Length of an Iteration
Thanks.
Thanks.
It depends on many factors, so a good guess for one situation may not be applicable to another. Three people working closely together on a simple application may determine that a week is adequate, whereas a larger team working on a more complex application may determined that a month or more is needed. Even then, the length of an iteration can vary within the context of a single project.
Essentially, you want to have something to show for your efforts at the end of an iteration that repesents a gain in functionality, performance, or some other aspect. How long it takes to achieve that should guide your determination.
