Continuous monitoring of changes to utility services and products in a distributed information system is an interesting issue in software engineering. These changes affect the semantics and structural complexity of the system, as a change to one part will in most cases, result in changes to other parts. Therefore, in design and redesign for customization, predicting this change presents a significant challenge. Changes are intended to fix faults, improve or update products and services. Lack of validated, widely accepted, and adopted tools for planning, estimating, and performing maintenance contributes to the problem. One effective way of assessing changeability effect is to assess the impact of changes through a well validated model and framework.
