The requirement to improve software productivity has promoted the research on software metrics technology. Object Oriented paradigm is the technology being used to build fault free and stupendous softwares; and to make them fault free object oriented metrics are being used. These metrics are used to identify high risk components early in the design phase and hence help us to reduce the rework a...

This paper is devoted to the study of production systems with rework loops. Such systems are often encountered in manufacturing plants and accurate performance analysis is needed for design and continuous improvement. However, no analytical methods to evaluate its production rate are available in the current literature. In this paper, we present an aggregation procedure using overlapping decomp...

s information technology provides industry with the means to identify new product and service opportunities, the increasing demand for these products and services places new demands on information technology. This cycle has created unprecedented requirements for integrated enterprise systems and applications, which are capable of modeling rapid changes in business policies, workflow and informa...

Fagan inspections are a structured review of development documents that consists of individual preparation, a meeting and rework by the author of the document. The meeting is used to log the defects found in preparation and to search for more defects. The effectiveness and eficiency of the meeting is typically low as compared to that of the preparation. This paper describes the use of an EMS to...

Reworking in developing software exists widely in IT project management. But the current estimating methods on project duration cannot deal well with this problem. In this paper, some key concepts, such as adjusted activity, adjusted GERT network, expected project duration, expected critical path, are firstly defined. Then authors study estimating method on project duration for different rework...
