Regression testing has been used to support software testing activities and assure the acquirement of appropriate quality through several versions of a software program. Regression testing, however, is too expensive because it requires many test case executions, and the number of test cases increases sharply as the software evolves. In this paper, we propose the Historical Value-Based Approach, which is based on the use of historical information, to estimate the current cost and fault severity f

Many web-based software systems have been developed in the form of composite services. It is important to accurately predict the Quality of Service (QoS) value of atomic web services because the performance of such composite services depends greatly on the performance of the atomic web service adopted. In recent years, collaborative filtering based methods for predicting the web service QoS values have been proposed. However, they are mainly faced with a cold start problem that is difficult to m

UML activity diagram is a notation suitable for modeling a concurrent system in which multiple objects interact with each other. This paper proposes a method to generate test cases from UML activity diagrams that minimizes the number of test cases generated while deriving all practically useful test cases. Our method first builds an I/O explicit activity diagram from an ordinary UML activity diagram and then transforms it to a directed graph, from which test cases for the initial activity diagra

CASE (computer aided software engineering) tools are believed to have played a critical role in improving software productivity and quality by assisting tasks in software development processes since the 1970s. Several parametric software cost models adopt "use of software tools" as one of the environmental factors that affects software development productivity. Several software cost models assess the productivity impacts of CASE tools based only on breadth of tool coverage without considering ot

In this paper, we present a software cost estimation model for agile development which can help estimate concrete development costs for the desired features of a product and track the project progress dynamically. In general, existing cost estimation methods for agile developments used a story point. Because it is relative value, the estimation results tend to be easily fluctuated by the small variation of the baseline story point. For tracking project’s progress, the velocity was measured to ch

With today's increasingly competitive economy, many organizations have initiated customer relationship management (CRM) projects to improve customer satisfaction, revenue growth and employee productivity gains. However, only a few successful CRM implementations have successfully completed. In order to enhance the CRM implementation process and increase the success rate, in this paper, first we present the most significant success factors for CRM implementation identified by the results of litera

The use of COTS (commercial-off-the-shelf) components for system development has been a growing trend in the software engineering community during the past decade. However, the engineering of COTS-based systems involves significant technical risks. A good indicator of the as yet unresolved difficulties in COTS-based system developments is the relatively poor understanding frequently regarding the processes associated with development of the "glue code" used to integrate COTS components into the
