Spike (software Development)
A spike is a product development method originating from extreme programming that uses the simplest possible program to explore potential solutions. It is used to determine how much work will be required to solve or work around a software issue. Typically, a "spike test" involves gathering additional information or testing for easily reproduced edge cases. The term is used in agile software development approaches like Scrum or Extreme Programming. Uses A spike in a sprint can be used in a number of ways: * As a way to familiarize the team with new hardware or software * To analyze a problem thoroughly and assist in properly dividing work among separate team members. * Spike tests can also be used to mitigate future risk, and may uncover additional issues that have escaped notice. A distinction can be made between technical spikes and functional spikes. The technical spike is used more often for evaluating the impact new technology has on the current implementation.

Extreme Programming
Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development,"Human Centred Technology Workshop 2006 ", 2006, PDFHuman Centred Technology Workshop 2006 /ref> it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted. Other elements of extreme programming include programming in pairs or doing extensive code review, unit testing of all code, not programming features until they are actually needed, a flat management structure, code simplicity and clarity, expecting changes in the customer's requirements as time passes and the problem is better understood, and frequent communication with the customer and among programmers.

Edge Case
An edge case is a problem or situation that occurs only at an extreme (maximum or minimum) operating parameter. For example, a stereo speaker might noticeably distort audio when played at maximum volume, even in the absence of any other extreme setting or condition. An edge case can be expected or unexpected. In engineering, the process of planning for and gracefully addressing edge cases can be a significant task, and yet this task may be overlooked or underestimated. Some common causes of edge cases are: * Unpredictable user behavior * Evolution of use cases (e.g. user behavior may change over time) * Limited test coverage * Product complexity (for instance, in distributed systems or microservice architectures) * Resource limitations (e.g. limited processing power, computer memory, or computer storage) * Other external causes Some basic examples of edge cases include: * A long username in an app overflows and displays incorrectly * A booking system does not handle reservati ...

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 ...

Scrum (software Development)
Scrum is an Agile management, agile team collaboration framework commonly used in software development and other industries. Scrum prescribes for teams to break work into goals to be completed within Timeboxing, time-boxed iterations, called ''sprints''. Each sprint is no longer than one month and commonly lasts two weeks. The scrum team assesses progress in time-boxed, stand-up meeting, stand-up meetings of up to 15 minutes, called ''daily scrums''. At the end of the sprint, the team holds two further meetings: one sprint review to demonstrate the work for Stakeholder (corporate), stakeholders and solicit feedback, and one internal Retrospective#Software development, sprint retrospective. A person in charge of a scrum team is typically called a scrum master. Scrum's approach to product development involves bringing decision-making authority to an operational level. Unlike a sequential approach to product development, scrum is an Iterative design, iterative and Iterative an ... [...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 ...
