Abstract

Enhanced Measurement for Early Risk Assessment of Latent Defects(EMERALD) is a decision support system for assessing reliability risk.It is used by software developers and managers to improvetelecommunications software service quality as perceived by the customerand the end user. Risk models are based on static characteristics ofsource code. This paper shows how a system such as EMERALD can enhancesoftware development, testing, and maintenance by integration of: asoftware quality improvement strategy; measurements and models; anddelivery of results to the desktop of developers in a timely manner.This paper also summarizes empirical experiments with EMERALD's modelsusing data from large industrial telecommunications software systems.EMERALD has been applied to a very large system with over 12 millionlines of source code within procedures. Experience and lessons learnedare also discussed
