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 ]
Use case points (UCP or UCPs) is a software estimation technique used to forecast the software size for software development projects. UCP is used when the Unified Modeling Language (UML) and Rational Unified Process (RUP) methodologies are being used for the software design and development.
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.
Other software sizing methods include Use Case-based software sizing, which relies on counting the number and characteristics of use cases found in a piece of software, and COSMIC functional size measurement, which addresses sizing software that has a very limited amount of stored data such as 'process control' and 'real time' systems.
Function point analysis measures the size of the software deliverable from a user's perspective. Function point sizing is done based on user requirements and provides an accurate representation of both size for the developer/estimator and value (functionality to be delivered) and reflects the business functionality being delivered to the customer.
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.
The method breaks down the Functional User Requirements of the software into combinations of the four data movements types: Entry (E) Exit (X) Read (R) Write (W) The function point count provides measurement of software size, which is the sum of the data movements for a given functional requirement. It may be used to estimate (and benchmark ...
