Aspect composition in problem frames

Abstract

Problem frames (PFs) is a problem domain-oriented approach, focusing on understanding the problem, instead of its design solutions. PFs support the identification of problem domains, provide mechanisms to analyse and structure problems and promote reusability by dealing with different types of known problems. The motivation for this work is the early evidence that Jackson's problem frames include many scattered and tangled model elements that correspond to crosscutting requirements. This chapter offers specific guidelines to define and compose crosscutting concerns in PFs. The proposed approach uses a specification template for aspectual requirements and abstract problem diagrams. The advantage lays on providing support for modularization of requirements and domain knowledge.
