Defect Criticality
In the context of software quality, defect criticality is a measure of the impact of a software defect. It is defined as the product of severity, likelihood, and class. Defects are different from user stories, and therefore the priority (severity) should be calculated as follows. Severity/impact * 0 - Affects critical data or functionality and leaves users with no workaround * 1 - Affects critical data or functionality and forces users to employ a workaround * 2 - Affects non-critical data or functionality and forces users to employ a workaround * 3 - Affects non-critical data or functionality and does not force users to employ a workaround * 4 - Affects aesthetics, professional look and feel, “quality” or “usability” Likelihood/visibility * 1 - Seen by all or almost all users who use the application (>=95% of users) * 2 - Seen by more than 2/3 of the users who use the application (>67% and 33% and 0% and <32%) Class of defect Class 0 |
Software Quality
In the context of software engineering, software quality refers to two related but distinct notions: * Software's functional quality reflects how well it complies with or conforms to a given design, based on functional requirements or specifications. That attribute can also be described as the fitness for the purpose of a piece of software or how it compares to competitors in the marketplace as a worthwhile product. It is the degree to which the correct software was produced. * Software structural quality refers to how it meets non-functional requirements that support the delivery of the functional requirements, such as robustness or maintainability. It has a lot more to do with the degree to which the software works as needed. Many aspects of structural quality can be evaluated only statically through the analysis of the software's inner structure, its source code (see Software metrics), at the unit level, and at the system level (sometimes referred to as end-to-end testin ...

User Story
In software development and product management, a user story is an informal, natural language description of features of a software system. They are written from the perspective of an end user or user of a system, and may be recorded on index cards, Post-it notes, or digitally in specific management software. Depending on the product, user stories may be written by different stakeholders like client, user, manager, or development team. User stories are a type of boundary object. They facilitate sensemaking and communication; and may help software teams document their understanding of the system and its context. History * 1997: Kent Beck introduces user stories at the Chrysler C3 project in Detroit. * 1998: Alistair Cockburn visited the C3 project and coined the phrase "A user story is a promise for a conversation." * 1999: Kent Beck published the first edition of the book ''Extreme Programming Explained'', introducing Extreme Programming (XP), and the usage of user stori ...

Usability
Usability can be described as the capacity of a system to provide a condition for its users to perform the tasks safely, effectively, and efficiently while enjoying the experience. In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use. The object of use can be a software application, website, book, tool, machine, process, vehicle, or anything a human interacts with. A usability study may be conducted as a primary job function by a ''usability analyst'' or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer. Usability includes methods of measuring usability, such as needs analysis and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reliability (statistics)
In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 (much error) and 1.00 (no error), are usually used to indicate the amount of error in the scores. For example, measurements of people's height and weight are often extremely reliable.The Marketing Accountability Standards Board (MASB) endorses this definition as part of its ongoinCommon Language: Marketing Activities and Metrics Pr ...

Testability
Testability is a primary aspect of science and the scientific method. There are two components to testability: #Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. #The practical feasibility of observing a reproducible series of such counterexamples if they do exist. In short, a hypothesis is testable if there is a possibility of deciding whether it is true or false based on experimentation by anyone. This allows anyone to decide whether a theory can be supported or refuted by data. However, the interpretation of experimental data may be also inconclusive or uncertain. Karl Popper introduced the concept that scientific knowledge had the property of falsifiability as published in '' The Logic of Scientific Discovery''.Karl Popper "The Logic of Scientific Discovery", 1934 (as ''Logik der Forschung'', English translation 1959), ISBN 0415278449 and 2002 ISBN 9780415278447, 0415278449 See also * Confirmability * Controlla ...

Data Loss
Data loss is an error condition in information systems in which information is destroyed by failures (like failed spindle motors or head crashes on hard drives) or neglect (like mishandling, careless handling or storage under unsuitable conditions) in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss or restore lost data. Data loss can also occur if the physical medium containing the data is lost or stolen. Data loss is distinguished from data unavailability, which may arise from a network outage. Although the two have substantially similar consequences for users, data unavailability is temporary, while data loss may be permanent. Data loss is also distinct from data breach, an incident where data falls into the wrong hands, although the term data loss has been used in those incidents.

Calculation
A calculation is a deliberate mathematical process that transforms a plurality of inputs into a singular or plurality of outputs, known also as a result or results. The term is used in a variety of senses, from the very definite arithmetical calculation of using an algorithm, to the vague heuristics of calculating a strategy in a competition, or calculating the chance of a successful relationship between two people. For example, multiplying 7 by 6 is a simple algorithmic calculation. Extracting the square root or the cube root of a number using mathematical models is a more complex algorithmic calculation. Statistical estimations of the likely election results from opinion polls also involve algorithmic calculations, but produces ranges of possibilities rather than exact answers. To ''calculate'' means to determine mathematically in the case of a number or amount, or in the case of an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols then they are capable of communicating with each other and they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Low-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all ...

Grammaticality
In linguistics, grammaticality is determined by the conformity to language usage as derived by the grammar of a particular speech variety. The notion of grammaticality rose alongside the theory of generative grammar, the goal of which is to formulate rules that define well-formed, grammatical sentences. These rules of grammaticality also provide explanations of ill-formed, ungrammatical sentences. In theoretical linguistics, a speaker's judgement on the well-formedness of a linguistic 'string'—called a grammaticality judgement—is based on whether the sentence is interpreted in accordance with the rules and constraints of the relevant grammar. If the rules and constraints of the particular lect are followed, then the sentence is judged to be grammatical. In contrast, an ungrammatical sentence is one that violates the rules of the given language variety. Linguists use grammaticality judgements to investigate the syntactic structure of sentences. Generative linguists are larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesthetics
Aesthetics (also spelled esthetics) is the branch of philosophy concerned with the nature of beauty and taste (sociology), taste, which in a broad sense incorporates the philosophy of art.Slater, B. H.Aesthetics ''Internet Encyclopedia of Philosophy,'' , accessed on 15 September 2024. Aesthetics examines values about, and Critical thinking, critical judgments of, artistic taste and preference. It thus studies how Artist, artists imagine, create, and perform works of art, as well as how people use, enjoy, and criticize art. Aesthetics considers why people consider certain things beautiful and not others, as well as how objects of beauty and art can affect our moods and our beliefs. Aesthetics tries to find answers to what exactly is art and what makes good art. It considers what happens in our minds when we view Visual arts, visual art, listen to music, read poetry, enjoy delicious food, and engage in large artistic projects like creating and experiencing plays, fashion shows ...

Software Bugs
A software bug is a design defect ( bug) in computer software. A computer program with many or serious bugs may be described as ''buggy''. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing). In 2002, a study commissioned by the US Department of Commerce's National Institute of Standards and Technology concluded that "software bugs, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product". Since the 1950s, some computer systems have been designed to detect or auto-correct various software errors during operations. History Terminology ''Mistake metamorphism'' (from Greek ''meta'' = "change", ''morph'' = "form") refers to the evolution of a defect in the final stage of software deployment. Transformation of a ''mistake'' committed by an analyst in the early stages of the softwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
