Agile Modeling with Mind Map and UML

Abstract
Requirement Gathering or Gathering User Stories
(in Agile context) is always a challenging phase in
software development. There are no standard
processes or notations defined, In addition,
communication and facilitation skills are the primary
factor that makes the activity effective. In this paper, I
propose a new method for exploring Ŷser Wish¡¦
using Mind Maps and then model it using UML.
