Deployment Pipeline
Continuous delivery (CD) is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software with greater speed and frequency. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production. A straightforward and repeatable deployment process is important for continuous delivery. Principles According to Neal Ford, continuous delivery adopts "Bring the pain forward," tackling tough tasks early, fostering automation and swift issue detection. Continuous delivery treats the commonplace notion of a ''deployment pipeline'' as a lean software development, lean Poka-Yoke: a set of validations through which a piece of software must pass on its way to software release, release. Code is compiled if necessary and then packaged by a build server every time a change is committed ... [...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] |
Architecturally Significant Requirements
Architecturally significant requirements are those requirements that have a measurable effect on a computer system’s architecture. This can comprise both software and hardware requirements. They are a subset of requirements that affect a system architecture in measurably identifiable ways. Relation to non-functional requirements and quality attributes Architecturally significant requirements were only recently, as of 2016, recognized as an important notion. When discussing architecture, the terms non-functional requirements or quality attributes are often used. However, recent empirical studies show that, for a software system, not all non-functional requirements affect its architecture, and functional requirements can also affect its architecture. This research suggests distinguishing which software requirements are architecturally significant and whether they are functional when discussing software architecture is worth it. Characteristics Architecturally significant requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CI/CD
In software engineering, CI/CD or CICD is the combined practices of continuous integration (CI) and continuous delivery (CD) or, less often, continuous deployment. They are sometimes referred to collectively as continuous development or continuous software development. Components ;Continuous integration: Frequent merging of several small changes into a main branch. ; Continuous delivery: Producing software in short cycles with high speed and frequency so that reliable software can be released at any time, with a simple and repeatable deployment process when deciding to deploy. ; Continuous deployment: Automatic rollout of new software functionality. When these three processes occur in order, they may be described as a "CI/CD pipeline". Motivation CI/CD bridges the gaps between development and operation activities and teams by enforcing automation in building, testing and deployment of applications. CI/CD services compile the incremental code changes made by developers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Test Oracle
In software testing, a test oracle (or just oracle) is a provider of information that describes correct output based on the input of a test case. Testing with an oracle involves comparing actual results of the system under test (SUT) with the expected results as provided by the oracle. The term "test oracle" was first introduced in a paper by William E. Howden. Additional work on different kinds of oracles was explored by Elaine Weyuker. An oracle can operate separately from the SUT; accessed at test runtime, or it can be used before a test is run with expected results encoded into the test logic.Jalote, Pankaj; ''An Integrated Approach to Software Engineering'', Springer/Birkhäuser, 2005, However, method postconditions are part of the SUT, as automated oracles in design by contract models. Determining the correct output for a given input (and a set of program or system states) is known as the ''oracle problem'' or ''test oracle problem'', which some consider a relatively ...

Customer Satisfaction
Customer satisfaction is a term frequently used in marketing to evaluate customer experience. It is a measure of how products and services supplied by a company meet or surpass customer expectation. Customer satisfaction is defined as "the number of customers, or percentage of total customers, whose reported experience with a firm, its products, or its services (ratings) exceeds specified Contentment, satisfaction goals".. Enhancing customer satisfaction and fostering customer loyalty are pivotal for businesses, given the significant importance of improving the balance between customer Attitude (psychology), attitudes before and after the consumption process. Expectation confirmation theory, Expectancy disconfirmation theory is the most widely accepted theoretical framework for explaining customer satisfaction. However, other frameworks, such as equity theory, attribution theory, Contrast theory of meaning, contrast theory, assimilation theory, and various others, are also used to ...

Product Quality
In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or superiority of something (goods or services); it is also defined as being suitable for the intended purpose (fitness for purpose) while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace. Producers might measure the conformance quality, or degree to which the product/service was produced correctly. Support personnel may measure quality in the degree that a product is reliable, maintainable, or sustainable. In such ways, the subjectivity of quality is rendered objective via operational definitions and measured with metrics such as proxy measures. In a general manner, quality in business consists of "producing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time To Market
In commerce, time to market (TTM) is the length of time it takes from a product being conceived until its being available for sale. The reason that time to market is so important is that being late erodes the addressable market into which producers have to sell their product. A common assumption is that TTM matters most for first-of-a-kind products, but actually a late product launch in any industry can negatively impact revenues—from reducing the window of opportunity to generate revenues to causing the product to become obsolete faster. Measuring TTM There are no standards for measuring TTM, and measured values can vary greatly. First, there is great variation in how different organizations define the start of the period. For example, in the automotive industry the development period starts when the product concept is approved. Other organizations realize that little will happen until the project is staffed, which can take a long time after approval if developers are tied u ...
