There are a lot of aspect-oriented approaches presenting solutions for the diff erent phases of the Software Development Life Cycle (SDLC). However, there is no approach with a coherent process and employing standard representations and tools along the whole SDLC. We have elaborated an alternative called Aspect-Oriented Process for a Smooth Transition (AOP4ST), that allows the smooth incorporation of the aspect-oriented paradigm in the current industrial projects and off ers a complete homogenous proposal for the phases of the SDLC. In this paper, we present how to fi nd concerns at the fi rst stages of AOP4ST, when we move from the business model to the software requirements model, performing the requirement development activity of requirement engineering.
