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] |
Adaptive Software Development
Adaptive software development (ASD) is a software development process that grew out of the work by Jim Highsmith and Sam Bayer on rapid application development (RAD). It embodies the principle that continuous adaptation of the process to the work at hand is the normal state of affairs. Adaptive software development replaces the traditional waterfall cycle with a repeating series of ''speculate'', ''collaborate'', and ''learn'' cycles. This dynamic cycle provides for continuous learning and adaptation to the emergent state of the project. The characteristics of an ASD life cycle are that it is mission focused, feature based, iterative, timeboxed, risk driven, and change tolerant. As with RAD, ASD is also an antecedent to agile software development. The word ''speculate'' refers to the paradox of planning – it is more likely to assume that all stakeholders are comparably wrong for certain aspects of the project’s mission, while trying to define it. During speculation, the proj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANZ Bank
The Australia and New Zealand Banking Group Limited, commonly known as ANZ Bank, is a multinational banking and financial services company headquartered in Melbourne, Victoria, Australia. It is Australia's second-largest bank by assets and fourth-largest bank by market capitalisation. Its current corporate entity was established on 1 October 1970, when the Australia and New Zealand Bank (ANZ) merged with the English, Scottish & Australian Bank (ES&A). It was the largest bank merger in Australian history at the time. The Australia and New Zealand Bank had in turn been founded in 1951 as a merger of the Bank of Australasia and the Union Bank of Australia, which were established in 1835 and 1837 respectively. ANZ is one of the Big Four Australian banks, along with the Commonwealth Bank, National Australia Bank and Westpac. Australian operations make up the largest part of ANZ's business, with commercial and retail banking dominating. ANZ is also the largest bank in New Zeala ...

Output (computing)
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include Computer monitor, monitors, Printer (computing), printers and sound cards. In an industrial setting, output devices also include "printers" for paper tape and punched cards, especially where the tape or cards are subsequently used to control industrial equipment, such as an industrial loom with electrical robotics which is not fully computerized Visual A ''display device'' is the most common form of output device which presents output visually on computer screen. The output appears temporarily on the screen and can easily be altered or erased. With all-in-one PCs, notebook computers, hand held PCs and other devices; the term display screen is used for the display device. The display devices a ...

In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device. Some computer devices can also be categorized as input devices, because devices are used to send instructions to the computer, some common examples of computer input devices are: * Mouse |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation prototypical. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms ...

Model
A model is an informative representation of an object, person, or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin , . Models can be divided into physical models (e.g. a ship model or a fashion model) and abstract models (e.g. a set of mathematical equations describing the workings of the atmosphere for the purpose of weather forecasting). Abstract or conceptual models are central to philosophy of science. In scholarly research and applied science, a model should not be confused with a theory: while a model seeks only to represent reality with the purpose of better understanding or predicting the world, a theory is more ambitious in that it claims to be an explanation of reality. Types of model ''Model'' in specific contexts As a noun, ''model'' has specific meanings in certain fields, derived from its original meaning of "structural design or layout": * Model (art), ...

Systems Analyst
A systems analyst, also known as business technology analyst, is an information technology (IT) professional who specializes in analyzing, designing and implementing information systems. Systems analysts assess the suitability of information systems in terms of their intended outcomes and liaise with end users, software vendors and programmers in order to achieve these outcomes.Shelly, Gary B., Cashman, Thomas J., & Vermaat, Misty E. ''Discovering Computers 2008, Complete.'' Boston: Thomson Course Technology. ISBN 1 -4239-1205-5 A systems analyst is a person who uses analysis and design techniques to solve business problems using information technology. Systems analysts may serve as change agents who identify the organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.

Scope (project Management)
In project management Project management is the process of supervising the work of a Project team, team to achieve all project goals within the given constraints. This information is usually described in project initiation documentation, project documentation, crea ..., scope is the defined features and functions of a product, or the scope of work needed to finish a project. Scope involves getting information required to start a project, including the features the product needs to meet its stakeholders' requirements. Project scope is oriented towards the work required and methods needed, while product scope is more oriented toward functional requirements. If requirements are not completely defined and described and if there is no effective change control in a project, scope or requirement creep may ensue. Scope management is the process of defining, and managing the scope of a project to ensure that it stays on track, within budget, and meets the expectations of stakeholde ...

Business Requirements
Business requirements (BR), also known as stakeholder requirements specifications (StRS), describe the characteristics of a proposed system from the viewpoint of the system's end user like a CONOPS. Products, systems, software, and processes are ways of ''how'' to deliver, satisfy, or meet business requirements. Consequently, business requirements are often discussed in the context of developing or procuring software or other systems. Three main reasons for such discussions: #A common practice is to refer to objectives, or expected benefits, as 'business requirements.' #People commonly use the term 'requirements' to describe the features of the product, system, software expected to be created. #A widely held model claims that these two types of requirements differ only in their level of detail or abstraction — wherein 'business requirements' are high-level, frequently vague, and decompose into the detailed product, system, or software requirements.

Systems Development Life Cycle
In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation. Overview A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems. Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. Computer systems are complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
