This paper presents an improved approach to the estimation of software testing efforts for web based projects in maintenance phase. The approach emerged by the study of pros & cons in different existing estimation models and also their difficulty to apply for projects in maintenance phase. It mainly focuses on the reduction of computational cost in Estimation. It also identifies the way to improve all possible rework & risks involved in Maintenance phase. This approach enables effort estimates for different phases of testing. Though the target audiences are those who work on web-based applications in Maintenance/enhancement phases, many of the advantages discussed here are common for projects in development phase too. Further work could provide how we can standardize the linking parameters & the effort needed for test phases.

Annamariale is a B.Tech in Electronics & Instrumentation Engg.
