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] |
Agile Software Development
In software development, agile (sometimes written Agile) practices include requirements discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/ end user(s), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved. Popularized in the 2001 ''Manifesto for Agile Software Development'', these values and principles were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban. While there is much anecdotal evidence that adopting agile practices and values improves the effectiveness of software professionals, teams and organizations, the empirical evidence is mixed and hard to find. History Iterative and incremental software development methods can be traced back as early as 1957, Gerald M. Weinberg, as quoted in " ...

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 project management software. Depending on the project, 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 stories i ...
