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. Agile software development methods recommend the use of Planning Poker for estimating the size of user stories and developing release and iteration plans. 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'', who ...

Gamification
Gamification is the process of enhancing systems, services, organisations and activities through the integration of game design elements and principles in non-game contexts. The goal is to increase user engagement, motivation, competition and participation through the use of game mechanics such as points, badges, leaderboards and rewards. It is a component of system design, and it commonly employs game design elements to improve user engagement, organizational productivity, flow, learning, crowdsourcing, knowledge retention, employee recruitment and evaluation, usability, usefulness of systems, physical exercise, tailored interactions and icebreaker activities in dating apps, 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. Gamification can be achi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibonacci Sequence
In mathematics, the Fibonacci sequence is a Integer sequence, sequence in which each element is the sum of the two elements that precede it. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 and some (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the sequence begins : 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, also known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book . Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the ''Fibonacci Quarterly''. Appli ...

Soapbox
A soapbox is a raised platform on which one stands to make an impromptu speech, often about a 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. 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. In the context of the World Wide Web, blogs can be used as soapboxes 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 shipment of wholesale merchandise to retail establishments. Discarded containers of every size, well-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Story Point
A burndown chart or burn-down chart is a graphical representation of work left to do versus time. The outstanding work (or backlog) is often on the vertical axis, with time along the horizontal. A burndown chart is a run chart of remaining work. It is useful for predicting when all of the work will be completed. It is often used in agile software development methodologies such as Scrum. However, burndown charts can be applied to any project containing measurable progress over time. Remaining work can be represented in terms of either time or story points (a sort of arbitrary unit). Burn charts can be used to present the project's team velocity Velocity is a measurement of speed in a certain direction of motion.

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. Ap ...

Web Applications
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoot ...

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." Regarding 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 users to make parallel edits to a file, while preserving every saved edit by users 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 collaborative acti ... [...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."

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Story
In software development and product management, a user story is an informal, natural language description of features of a software system. They are written from the perspective of an end user or user of a system, and may be recorded on index cards, Post-it notes, or digitally in specific management software. Depending on the product, user stories may be written by different stakeholders like client, user, manager, or development team. User stories are a type of boundary object. They facilitate sensemaking and communication; and may help software teams document their understanding of the system and its context. History * 1997: Kent Beck introduces user stories at the Chrysler C3 project in Detroit. * 1998: Alistair Cockburn visited the C3 project and coined the phrase "A user story is a promise for a conversation." * 1999: Kent Beck published the first edition of the book ''Extreme Programming Explained'', introducing Extreme Programming (XP), and the usage of user stori ...

Timeboxing
In agile principles, timeboxing allocates a maximum unit of time to an activity, called a timebox, within which a planned activity takes place. It is used by agile principles-based project management approaches and for personal time management. In project management Timeboxing is used as a project planning technique. The schedule is divided into a number of separate time periods (timeboxes), with each part having its own deliverables, deadline and budget. Sometimes referred to as ''schedule as independent variable'' (SAIV). "Timeboxing works best in multistage projects or tasks that take little time and you can fit them in the same time slot. It is also worth implementing in case of duties that have foreseeable time-frames of completion." As an alternative to fixing scope In project management, there are generally considered to be three constraints: time (sometimes schedule), cost (sometimes budget), and scope. (Quality is often added as a fourth constraint---represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
