Software Quality Assurance
Software quality assurance (SQA) is a means and practice of monitoring all software engineering processes, methods, and work products to ensure compliance against defined standards. It may include ensuring conformance to standards or models, such as ISO/IEC 9126 (now superseded by ISO 25010), SPICE or CMMI. It includes standards and procedures that managers, administrators or developers may use to review and audit software products and activities to verify that the software meets quality criteria which link to standards. SQA encompasses the entire software development process, including requirements engineering, software design, coding, code reviews, source code control, software configuration management, testing, release management and software integration. It is organized into goals, commitments, abilities, activities, measurements, verification and validation. Purpose SQA involves a three-pronged approach: * Organization-wide policies, procedures and standar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Engineering
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining Application software, software applications. It involves applying engineering design process, engineering principles and computer programming expertise to develop software systems that meet user needs. The terms ''programmer'' and ''coder'' overlap ''software engineer'', but they imply only the construction aspect of a typical software engineer workload. A software engineer applies a software development process, which involves defining, Implementation, implementing, Software testing, testing, Project management, managing, and Software maintenance, maintaining software systems, as well as developing the software development process itself. History Beginning in the 1960s, software engineering was recognized as a separate field of engineering. The development of software engineering was seen as a struggle. Problems included software that was over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verification And Validation
Verification and validation (also abbreviated as V&V) are independent procedures that are used together for checking that a product, service, or system meets requirements and specification (technical standard), specifications and that it fulfills its intended purpose. These are critical components of a quality management system such as ISO 9000. The words "verification" and "validation" are sometimes preceded with "independent", indicating that the verification and validation is to be performed by a disinterested third party. "Independent verification and validation" can be abbreviated as "IV&V". In reality, as quality management terms, the definitions of verification and validation can be inconsistent. Sometimes they are even used interchangeably. However, A Guide to the Project Management Body of Knowledge, the PMBOK guide, a standard adopted by the Institute of Electrical and Electronics Engineers (IEEE), defines them as follows in its 4th edition: * "Validation.

Software Quality Management
Software Quality Management (SQM) is a management process that aims to develop and manage the quality of software in such a way so as to best ensure that the product meets the quality standards expected by the customer while also meeting any necessary regulatory and developer requirements, if any. Software quality managers require software to be tested before it is released to the market, and they do this using a cyclical process-based quality assessment in order to reveal and fix bugs before release. Their job is not only to ensure their software is in good shape for the consumer but also to encourage a culture of quality throughout the enterprise. Quality management activities Software quality management activities are generally split up into three core components: quality assurance, quality planning, and quality control. Some like software engineer and author Ian Sommerville don't use the term "quality control" (as quality control is often viewed as more a manufacturing term tha ...

Software Quality Analyst
A software quality assurance (QA) analyst, also referred to as a software quality analyst or simply a quality assurance (QA) analyst, is an individual who is responsible for applying the principles and practices of software quality assurance throughout the software development life cycle. Software testing is one of many parts of the larger process of QA. Testing is used to detect errors in a product, while QA also fixes the processes that resulted in those errors. Software QA analysts may have professional certification from a software testing certification board, like the International Software Testing Qualifications Board The International Software Testing Qualifications Board (ISTQB) is a software testing certification board that operates internationally. Founded in Edinburgh in November 2002, the ISTQB is a non-profit association legally registered in Belgium. I ... (ISTQB).

Quality By Design
Quality by design (QbD) is a concept first outlined by quality expert Joseph M. Juran in publications, most notably ''Juran on Quality by Design''. Designing for quality and innovation is one of the three universal processes of the Juran Trilogy, in which Juran describes what is required to achieve breakthroughs in new products, services, and processes. Juran believed that quality could be planned, and that most quality crises and problems relate to the way in which quality was planned. While quality by design principles have been used to advance product and process quality in industry, and particularly the automotive industry, they have also been adopted by the U.S. Food and Drug Administration (FDA) for the discovery, development, and manufacture of drugs. Juran on quality by design The Juran Trilogy defines the word "quality" as having two meanings: first, the presence of features that create customer satisfaction; second, the reliability of those features. Failures in feature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOD-STD-2167
DOD-STD-2167A (Department of Defense Standard 2167A), titled "Defense Systems Software Development", was a United States defense standard, published on February 29, 1988, which updated the less well known DOD-STD-2167 published 4 June 1985. This document established "uniform requirements for the software development that are applicable throughout the system life cycle." This revision was written to allow the contractor more flexibility and was a significant reorganization and reduction of the previous revision; ''e.g..'', where the previous revision prescribed pages of design and coding standards, this revision only gave one page of general requirements for the contractor's coding standards; while DOD-STD-2167 listed 11 quality factors to be addressed for each software component in the SRS, DOD-STD-2167A only tasked the contractor to address relevant quality factors in the SRS. Like DOD-STD-2167, it was designed to be used with DOD-STD-2168, "Defense System Software Quality Progr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Change Control Board
In software development, projects and programs, a change control board (CCB) is a committee that consists of Subject Matter Experts (''SME'', e.g. software engineers, testing experts, etc.) and Managers (e.g. Quality Assurance managers), who decide whether to implement proposed changes to a project. The main objective of a CCB is to ensure the client accepts the project. Factors affecting a CCB's decision can include the project's phase of development, budget, schedule, and quality goals. Change control (see Scope management) is also part of Requirements engineering. CCBs are most associated with the waterfall method of software development, but can be seen as having analogues in some implementations of Agile software development. The Change Control Board will review any proposed changes from the original baseline requirements that were agreed upon with the client. If any change is agreed upon by the committee, the change is communicated to the project team and the client, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scope (project Management)
In project management Project management is the process of supervising the work of a Project team, team to achieve all project goals within the given constraints. This information is usually described in project initiation documentation, project documentation, crea ..., scope is the defined features and functions of a product, or the scope of work needed to finish a project. Scope involves getting information required to start a project, including the features the product needs to meet its stakeholders' requirements. Project scope is oriented towards the work required and methods needed, while product scope is more oriented toward functional requirements. If requirements are not completely defined and described and if there is no effective change control in a project, scope or requirement creep may ensue. Scope management is the process of defining, and managing the scope of a project to ensure that it stays on track, within budget, and meets the expectations of stakeholde ...

Project Manager
A project manager is a professional in the field of project management. Project managers have the responsibility of the Project planning, planning, procurement and execution of a project, in any undertaking that has a defined scope, defined start and a defined finish; regardless of industry. Project managers are first point of contact for any issues or discrepancies arising from within the heads of various departments in an organization before the problem escalates to higher authorities, as project representative. Project management is the responsibility of a project manager. This individual seldom participates directly in the activities that produce the result, but rather strives to maintain the progress, mutual interaction and task (project management), tasks of various parties in such a way that reduces the risk of overall failure, maximizes benefits, and minimizes costs.

Model-driven Engineering
Model-driven engineering (MDE) is a software development methodology that focuses on creating and exploiting domain models, which are conceptual model (computer science), conceptual models of all the topics related to a specific problem. Hence, it highlights and aims at representation (mathematics), abstract representations of the Knowledge representation and reasoning, knowledge and activities that govern a particular domain (software engineering), application domain, rather than the computing (i.e. algorithmic) concepts. MDE is a subfield of a software design approach referred as round-trip engineering. The scope of the MDE is much wider than that of the model-driven architecture, Model-Driven Architecture. Overview The MDE approach is meant to increase productivity by maximizing compatibility between systems (via reuse of standardized models), simplifying the process of design (via models of recurring design patterns in the application domain), and promoting communication betw ...
