Process-Based Software Engineering: Building the Infrastructures

A recent trend in software engineering is the shift from a focus on laboratory-oriented software engineering to a more industry-oriented view of software engineering processes. This complements preceding ideas about software engineering in terms of organization and process-orientation. From the domain coverage point of view, many of the existing software engineering approaches have mainly concentrated on the technical aspects of software development. Important areas of software engineering, such as the technical and organizational infrastructures, have been left untouched. As software systems increase in scales, issues of complexity and professional practices become involved. Software development as an academic or laboratory activity, has to engage with software development as a key industrialized process.This expanded domain of software engineering exposes the limitations of existing methodologies that often address only individual subdomains. There is, therefore, a demand for an overarching approach that provide a basis for theoretical and practical infrastructures capable of accommodating the whole range of modern software engineering practices and requirements. One approach is provided by Process-Based Software Engineering (PBSE); part of the more general trend towards a focus on process.This paper provides a review of process techniques for software engineering and a high-level perspective on PBSE. Typical approaches and techniques for the establishment, assessment, improvement and benchmarking of software engineering process systems are introduced in this paper, and many are developed further in other contributions to this volume.

Developing a decision model for business process outsourcing

Information technology (IT) outsourcing has been one of the critical issues in organization management. Business process outsourcing (BPO) is an advanced type of IT outsourcing, which will be the next big wave in information technology services. Nevertheless, since prior studies have only examined issues related to traditional IS outsourcing, there have been few researches that introduce and discuss the important factors that should be considered in the decision of BPO adoption. This paper identifies factors affecting the BPO decision and structures a decision model using the analytic hierarchy process (AHP) method.By proposing a quantitative decision model, this paper will not only assist management in making better decisions in outsourcing their business processes, but also help them to obtain the most benefits from BPO.

Assessing PSP effect in training disciplined software development: A Plan-Track-Review model

Context

In training disciplined software development, the PSP is said to result in such effect as increased estimation accuracy, better software quality, earlier defect detection, and improved productivity. But a systematic mechanism that can be easily adopted to assess and interpret PSP effect is scarce within the existing literature.

Objective

The purpose of this study is to explore the possibility of devising a feasible assessment model that ties up critical software engineering values with the pertinent PSP metrics.

Method

A systematic review of the literature was conducted to establish such an assessment model (we called a Plan-Track-Review model). Both mean and median approaches along with a set of simplified procedures were used to assess the commonly accepted PSP training effects. A set of statistical analyses further followed to increase understanding of the relationships among the PSP metrics and to help interpret the application results.

Results

Based on the results of this study, PSP training effect on the controllability, manageability, and reliability of a software engineer is quite positive and largely consistent with the literature. However, its effect on one’s predictability on project in general (and on project size in particular) is not implied as said in the literature. As for one’s overall project efficiency, our results show a moderate improvement. Our initial finding also suggests that a prior stage PSP effect could have an impact on later stage training outcomes.

Conclusion

It is concluded that this Plan-Track-Review model with the associated framework can be used to assess PSP effect regarding a disciplined software development. The generated summary report serves to provide useful feedback for both PSP instructors and students based on internal as well as external standards.
