functionality and correctness of software by running it. Software testing is usually performed for one of two reasons: defect detection, and reliability estimation. The problem of applying software testing to defect detection is that software can only suggest the presence of flaws, not their absence (unless the testing is exhaustive). The problem of applying software testing to reliability estimation is that the input distribution used for selecting test cases may be flawed. The key to software testing is trying to find the modes of failure - something that requires exhaustively testing the code on all possible inputs. Software Testing, depending on the testing method employed, can be implemented at any time in the development process. Keywords: verification and validation (V & V) 1 INTRODUCTION Testing is a set of activities that could be planned ahead and conducted systematically. The main objective of testing is to find an error by executing a program. The objective of testing is to check whether the designed software meets the customer specification. The Testing should fulfill the following criteria: ¾ Test should begin at the module level and work “outward” toward the integration of the entire computer based system.

These bottlenecks include finding and setting up test environments, test configurations, and test results implementation. These issues are not industry specific. They can be experienced in manufacturing, service businesses, and governments alike. They can be reduced by having a thorough understanding and a disciplined, mature implementation of Continuous Testing and related recommended engineering practices. The best place to start addressing these challenges is having a good understanding of what Continuous Testing is. Marc Hornbeek, the author of Engineering DevOps, describes it as: “A quality assessment strategy in which most tests are automated and integrated as a core and essential part of DevOps. Continuous Testing is much more than simply ‘automating tests.’” In this whitepaper, we’ll address the best practices you can adopt for implementing Continuous Quality and Testing on the AWS Cloud environment in the context of the DevOps model.
