It is a simple, but power technique to generate a reasonably reliable estimate about what the team is capable of doing, and the rate at which it can deliver completed user stories at the end of the sprint. It is important to know that the stories developed should be totally "complete" and "shippable" to be considered for the estimation. User stories accepted as "done" are included for the velocity calculation in scrum.Why it is necessary to estimate velocityScrum includes a lot of planning, and setting up of goals when it is to be implemented. The product owner prepares a product backlog, which contains the list of user stories or the requirements needed to manufacture the product. Pandora Clearance Charms Once the list is prepared, the person is required to give an estimation to the investors and stakeholders Pandora Clearance Online as to how long the product will take to develop, and when it can be availed for selling purposes. This is when an issue comes in how can a proper estimate be given regarding the product development? In case of traditional development methodologies such as Waterfall, the estimate is generally given by calculating the working hours based upon the productivity delivered by individual team members. In case of scrum this is not possible, since the focus is upon the team as a whole. Individual effort does not count in scrum. It is what the team delivers as a whole unit which is more important. Moreover, team members possess varying levels of expertise. An experienced developer might complete a task in two hours, while a novice or an amateur might complete the same task in eight hours. It further adds on to the complexity of creating a trustworthy estimate.What are story points in scrum?To overcome this problem, points known as "story points" are allotted to each user story based upon its level of difficulty. Simple and easy stories carry fewer points while difficult ones carry a higher weightage. A story point is an arbitrary number value assigned to a story to indicate the complexity associated with the functionality linked with the development. In simple words the story point conveys how complex and difficult the particular requirement is. The story point can be an integer, however it can also be fractional depending upon the manner in which the complexity is determined for a particular requirement. For example, an experienced programmer might find a particular task easy, and assign five points to a story. A novice developer might find the task difficult and assign ten points to it. So the user story can be associated with two values depending upon who develops the story five and ten. This is in contradiction, since the story point should be a unique number. It cannot assume two values.Story pointsNovice programmer 5Mean value [(10 + 5) / 2] (two programmers) = 7.5The story point value for the above example would be 7.5.How are story points and velocity related?Once the product backlog is created, the product owner is liable to provide an estimation regarding the project completion. The person starts assigning story points to the user stories contained within the backlog. He or she may also request help or advice from the scrum master as and when Pandora Clearance Outlet required while assigning the points. Once all the stories are linked up with Pandora Clearance appropriate story points, all the points are added up to form a grand total. This total provides an idea how big or large the entire project is. For example, a project may include user stories which may total three hundred points. It becomes possible to create an estimate once a grand total is available.Mrugesh Panchal is a director in Bharti Consulting Services SARL, an ISO 9001 2008 certified IT Service Provider Company having its headquarters in Clichy, France and its operations center in Vadodara, Gujarat India.
