Estimating in Agile Scrum Software Development
written by gunther gerlach-2009
There are many approaches for the estimation of a project. Some people will tell you to use the estimation based on story points from Fibonacci numbering system, however this approach only work when features are similar enough to keep a project velocity chart (average project velocity per sprint) in your project but, we all know that this is impossible, some features will need less than a hour of development and other sometimes two days. I am not saying that this methodology is not good, I am just saying that is perfect to get your project velocity chart from the project but if you really want an estimate to get the cost and scope from your project you need the estimate in a period of time, usually days of work.
