The impacts of quality and productivity perceptions on the use of software process improvement innovations

Numerous software process improvement (SPI) innovations have been proposed to improve software development productivity and system quality; however, their diffusion in practice has been disappointing. This research investigates the adoption of the Personal Software Process on industrial software projects. Quantitative and qualitative analyses reveal that perceived increases in software quality and development productivity, project management benefits, and innovation fit to development tasks, enhance the usefulness of the innovation to developers. Results underscore the need to enrich current technology acceptance models with these constructs, and serve to encourage project managers to adopt formal SPI methods if developers perceive the methods will have positive impacts on their productivity and system quality.

A parameter choice strategy for the regularized approximation of Fredholm integral equations of the first kind

Recently, Rajan [A Modified convergence analyis for solving Fredholm integral equations of the first kind, Integral Equ. Oper. Theory, 49 (2004), pp. 511–516.] suggested a modified convergence analysis for solving Fredholm integral equations of the first kind and also considered an a priori parameter choice strategy of choosing the regularization parameter. In this article, as an a posteriori parameter choice strategy for choosing the regularization parameter, a class of discrepancy principle is proposed under the Hilbert space setting and is illustrated numerically.     

Toward improved peptide feature detection in quantitative proteomics using stable isotope labeling

Reliable detection of peptides in LC-MS data is a key algorithmic step in the analysis of quantitative proteomics experiments. While highly abundant peptides can be detected reliably by most modern software tools, there is much less agreement on medium and low-intensity peptides in a sample. The choice of software tools can have a big impact on the quantification of proteins, especially for proteins that appear in lower concentrations. However, in many experiments, it is precisely this region of less abundant but substantially regulated proteins that holds the biggest potential for discoveries. This is particularly true for discovery proteomics in the pharmacological sector with a specific interest in key regulatory proteins. In this viewpoint article, we discuss how the development of novel software algorithms allows us to study this region of the proteome with increased confidence. Reliable results are one of many aspects to be considered when deciding on a bioinformatics software platform. Deployment into existing IT infrastructures, compatibility with other software packages, scalability, automation, flexibility, and support need to be considered and are briefly addressed in this viewpoint article.

A method to optimize the scope of a software product platform based on end-user features

ContextDue to increased competition and the advent of mass customization, many software firms are utilizing product families – groups of related products derived from a product platform – to provide product variety in a cost-effective manner. The key to designing a successful software product family is the product platform, so it is important to determine the most appropriate product platform scope related to business objectives, for product line development.AimThis paper proposes a novel method to find the optimized scope of a software product platform based on end-user features.MethodThe proposed method, PPSMS (Product Platform Scoping Method for Software Product Lines), mathematically formulates the product platform scope selection as an optimization problem. The problem formulation targets identification of an optimized product platform scope that will maximize life cycle cost savings and the amount of commonality, while meeting the goals and needs of the envisioned customers’ segments. A simulated annealing based algorithm that can solve problems heuristically is then used to help the decision maker in selecting a scope for the product platform, by performing tradeoff analysis of the commonality and cost savings objectives.ResultsIn a case study, PPSMS helped in identifying 5 non-dominated solutions considered to be of highest preference for decision making, taking into account both cost savings and commonality objectives. A quantitative and qualitative analysis indicated that human experts perceived value in adopting the method in practice, and that it was effective in identifying appropriate product platform scope.
