The potential benefits of EPGs can only be realized when key capabilities are not only adopted, but also infused across the organization. We conducted a survey of 97 software developers in a medium-sized software company to test the importance of organizational support and four factors on the perceived attributes of using the EPG to its infusion. The results showed that perceived usefulness is the fundamental driver in explaining current system usage and future use intentions, and furthermore, that perceived compatibility, perceived ease of use, and organizational support were the key determinants of perceived usefulness. This study advances our understanding of software developers' acceptance and utilization of EPGs in a voluntary setting. This way, software organizations can learn more about the determinants of successfully adopting and infusing EPGs and, accordingly, to take more appropriate actions.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

No matter what approach one is using to study such evolution, empirical studies, including observations of systems used in the real world, and of their processes, are needed in order to define correlations, find recurring patterns, and eventually predict how systems are likely to evolve. In the empirical study presented in this paper, we take 25 software systems released as open source, and observe their evolution. Our focus is not only on how much systems grow in size, but rather on how code structure is adapted and gets modified over time and releases. The goal here is to recognize recurring patterns and practices used in evolving long-lived real world software systems. In our study we find three dominant patterns of code structure evolution of open source systems: horizontal expansion, vertical expansion, vertical shrinkage By detailed studied of exemplars of these three patterns one can identify under which conditions a particular pattern is more likely to prevail than the others.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

This approach can be generalized to a probabilistic version using Monte Carlo methods to produce estimates of size distributions. The probabilistic pairwise comparison technique enables the estimator to systematically incorporate both estimation uncertainty as well as any uncertainty that arises from using multiple historical analogies as reference modules. In addition to describing the methodology, the results of the case study are also included. This paper is an extension of the work presented in [Lum, K et al., (2003)] and shows how the original software size estimates compared to the actual delivery size. It also describes the techniques used to modify the approach based on lessons learned. The results because they are based on only one case do not validate the effectiveness of the proposed approach but are suggestive that the technique can be effective and support the conclusion that further research is worth pursuing.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

Architectural attributes differ from code-level software attributes in that they focus on the level of components and connectors, and that they are meaningful for an architecture. In this paper, we focus on a specific architectural attribute, which is the error propagation probability throughout the architecture, i.e. the probability that an error that arises in one component propagates to other components. We introduce, analyze, and validate formulas for estimating these probabilities using architectural level information.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

Several empirical studies have been performed on reading techniques, which are used in the individual preparation phase of software inspections. Besides new experiments, replications are needed to increase the body of knowledge in software inspections. We present a replication of an experiment, which compares usage-based and checklist-based reading. The results of the original experiment show that reviewers applying usage-based reading are more efficient and effective in detecting the most critical faults from a user's point of view than reviewers using checklist-based reading. We present the data of the replication together with the original experiment and compares the experiments. The main result of the replication is that it confirms the result of the original experiment. This replication strengthens the evidence that usage-based reading is an efficient reading technique.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

With missing data, statistical tests will lose power, results may be biased, or analysis may not be feasible at all. There are several ways to handle the problem, for example through imputation. With imputation, missing values are replaced with estimated values according to an imputation method or model. In the k-nearest neighbour (k-NN) method, a case is imputed using values from the k most similar cases. In this paper, we present an evaluation of the k-NN method using Likert data in a software engineering context. We simulate the method with different values of k and for different percentages of missing data. Our findings indicate that it is feasible to use the k-NN method with Likert data. We suggest that a suitable value of k is approximately the square root of the number of complete cases. We also show that by relaxing the method rules with respect to selecting neighbours, the ability of the method remains high for large amounts of missing data without affecting the quality of the imputation.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

Related literature has focussed on developing new classification techniques and schemes with the aim of improving classification accuracy. However, the quality of software measurement data used to build such classification models plays a critical role in their accuracy and usefulness. We present empirical case studies, which demonstrate that despite using a very large number of diverse classification techniques for building software quality classification models, the classification accuracy does not show a dramatic improvement. For example, a simple lines-of-code based classification performs comparatively to some other more advanced classification techniques such as neural networks, decision trees, and case-based reasoning. Case studies of the NASA JM1 and KC2 software measurement datasets (obtained through the NASA Metrics Data Program) are presented. Some possible reasons that affect the quality of a software measurement dataset include presence of data noise, errors due to improper software data collection, exclusion of software metrics that are better representative software quality indicators, and improper recording of software fault data. This study shows, through an empirical study, that instead of searching for a classification technique that perform well for given software measurement dataset, the software quality and development teams should focus on improving the quality of the software measurement dataset.","PeriodicalId":261807,"journal":{"name":"10th International Symposium on Software Metrics, 2004.

We have re-engineered a subsystem of a large enterprise communications product. The subsystem implements a standards-based communication protocol with numerous proprietary extensions. Due to many enhancements which the code has undergone, it showed clear signs of design degradation. The business purpose of the re-engineering project was to improve intelligibility and changeability of the code without changing or breaking existing functionality and without imposing a significant performance penalty. We used the re-engineering effort as experimental context for evaluating the enabling technologies.

This case study of the FreeBSD project provides further understanding of open source development. The FreeBSD development process is fairly well-defined with proscribed methods for determining developer responsibilities, dealing with enhancements and defects, and for managing releases. Compared to the Apache project, FreeBSD uses a smaller set of core developers that implement a smaller portion of the system, and uses a more well-defined testing process. FreeBSD and Apache have a similar ratio of core developers to (1) people involved in adapting and debugging the system, and (2) people who report problems.
