Estimation of Defects Based on
Defect Decay Model: ED3M
Abstract:

An accurate prediction of the number of defects in a software product during system testing contributes not only to the management of the system testing process but also to the estimation of the product s required maintenance. Here, a new approach, called Estimation of Defects based on Defect Decay Model (ED3M) is presented that computes an estimate the defects in an ongoing testing process. ED3M is based on estimation theory. Unlike many existing approaches, the techniqu ....etc

ABSTRACT
In today s business where speed is of essence, an iterative development approach that
allows the functionality to be delivered in parts has become a necessity and an effective
way to manage risks. In an iterative process, the development of a software system is done
in increments, each increment forming of an iteration and resulting in a working system. A
common iterative approach is to decide what should be developed in an iteration and then
plan the iteration accordingly. A somewhat different iterative is approach is to ....etc
