The Internet and WEB pervasivenesses are changing the landscape of several different areas, ranging from information gathering/managing and commerce to software development, maintenance and evolution. Software companies having a geographically distributed structure, or geographically distributed customers, are adopting information communication technologies to cooperate. Communication technologies and infrastructures allow the companies to create a virtual software factory. This paper proposes to adopt queue theory to deal with an economically relevant category of problems: the staffing, the process management and the service level evaluation of massive maintenance projects in a virtual software factory. Data from a massive corrective maintenance intervention were used to simulate and study different service center configurations, in particular, a monolithic configuration and a configuration corresponding to a multi-phase maintenance process where several maintenance centers cooperated. Queue theory allowed effective control of the process supporting project management decisions. The mathematical tool provided a means to assess staffing, evaluate service level and balance the workload between maintenance centers while executing the project.

The year 2000 problem posed a difficult problem for many IT shops world wide. The most difficult part of the problem was not the actual changes to ensure compliance, but finding and classifying the data fields that represent dates. This is a problem well suited to design recovery. The paper presents an overview of LS/2000, a system that used design recovery to analyze source code for year 2000 risks and guide a source transformation that was able to automatically remediate over 99% of the year 2000 risks in over three billion lines of production IT source.

In this paper an abstract of the Ph.D. thesis discussed at the University of Florence by the author is presented. The main focus of the thesis was in the identification and validation, both theoretical and empirical, of Object-Oriented metrics for complexity, and then, effort estimation. Complexity/effort metrics have been validated against test cases for verifying effectiveness of the estimation for evaluating development and maintenance effort.

Language conversion is a laborious process. Achieving the maximum efficiency of conversion without compromising the quality of converted system is the programmers' dream. This paper illustrates the quest for this trade-off by a case study. We consider an industrial reengineering project, which included translation of a client/server system written in a proprietary language into two different programming languages. We also discuss various factors that affect the automation level of language conversions.

The paper describes an architecture for multi-channel and multi-modal applications. First the design problem is explored and a proposal for a system that can handle multi-modal interaction and delivery of Internet content is proposed. The focus is pertained in some development aspects and the way they are addressed by using state-of-the-art tools. The various components are defined and described in detail. Finally, conclusions and a view of future work on the evolution of such systems is given.

Software organizations are moving from traditional software factory models towards virtual organization models, where distributed teams converge in a temporary network with the aim of integrating different competences or solving problems in a cooperative way. Most workflow management systems of last generation are web based and this makes them a viable enabling technology for remodeling both the organization structure and its processes in order to move towards a virtual organization model and increase its competitiveness. We present a case study of introducing workflow technologies in a large software enterprise. In particular, a workflow-based prototype implementation for the management of the ordinary maintenance process is discussed.

From the perspective of maintenance, software systems that include COTS software, legacy, ported or outsourced code pose a major challenge. The dynamics of enhancing or adapting a product to address evolving customer usage and the inadequate documentation of these changes over a period of time (and several generations) are just two of the factors which may have a debilitating effect on the maintenance effort. While many approaches and solutions have been offered to address the underlying problems, few offer methods which directly affect a team's ability to quickly identify and prioritize actions targeting the product which is already in front of them. The paper describes a method to analyze the information contained in the form of defect data and arrive at technical actions to address explicit product and process weaknesses which can be feasibly addressed in the current effort. The defects are classified using Orthogonal Defect Classification (ODC) and actual case studies are used to illustrate the key points.

Component based software technologies are viewed as essential for creating the software systems of the future. However, the use of externally-provided components has serious drawbacks for a wide range of software engineering activities, often because of a lack of information about the components. Previously (A. Orso et al., 2000), we proposed the use of component metacontents: additional data and methods provided with a component, to support software engineering tasks. The authors present two new metacontent based techniques that address the problem of regression test selection for component based applications: a code based approach and a specification based approach. First, we illustrate the two techniques. Then, we present a case study that applies the code based technique to a real component based system. On the system studied, on average, 26% of the overall testing effort was saved over seven releases, with a maximum savings of 99% for one version.

Many software engineering tools such as program slicers must perform data-flow analysis in order to extract necessary information from the program source. These tools typically borrow much of their implementation from optimizing compilers. However, since these tools are expected to analyze programs in their entirety, rather than functions in isolation, the time and space performance of the dataflow analyses are of major concern. We present techniques that reduce the time and space required to perform dataflow analysis of large programs. We have used these techniques to implement an efficient program slicing tool for C programs and have computed slices of programs with more than 100,000 lines of code.

Program refactoring-transforming a program to improve readability, structure, performance, abstraction, maintainability, or other features-is not applied in practice as much as might be desired. One deterrent is the cost of detecting candidates for refactoring and of choosing the appropriate refactoring transformation. This paper demonstrates the feasibility of automatically finding places in the program that are candidates for specific refactorings. The approach uses program invariants: when a particular pattern of invariant relationships appears at a program point, a specific refactoring is applicable. Since most programs lack explicit invariants, an invariant detection tool called Daikon is used to infer the required invariants. We developed an invariant pattern matcher for several common refactorings and applied it to an existing Java code base. Numerous refactorings were detected, and one of the developers of the code base assessed their efficacy.
