Planning Poker
Planning poker, also called Scrum poker, is a consensus-based, gamified technique for estimating, mostly used for timeboxing in '' Agile principles''. In planning poker, members of the group make estimates by playing numbered cards face-down to the table, instead of speaking them aloud. The cards are revealed, and the estimates are then discussed. By hiding the figures in this way, the group can avoid the cognitive bias of anchoring, where the first number spoken aloud sets a precedent for subsequent estimates. Planning poker is a variation of the Wideband delphi method. It is most commonly used in agile software development, in particular in Scrum and Extreme Programming. The method was first defined and named by James Grenning in 2002 and later popularized by Mike Cohn in the book ''Agile Estimating and Planning'', whose company trade marked the term and a digital online tool. Process Rationale The reason to use planning poker is to avoid the influence of the other par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamification
Gamification is the strategic attempt to enhance systems, services, organizations, and activities by creating similar experiences to those experienced when playing games in order to motivate and engage users. This is generally accomplished through the application of game-design elements and game principles (dynamics and mechanics) in non-game contexts. Gamification is part of persuasive system design, and it commonly employs game design elements to improve user engagement, organizational productivity, flow, learning, crowdsourcing, knowledge retention, employee recruitment and evaluation, ease of use, usefulness of systems, physical exercise, traffic violations, voter apathy, public attitudes about alternative energy, and more. A collection of research on gamification shows that a majority of studies on gamification find it has positive effects on individuals. However, individual and contextual differences exist. Techniques Gamification techniques are intended to leverag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development Effort Estimation
In software development, effort estimation is the process of predicting the most realistic amount of effort (expressed in terms of person-hours or money) required to develop or maintain software based on incomplete, uncertain and noisy input. Effort estimates may be used as input to project plans, iteration plans, budgets, investment analyses, pricing processes and bidding rounds. State-of-practice Published surveys on estimation practice suggest that expert estimation is the dominant strategy when estimating software development effort. Typically, effort estimates are over-optimistic and there is a strong over-confidence in their accuracy. The mean effort overrun seems to be about 30% and not decreasing over time. For a review of effort estimation error surveys, see. However, the measurement of estimation error is problematic, see Assessing the accuracy of estimates. The strong overconfidence in the accuracy of the effort estimates is illustrated by the finding that, on average, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibonacci Scale (agile)
In Agile software development, the Fibonacci scale consists of a sequence of numbers used for estimating the relative size of user stories in points. Agile Scrum is based on the concept of working iteratively in short sprints, typically two weeks long, where the requirements and development are continuously being improved. The Fibonacci sequence consists of numbers that are the summation of the two preceding numbers, starting with , 1 Agile uses the Fibonacci sequence to achieve better results by reducing complexity, effort, and doubt when determining the development time required for a task, which can range from a few minutes to several weeks. Procedure It is easier to determine the relative complexity of a task rather than figuring out how much time it requires. Due to this, when working with agile, a revised Fibonacci scale is used in terms of points to estimate the work, as opposed to the traditional measurement of time. In one method commonly used to calculate the size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soapbox
A soapbox is a raised platform on which one stands to make an wiktionary:impromptu, impromptu speech, often about a Politics, political subject. The term originates from the days when speakers would elevate themselves by standing on a wooden crate originally used for shipment of soap, or other dry goods, from a manufacturer to a retail store. The term is also used metaphorically to describe a person engaging in often flamboyant, impromptu, or unofficial public speaking, as in the phrase, "Get off your soapbox." Hyde Park, London, Hyde Park in London is known for its Sunday soapbox orators, who have assembled at its Speakers' Corner since 1872 to discuss religion, politics, and other topics. Blogs can be used as soapboxes within the context of the World Wide Web, and are often used for promotional purposes. History Origins of the term Throughout the 19th Century and into the 20th, prior to the invention of corrugated fiberboard, manufacturers used wooden crates for the shipme ...

Anchoring
An anchor is a device, normally made of metal , used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ''ancora'', which itself comes from the Greek ἄγκυρα (ankȳra). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large masses (common ...

Mobile Applications
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for " application", has since become very popular; in 2010, it was listed as "Word of the Year" by the American Dialect Society. Apps are ...

Web Applications
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for all but the large ...

Collaborative Software
Collaborative software or groupware is application software designed to help people working on a common task to attain their goals. One of the earliest definitions of groupware is "intentional group processes plus software to support them". As regards available interaction, collaborative software may be divided into: real-time collaborative editing platforms that allow multiple users to engage in live, simultaneous and reversible editing of a single file (usually a document), and version control (also known as revision control and source control) platforms, which allow separate users to make parallel edits to a file, while preserving every saved edit by every user as multiple files (that are variants of the original file). Collaborative software is a broad concept that overlaps considerably with computer-supported cooperative work (CSCW). According to Carstensen and Schmidt (1999) groupware is part of CSCW. The authors claim that CSCW, and thereby groupware, addresses "how colla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Team
A virtual team (also known as a geographically dispersed team, distributed team, or remote team) usually refers to a group of individuals who work together from different geographic locations and rely on communication technology such as email, instant messaging, and video or voice conferencing services in order to collaborate.Gibson, C. B., and S. G. Cohen (2003). Virtual Teams That Work: Creating Conditions for Virtual Collaboration Effectiveness. San Francisco: Jossey-Bass.Martins, L. L., L. L. Gilson, and M. T. Maynard 2004 “Virtual teams: What do we know and where do we go from here?” Journal of Management, 30: 805–835. The term can also refer to groups or teams that work together asynchronously or across organizational levels. Powell, Piccoli and Ives (2004) define virtual teams as "groups of geographically, organizationally and/or time dispersed workers brought together by information and telecommunication technologies to accomplish one or more organizational tasks."

Fibonacci Sequence
In mathematics, the Fibonacci numbers, commonly denoted , form a integer sequence, sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the first few values in the sequence are: :0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144. The Fibonacci numbers were first described in Indian mathematics, as early as 200 BC in work by Pingala on enumerating possible patterns of Sanskrit poetry formed from syllables of two lengths. They are named after the Italian mathematician Leonardo of Pisa, later known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book ''Liber Abaci''. Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the ''Fibonacci Quarterly''. Applications of Fibonacci ...
