Planning poker, also called Scrum poker, is a consensus-based, gamified technique for estimating, mostly used for timeboxing in Agile principles. In planning poker, members of the group make estimates by playing numbered cards face-down to the table, instead of speaking them aloud. The cards are revealed, and the estimates are then discussed.
A Fibonacci prime is a Fibonacci number that is prime. The first few are: [46] 2, 3, 5, 13, 89, 233, 1597, 28657, 514229, ... Fibonacci primes with thousands of digits have been found, but it is not known whether there are infinitely many. [47] F kn is divisible by F n, so, apart from F 4 = 3, any Fibonacci prime must have a prime index.
It is useful for predicting when all of the work will be completed. It is often used in agile software development methodologies such as Scrum. However, burndown charts can be applied to any project containing measurable progress over time. Remaining work can be represented in terms of either time or story points (a sort of arbitrary unit). [2]
One way of estimating is by giving each task a number of story points selected from the Fibonacci sequence: 1, 2, 3, 5, 8, 13, with the simplest tasks given a score of 1 and more complex tasks given higher scores. When user stories are about to be implemented, the developers should have the possibility to talk to the customer about it.
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.
A spike is a product development method originating from extreme programming that uses the simplest possible program to explore potential solutions. [1] It is used to determine how much work will be required to solve or work around a software issue.
The expansion produced by this method for a number is called the greedy Egyptian expansion, Sylvester expansion, or Fibonacci–Sylvester expansion of . However, the term Fibonacci expansion usually refers, not to this method, but to representation of integers as sums of Fibonacci numbers .
F, also called the Fibonacci factorial, where n is a nonnegative integer, is defined as the product of the first n positive Fibonacci numbers, i.e. !:= =,, where F i is the i th Fibonacci number, and 0! F gives the empty product (defined as the multiplicative identity, i.e. 1).
