We have created a process model for managing corrective maintenance requests at the front-end support level. Our model is called CM3: front-end problem management. It was elicited at two ABB organisations and refined at Cap Gemini Ernst & Young and Scandinavian Airline Systems. In this paper, we evaluate it on a major scale using feedback from 15 major software organisations. The evaluation results...
It is known that well over 50% of replacement projects fail. Requirements gathering go someway to contributing to this statistic; if the requirements we gather for the new system do not match those of the system to be replaced then the project is bound to fail, at least in part. This paper proposes an empirical metric that assists measuring the confidence in the requirements extracted from a legacy...
Evolving software design is a critical activity for many reasons: inadequate documentation, loss of strategic knowledge due to personnel's turnover, intrinsic complexity of software design. As a consequence, performances in the evolution tasks may deteriorate. Some experiments demonstrate that pair programming is able to reduce the time spent for accomplishing the tasks while increasing the overall...
There are some concerns in the research community about the convenience of using low-level metrics (such as SLOC, source lines of code) for characterizing the evolution of software, instead of the more traditional higher lever metrics (such as the number of modules or files). This issue has been raised in particular after some studies that suggest that libre (free, open source) software evolves differently...
Design patterns are important in software maintenance because they help in designing, in understanding, and in re-engineering programs. The identification of occurrences of a design pattern consists in identifying, in a program, classes which structure and organisation match - strictly or approximately - the structure and organisation of classes as suggested by the design pattern. We express the problem...
It is observed that most object oriented coupling metrics are macroscopic, which makes them unsuitable for making finer refactoring decisions. The notions of microscopic viewpoints and coupling projections are introduced. Existing metrics are classified in terms of viewpoints and projections. Two microscopic metrics called relative method coupling (RMC) and relative inward coupling (RIC) are introduced,...
This paper describes a case study that uses clustering to group classes of an existing object-oriented system of significant size into subsystems. The clustering process is based on the structural relations between the classes: associations, generalizations and dependencies. We experiment with different combinations of relationships and different ways to use this information in the clustering process...
Database reverse engineering in general has only been used to recover the conceptual schema employed during its construction. To the best of our knowledge, none of this work has made use of that static structure to perform a deep analysis to infer functionality, or in other words, services over data that could be offered via Web services. Our work goes beyond the discovery of functionality, generating...
Software maintenance and reuse require identification of the applied software licenses. The information needs of maintainers and reusers can be supported by reverse engineering tools at different information retrieval levels. The paper presents a reverse engineering approach called ASLA for retrieving license information typically used in OSS. User needs, system architecture, tool features, and tool...
