INVEST (mnemonic)
The INVEST mnemonic for Agile software development projects was created by Bill Wake as a reminder of the characteristics of a good quality Product Backlog Item (commonly written in user story format, but not required to be) or PBI for short. Such PBIs may be used in a Scrum backlog, Kanban board or XP project. Independent One of the characteristics of Agile Methodologies such as Scrum, Kanban or XP is the ability to move PBIs around, taking into account, amongst other criteria, their business value. When PBIs are tightly dependent, it might be possible to combine them into a single PBI. Negotiable According to Agile methodology, while the PBI lies in the product backlog it can be rewritten or even discarded, depending on business, market, technical or any other type of requirement by team members. Most notably though, Negotiability relates to the degree to which the Developer has freedom to negotiate the detail of the solution with the Business once in development. A draft st ...

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] |
Jeff Sutherland
Jeff Sutherland (born June 20, 1941) is one of the creators of Scrum, a framework for product management. Together with Ken Schwaber, he presented Scrum at OOPSLA'95. Sutherland contributed to the creation of the Agile Manifesto in 2001. Along with Ken Schwaber, he wrote and maintains ''The Scrum Guide'', which contains the official definition of the framework. Early career Sutherland is a graduate of the United States Military Academy. In 1967 he deployed with the United States Air Force to Udorn Royal Thai Air Force Base to fly reconnaissance flights in a RF-4C Phantom. After returning from the Vietnam war, Sutherland earned a master's degree in statistics from Stanford University. He then became a professor of mathematics at the United States Air Force Academy. Sutherland earned a doctorate in biometrics at the University of Colorado School of Medicine.

Quality Management
Total quality management, Total Quality management (TQM), ensures that an organization, product, or service consistently performs as intended, as opposed to Quality Management, which focuses on work process and procedure standards. It has four main components: quality planning, quality assurance, quality control, and quality improvement. Customers recognize that quality is an important attribute when choosing and purchasing products and services. Suppliers can recognize that quality is an important differentiator of their offerings, and endeavor to compete on the quality of their products and the service they offer. Thus, quality management is focused both on product and service quality. Advancement In earlier periods, arts and crafts were led by Master craftsman, master craftspeople or artists who supervised studios, trained apprentices, and oversaw the product development process. With the advent of the Industrial Revolution, steam engines, and mass production, the role of crafts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Requirements Engineering
Requirements engineering (RE) is the process of defining, documenting, and maintaining requirements in the engineering design process. It is a common role in systems engineering and software engineering. The first use of the term ''requirements engineering'' was probably in 1964 in the conference paper "Maintenance, Maintainability, and System Requirements Engineering", but it did not come into general use until the late 1990s with the publication of an IEEE Computer Society tutorial in March 1997 and the establishment of a conference series on requirements engineering that has evolved into the International Requirements Engineering Conference. In the waterfall model, requirements engineering is presented as the first phase of the development process. Later development methods, including the Rational Unified Process (RUP) for software, assume that requirements engineering continues through a system's lifetime. Requirements management, which is a sub-function of Systems En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Test-driven Development
Test-driven development (TDD) is a way of writing source code, code that involves writing an test automation, automated unit testing, unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case. Alternative approaches to writing automated tests is to write all of the production code before starting on the test code or to write all of the test code before starting on the production code. With TsDD, both are written together, therefore shortening debugging time necessities. TDD is related to the test-first programming concepts of extreme programming, begun in 1999, but more recently has created more general interest in its own right.Newkirk, JW and Vorontsov, AA. ''Test-Driven Development in Microsoft .NET'', Microsoft Press, 2004. Programmers also apply the concept to improving and software bug, debugging legacy code developed with older techniques.Feat ...

Lean Software Development
Lean software development is a translation of lean manufacturing principles and practices to the software development domain. Adapted from the Toyota Production System, it is emerging with the support of a pro-lean subculture within the agile community. Lean offers a solid conceptual framework, values and principles, as well as good practices, derived from experience, that support agile organizations. Origin The expression "lean software development" originated in a book by the same name, written by Mary Poppendieck and Tom Poppendieck in 2003. The book restates traditional lean principles, as well as a set of 22 ''tools'' and compares the tools to corresponding agile practices. The Poppendiecks' involvement in the agile software development community, including talks at several Agile conferences has resulted in such concepts being more widely accepted within the agile community. Lean principles Lean development can be summarized by seven principles, very close in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanban
Kanban ( meaning signboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. The system takes its name from the cards that track production within a factory. Kanban is also known as the ''Toyota nameplate system'' in the automotive industry. A goal of the kanban system is to limit the buildup of excess inventory at any point in production. Limits on the number of items waiting at supply points are established and then reduced as inefficiencies are identified and removed. Whenever a limit is exceeded, this points to an inefficiency that should be addressed. In kanban, problem areas are highlighted by measuring lead time and cycle time of the full process and process steps. One of the main benefits of kanban is to establish an upper limit to work in process (commonly referred as "WIP") inventory to avoid overcapacity. ...

Testable
Testability is a primary aspect of science and the scientific method. There are two components to testability: #Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. #The practical feasibility of observing a reproducible series of such counterexamples if they do exist. In short, a hypothesis is testable if there is a possibility of deciding whether it is true or false based on experimentation by anyone. This allows anyone to decide whether a theory can be supported or refuted by data. However, the interpretation of experimental data may be also inconclusive or uncertain. Karl Popper introduced the concept that scientific knowledge had the property of falsifiability as published in '' The Logic of Scientific Discovery''.Karl Popper "The Logic of Scientific Discovery", 1934 (as ''Logik der Forschung'', English translation 1959), ISBN 0415278449 and 2002 ISBN 9780415278447, 0415278449 See also * Confirmability * Controlla ...

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 ...
