Software Requirements
Software requirements for a system are the description of what the system should do, the service or services that it provides and the constraints on its operation. The IEEE Standard Glossary of Software Engineering Terminology defines a requirement as: # A condition or Capability (systems engineering), capability needed by a user to solve a problem or achieve an objective # A condition or capability that must be met or possessed by a system or system component to satisfy a contract, standard, specification, or other formally imposed document # A documented representation of a condition or capability as in 1 or 2 The activities related to working with software requirements can broadly be broken down into elicitation, analysis, specification, and management. Note that the wording ''Software requirements'' is additionally used in software release notes to explain, which depending on Package_(package_management_system), software packages are required for a certain software to be built ...

Requirement
In engineering, a requirement is a condition that must be satisfied for the output of a work effort to be acceptable. It is an explicit, objective, clear and often quantitative description of a condition to be satisfied by a material, design, product, or service. A specification or spec is a set of requirements that is typically used by developers in the design stage of new product development, product development and by testers in their verification process. With iterative and incremental development such as agile software development, requirements are developed in parallel with design and implementation. With the waterfall model, requirements are completed before design or implementation start. Requirements are used in many engineering fields including engineering design, system engineering, software engineering, enterprise engineering, New product development, product development, and process optimization. Requirement is a relatively broad concept that can describe any nec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mind Mapping
A mind map is a diagram used to visually organize information into a hierarchy, showing relationships among pieces of the whole. It is often based on a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those major ideas. Mind maps can also be drawn by hand, either as "notes" during a lecture, meeting or planning session, for example, or as higher quality pictures when more time is available. Mind maps are considered to be a type of spider diagram. Origin Although the term "mind map" was first popularized by British popular psychology author and television personality Tony Buzan, the use of diagrams that visually "map" information using branching and radial maps traces back centuries. These pictorial methods record knowledge and model systems, and have a long history in lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unified Modeling Language
The Unified Modeling Language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure diagrams. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. In 1997, UML was adopted as a standard by the Object Management Group (OMG) and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as the ISO/IEC 19501 standard. Since then the standard has been periodically revised to cover the latest revision of UML. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Requirements Interchange Format
RIF/ReqIF (Requirements Interchange Format) is an Extensible Markup Language, XML file format that can be used to exchange requirements, along with its associated metadata, between software tools from different vendors. The requirements exchange format also defines a workflow for transmitting the status of requirements between partners. Although developed in the automotive industry, ReqIF is suitable for lossless exchange of requirements in any industry. History In 2004, HIS (Herstellerinitiative Software) a consortium of German automotive manufacturers, defined a generic requirements interchange format called RIF. The format was handed over in 2008 to ProSTEP iViP, ProSTEP iViP e.V. for further maintenance. A project group responsible for international standardization further developed the format and handed over a revised version to Object Management Group (OMG) as "Request for Comment" in 2010. As the acronym RIF had an ambiguous meaning within the OMG, the new name ReqIF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Requirements Specification
A software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction. Software requirements specifications establish the basis for an agreement between customers and contractors or suppliers on how the software product should function (in a market-driven project, these roles may be played by the marketing and development divisions). Software requirements specification is a rigorous assessment of requirements before the more specific system design stages, and its goal is to reduce later redesign. It should also provide a realistic basis for estimating product costs, risks, and schedules. Used appropriately, software requirements specifications can he ...

Trello
Trello is a web-based, kanban-style, list-making application developed by Atlassian. Created in 2011 by Fog Creek Software, it was spun out to form the basis of a separate company in New York City in 2014 and sold to Atlassian in January 2017. History The name ''Trello'' is derived from the word ''trellis'', which had been a code name for the project at its early stages. Trello was released at a TechCrunch event by Fog Creek founder Joel Spolsky. In September 2011 ''Wired'' magazine named the application one of "The 7 Coolest Startups You Haven't Heard of Yet". Lifehacker said "it makes project collaboration simple and kind of enjoyable". In 2014, it raised US$10.3 million in funding from Index Ventures and Spark Capital. Prior to its acquisition, Trello had sold 22% of its shares to investors, with the remaining shares held by founders Michael Pryor and Joel Spolsky. In May 2016, Trello claimed it had more than 1.1 million daily active users and 14 million tot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collaboration Tool
A collaboration tool helps people to collaborate. The purpose of a collaboration tool is to support a group of two or more individuals to accomplish a common goal or objective. Collaboration tools can be either of a non-technological nature such as paper, flipcharts, post-it notes or whiteboards. They can also include software tools and applications such as collaborative software. Early computer-based collaboration tools The first idea to use computers in order to work with each other was formed in 1945 when Vannevar Bush shared his thoughts on a system he named "memex" in his article "As We May Think". A system that stores books, records and communications of an individual and makes them available at any time. At this stage he called it "''an enlarged supplement to his memory"''. Computerized office automation In 1968 computer systems were brought in connection with communication and the potential way of working together when not at the same place by Dr. J. C. R. Licklide ...

Wiki
A wiki ( ) is a form of hypertext publication on the internet which is collaboratively edited and managed by its audience directly through a web browser. A typical wiki contains multiple pages that can either be edited by the public or limited to use within an organization for maintaining its internal knowledge base. Its name derives from the first user-editable website called " WikiWikiWeb," with "wiki" being a Hawaiian word meaning "quick." Wikis are powered by wiki software, also known as wiki engines. Being a form of content management system, these differ from other web-based systems such as blog software or static site generators in that the content is created without any defined owner or leader. Wikis have little inherent structure, allowing one to emerge according to the needs of the users. Wiki engines usually allow content to be written using a lightweight markup language and sometimes edited with the help of a rich-text editor. There are dozens of differ ...

Concordion
Concordion is a specification by example framework originally developed by David Peterson, and now maintained by a team of contributors, led by Nigel Charman. Inspired by the Fit Framework, David states the following aims were behind Concordion: * Improved readability of documents * More "opinionated" (scripting is actively discouraged) * Easier to use How it works Concordion specifications are written in Markdown, HTML or Excel and then instrumented with special links, attributes or comments respectively. When the corresponding test fixture class is run, Concordion interprets the instrumentation to execute the test. Rather than forcing product owners to specify requirements in a specially structured language, Concordion lets you write them in normal language using paragraphs, tables and proper punctuation. This makes the specifications much more natural to read and write, and helps everyone to understand and agree about what a feature is supposed to do. The Markdown, HTML ...

Specification By Example
Specification by example (SBE) is a collaborative approach to defining requirements and business-oriented functional tests for software products based on capturing and illustrating requirements using realistic examples instead of abstract statements. It is applied in the context of agile software development methods, in particular behavior-driven development. This approach is particularly successful for managing requirements and functional tests on large-scale projects of significant domain and organisational complexity. Specification by example is also known as example-driven development, executable requirements, acceptance test–driven development (ATDD or A-TDD), Agile Acceptance Testing, Test-Driven Requirements (TDR). Advantages Highly abstract or novel new concepts can be difficult to understand without concrete examples. Specification by example is intended to construct an accurate understanding, and significantly reduces feedback loops in software development, leading ...

FreeMind
FreeMind is a free mind mapping application written in Java, which is further developed by the fork Freeplane. FreeMind itself was last updated in 2014. FreeMind is licensed under the GNU General Public License Version 2. It provides extensive export capabilities. It runs on Microsoft Windows, Linux, and macOS via the Java Runtime Environment. As with other mind mapping software packages, FreeMind allows the user to edit a hierarchical set of ideas around a central concept. The non-linear approach assists in brainstorming new outlines and projects as ideas are added around the mind map. As a Java application, FreeMind is portable across multiple platforms and retains the same user interface, causing some amount of variation from the common interface on each platform. Mac users may notice the most difference from their traditional user interface, but a MacWorld reviewer says the software's features should still appeal to the segment of users who accept function over form. ...
