Agile software development methods recommend the use of Planning Poker for estimating the size of user stories and developing release and iteration plans. [ 1 ] The method was first defined and named by James Grenning in 2002 [ 2 ] and later popularized by Mike Cohn in the book Agile Estimating and Planning , [ 3 ] whose company trade marked ...
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. [ 1 ]
Sort by Value: Business sorts the user stories by Business Value. Sort by Risk: Development sorts the stories by risk. Set Velocity: Development determines at what speed they can perform. Choose scope: The user stories that will be finished in the next release will be picked. Based on the user stories the release date is determined.
Function points were defined in 1979 in Measuring Application Development Productivity by Allan J. Albrecht at IBM. [4] The functional user requirements of the software are identified and each one is categorized into one of five types: outputs, inquiries, inputs, internal files, and external interfaces.
Software sizing or software size estimation is an activity in software engineering that is used to determine or estimate the size of a software application or component in order to be able to implement other software project management activities (such as estimating or tracking).
SEER for Software (SEER-SEM) is composed of a group of models working together to provide estimates of effort, duration, staffing, and defects. These models can be briefly described by the questions they answer: Sizing. How large is the software project being estimated (Lines of Code, Function Points, Use Cases, etc.) Technology.
The INVEST mnemonic for Agile software development projects was created by Bill Wake [1] 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.
