Abstract
In this paper, the performance impact analysis of egovernment systems with key performance parameters is being considered. Meaningful impact analysis in sustained government systems is required for considering non-functional requirements and functional requirements. Performance requirements are a critical component of non-functional areas. For example, if a new system change is set to the system, the impact in terms of the response time must be implemented in each sub-system. In this paper, an XML-based framework can be used to analyze performance impacts on sub-systems and can provide a scheme to enhance impact analysis by performance monitoring using application response measurement. Through a health system example as a case study, a performance requirement model to describe extended trees and adapting analysis result of performance monitoring using application response measurement and XML tree representation are addressed. This paper also proposes a scheme for prioritized processing and an algorithm for effectively enhancing impact analysis in a timely fashion.
1. Introduction
In a sustained system, impact analysis is required to make decisions prior to making system changes associated with new requirements [1]. System engineers are faced with the problem of analyzing nonfunctional impacts as well as functional impacts. There is a growing recognition of the role of the system engineer in determining the quality of a system. This analysis is driven by non-functional requirements such as performance, security, reliability, modifiability, reusability, and economic constraints. Among these requirements, the performance requirement is a critical component in the non-functional area. Most
performance failures occur due to a lack of consideration of performance issues in the
