Ripple effect analysis of software maintenance

Abstract

Maintenance of l a r g e -s c a l e software systems i s Large-scale s o f ta complex and expensive process. ware systems o f t e n possess both a s e t of functiona l and performance requirements. Thus, i t i s imp o r t a n t f o r maintenance personnel t o consider t h e r a m i f i c a t i o n s of a proposed program modification from both a f u n c t i o n a l and a performance perspect i v e .

Software architecture evolution through evolvability analysis

“…Several process models have been proposed and gained widespread acceptance since the late seventies as the term software evolution was deliberately used and recognized by the research community. Some examples are the waterfall model [155], change mini-cycle process model [182], evolutionary development model [78,79], spiral model [24], Agile software development [57,121], and staged model [21]. Our research is in line with the idea in staged model [21], which explicitly takes into account the issue of software aging [137], and represents the software lifecycle as a sequence of the following stages:…”

“…One such figure has been proposed which reflects the amount of work involved in performing maintenance and thus provides a standard on which comparisons of modifications can be made [2]. However, further research is required for estimating such a figure.…”

Software Change and Evolution

“…For example if verification discovers problems, the minicycle may reenter one of the earlier phases. The actual phases of the minicycle are presented in the literature in several different forms [24], but they all capture the same basic idea. This paper avoids the complexities o f the actual minicycle and presents this simplified version as a context for the techniques described in the following sections.…”
