Release Management
Release management is the process of managing, planning, scheduling and controlling a software build through different stages and environments; it includes testing and deploying software releases. Relationship with processes Organizations that have adopted agile software development are seeing much higher quantities of releases. With the increasing popularity of agile development a new approach to software releases known as continuous delivery is starting to influence how software transitions from development to a release. One goal of continuous delivery and DevOps is to release more reliable applications faster and more frequently. The movement of the application from a "build" through different environments to production as a "release" is part of the continuous delivery pipeline. Release managers are beginning to utilize tools such as application release automation and continuous integration tools to help advance the process of continuous delivery and incorporate a culture o ...

Software Release
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. Pre-alpha refers to the early stages of development, when the software is still being designed and built. Alpha testing is the first phase of formal testing, during which the software is tested internally using white-box techniques. Beta testing is the next phase, in which the software is tested by a larger group of users, typically outside of the organization that developed it. The beta phase is focused on reducing impacts on users and may include usability testing. After beta testing, the software may go through one or more release candidate phases, in which it is refined and tested further, before the final version is released. Some software, particularly in the internet and technolo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Agile Software Development
Agile software development is an umbrella term for approaches to software development, developing software that reflect the values and principles agreed upon by ''The Agile Alliance'', a group of 17 software practitioners, in 2001. As documented in their ''Manifesto for Agile Software Development'' the practitioners value: * Individuals and interactions over processes and tools * Working software over comprehensive documentation * Customer collaboration over contract negotiation * Responding to change over following a plan The practitioners cite inspiration from new practices at the time including extreme programming, Scrum (software development), scrum, dynamic systems development method, adaptive software development and being sympathetic to the need for an alternative to documentation driven, heavyweight software development processes. Many software development practices emerged from the agile mindset. These agile-based practices, sometimes called ''Agile'' (with a capital ...

Continuous Delivery
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 Poka-Yoke: a set of validations through which a piece of software must pass on its way to release. Code is compiled if necessary and then packaged by a build server every time a change is committed to a source control repository, then teste ...

DevOps
DevOps is the integration and automation of the software development and information technology operations. DevOps encompasses necessary tasks of software development and can lead to shortening development time and improving the development life cycle. According to Neal Ford, DevOps, particularly through continuous delivery, employs the "Bring the pain forward" principle, tackling tough tasks early, fostering automation and swift issue detection. Software programmers and architects should use fitness functions to keep their software in check. Although debated, DevOps is characterized by key principles: shared ownership, workflow automation, and rapid feedback. From an academic perspective, Len Bass, Ingo Weber, and Liming Zhu—three computer science researchers from the CSIRO and the Software Engineering Institute—suggested defining DevOps as "a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal produ ...

Application Release Automation
Application-release automation (ARA) refers to the process of packaging and deploying an application or update of an application from development, across various environments, and ultimately to production. ARA solutions must combine the capabilities of deployment automation, environment management and modeling, and release coordination. Relationship with DevOps ARA tools help cultivate DevOps best practices by providing a combination of automation, environment modeling and workflow-management capabilities. These practices help teams deliver software rapidly, reliably and responsibly. ARA tools achieve a key DevOps goal of implementing continuous delivery 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.

Continuous Integration
Continuous integration (CI) is the practice of integrating source code changes frequently and ensuring that the integrated codebase is in a workable state. Typically, developers Merge (version control), merge changes to an Branching (revision control), integration branch, and an automated system Software build, builds and software testing, tests the software system. Often, the automated process runs on each Commit (version control), commit or runs on a schedule such as once a day. Grady Booch first proposed the term CI in Booch method, 1991, although he did not advocate integrating multiple times a day, but later, CI came to include that aspect. History The earliest known work (1989) on continuous integration was the Infuse environment developed by G. E. Kaiser, D. E. Perry, and W. M. Schell. In 1994, Grady Booch used the phrase continuous integration in ''Object-Oriented Analysis and Design with Applications'' (2nd edition) to explain how, when developing using micro ...

IT Service Management
Information technology service management (ITSM) are the activities performed by an organization to design, build, deliver, operate and control IT services offered to customers. Differing from more technology-oriented IT management approaches like network management and IT systems management, IT service management is characterized by adopting a process approach towards management, focusing on customer needs and IT services for customers rather than IT systems, and stressing continual improvement. The CIO WaterCooler's 2017 ITSM report states that business uses ITSM "mostly in support of customer experience (35%) and service quality (48%)." Process Execution of ITSM processes in an organization, especially those processes that are more workflow-driven, can benefit significantly from being supported with specialized software tools. Service desk A service desk is a primary IT function within the discipline of IT service management (ITSM) as defined by ITIL. It is inten ...

Management Fad
Management (or managing) is the administration of organizations, whether businesses, nonprofit organizations, or a government bodies through business administration, nonprofit management, or the political science sub-field of public administration respectively. It is the process of managing the resources of businesses, governments, and other organizations. Larger organizations generally have three hierarchical levels of managers, organized in a pyramid structure: * Senior management roles include the board of directors and a chief executive officer (CEO) or a president of an organization. They set the strategic goals and policy of the organization and make decisions on how the overall organization will operate. Senior managers are generally executive-level professionals who provide direction to middle management. Compare governance. * Middle management roles include branch managers, regional managers, department managers, and section managers. They provide direction to f ...

ITIL
ITIL (previously and also known as Information Technology Infrastructure Library) is a framework with a set of practices (previously processes) for IT activities such as IT service management (ITSM) and IT asset management (ITAM) that focus on aligning IT services with the needs of the business. ITIL describes best practices, including processes, procedures, tasks, and checklists which are neither organization-specific nor technology-specific. It is designed to allow organizations to establish a baseline and can be used to demonstrate compliance and to measure improvements. There is no formal independent third-party compliance assessment available to demonstrate ITIL compliance in an organization. Certification in ITIL is only available to individuals and not organizations. Since 2021, the ITIL trademark has been owned by PeopleCert. History Responding to growing dependence on IT, the UK Government's Central Computer and Telecommunications Agency (CCTA) in the 1980s develo ...

Software Project Management
Software project management is the process of planning and leading software projects. It is a sub-discipline of project management in which software projects are planned, implemented, monitored and controlled. History In the 1970s and 1980s, the software industry grew very quickly, as computer companies quickly recognized the relatively low cost of software production compared to hardware production and circuitry. To manage new development efforts, companies applied the established project management methods, but project schedules slipped during test runs, especially when confusion occurred in the gray zone between the user specifications and the delivered software. To be able to avoid these problems, ''software'' project management methods focused on matching user requirements to delivered products, in a method known now as the waterfall model. As the industry has matured, analysis of software project management failures has shown that the following are the most common caus ...

Version Control
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file. Version control is a component of software configuration management. A ''version control system'' is a software tool that automates version control. Alternatively, version control is embedded as a feature of some systems such as word processors, spreadsheets, collaborative groupware, web docs, and content management systems, e.g., Help:Page history, Wikipedia's page history. Version control includes viewing old versions and enables Reversion (software development), reverting a file to a previous version. Overview As teams develop software, it is common to Software deployment, deploy multiple versions of the same software, and for different developers to work on one or more different versions ...
