Performance Calculation and Benchmarking using the ISBSG Release 10 Data Repository

چکیده
Traditional benchmarking models in software engineering are typically based on the concept of productivity, first defined as a single ratio of output to input, and then combined with various cost factors leading to a single value. By contrast, the concept of performance is more comprehensive than productivity, and can handle other dimensions as well, like quality. Multidimensional models, such as those in the QEST/LIME family, are therefore necessary to adequately represent performance. In software engineering, software process improvement models typically treat productivity and performance as two distinct concepts, and at two distinct maturity levels and in distinct process areas. This paper explores how information from a comprehensive measurement program can be used to analyse performance. The project repository of the International Software Benchmarking Standards Group – ISBSG – is used as a case study to illustrate various aspects of the multi-dimensional QEST-LIME performance model.

Exploring the Relation Between Effort and Duration in Software Engineering Projects
This paper presents a confirmatory analysis of empirical models that predict software engineering project duration based on project effort, based on a more recent and much larger sample. The models are based on the analysis of project data provided by release 4 of the International Software Benchmarking Standards Group (ISBSG) repository. Duration models are built for subsets of projects using ...

متن کاملEmpirical findings on team size and productivity in software development
The size of software project teams has been considered to be a driver of project productivity. Although there is a large literature on this, new publicly available software repositories allow us to empirically perform further research. In this paper we analyse the relationships between productivity, team size and other project variables using the International Software Benchmarking Standards Gr...
