DevOps Research And Assessment
''DevOps Research and Assessment'' (abbreviated to DORA) is a team that is part of Google Cloud that engages in opinion polling of software engineers to conduct research for the DevOps movement. The DORA team was founded by Nicole Forsgren, Jez Humble and Gene Kim. and conducted research for the DevOps company Puppet and later became an independent team (with Puppet continuing to produce reports by a new team). Whilst the founding members have departed, the DORA team continue to publish research in the form of annual ''State of DevOps Reports''. State of DevOps Reports The DORA team began publishing State of DevOps Reports in 2013. The latest DORA State of DevOps Report, published in 2024, surveyed "more than 39,000 professionals across many industries globally." It found AI is having a broad impact on software development, with largely positive results. "Flow," "productivity," and "job satisfaction" are cited among 8 benefits of AI adoption for software developers. The detri ...

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 ...

Rapid Application Development
Rapid application development (RAD), also called rapid application building (RAB), is both a general term for adaptive software development approaches, and the name for James Martin's method of rapid development. In general, RAD approaches to software development put less emphasis on planning and more emphasis on an adaptive process. Prototypes are often used in addition to or sometimes even instead of design specifications. RAD is especially well suited for (although not limited to) developing software that is driven by user interface requirements. Graphical user interface builders are often called rapid application development tools. Other approaches to rapid development include the adaptive, agile, spiral, and unified models. History Rapid application development was a response to plan-driven waterfall processes, developed in the 1970s and 1980s, such as the Structured Systems Analysis and Design Method (SSADM). One of the problems with these methods is that they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunk-based Development
Branching, in version control and software configuration management, is the duplication of an object under version control (such as a source code file or a directory tree). Each object can thereafter be modified separately and in parallel so that the objects become different. In this context the objects are called branches. The users of the version control system can branch any branch. Branches are also known as ''trees'', ''streams'' or ''codelines''. The originating branch is sometimes called the ''parent branch'', the ''upstream branch'' (or simply ''upstream'', especially if the branches are maintained by different organizations or individuals), or the ''backing stream''. Trunk ''Child branches'' are branches that have a parent; a branch without a parent is referred to as the ''trunk'' or the ''mainline''. The trunk is also sometimes loosely referred to as HEAD, but properly head refers not to a branch, but to the most recent commit on a given branch, and both the trunk and ea ...

Lean Software Development
Lean software development is a translation of lean manufacturing principles and practices to the software development domain. Adapted from the Toyota Production System, it is emerging with the support of a pro-lean subculture within the agile community. Lean offers a solid conceptual framework, values and principles, as well as good practices, derived from experience, that support agile organizations. Origin The expression "lean software development" originated in a book by the same name, written by Mary Poppendieck and Tom Poppendieck in 2003. The book restates traditional lean principles, as well as a set of 22 ''tools'' and compares the tools to corresponding agile practices. The Poppendiecks' involvement in the agile software development community, including talks at several Agile conferences has resulted in such concepts being more widely accepted within the agile community. Lean principles Lean development can be summarized by seven principles, very close in ... [...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] |
Shingo Prize
The ''Shingo Prize for Organizational Excellence'' is an award for organizational excellence given to organizations worldwide by the Shingo Institute, part of the Jon M. Huntsman School of Business at Utah State University in Logan, Utah. In order to be selected as a recipient of the Shingo Prize, an organization "challenges" or applies for the award by first submitting an achievement report that provides data about recent business improvements and accomplishments and then undergoing an onsite audit performed by Shingo Institute examiners. Organizations are scored relative to how closely their culture matches the ideal as defined by the ''Shingo Model''™. Organizations that meet the criteria are awarded the Shingo Prize. Other awards include the Shingo Silver Medallion, the Shingo Bronze Medallion, the Research Award, and the Publication Award. History of the Shingo Prize Beginnings: 1988–2000 In 1988, Utah State University conferred an honorary doctorate to Shigeo Shingo, a J ...

Correlation Does Not Imply Causation
The phrase "correlation does not imply causation" refers to the inability to legitimately deduce a cause-and-effect relationship between two events or variables solely on the basis of an observed association or correlation between them. The idea that "correlation implies causation" is an example of a questionable-cause logical fallacy, in which two events occurring together are taken to have established a cause-and-effect relationship. This fallacy is also known by the Latin phrase ''cum hoc ergo propter hoc'' ('with this, therefore because of this'). This differs from the fallacy known as '' post hoc ergo propter hoc'' ("after this, therefore because of this"), in which an event following another is seen as a necessary consequence of the former event, and from conflation, the errant merging of two events, ideas, databases, etc., into one. As with any logical fallacy, identifying that the reasoning behind an argument is flawed does not necessarily imply that the resulting c ...

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 ...

British Post Office Scandal
The British Post Office scandal, also called the Horizon IT scandal, involved the Post Office pursuing thousands of innocent subpostmasters for apparent financial shortfalls caused by faults in Horizon, an accounting software system developed by Fujitsu. Between 1999 and 2015, more than 900 subpostmasters were convicted of theft, fraud and false accounting based on faulty Horizon data, with about 700 of these prosecutions carried out by the Post Office. Other subpostmasters were prosecuted but not convicted, forced to cover shortfalls—caused by Horizon—with their own money, or had their contracts terminated. The court cases, criminal convictions, imprisonments, loss of livelihoods and homes, debts, and bankruptcies led to stress, illness, family breakdowns and at least four suicides. In 2024, Prime Minister Rishi Sunak described the scandal as one of the greatest miscarriages of justice in British history. Although many subpostmasters had reported problems with the new soft ...
