Software Process and Product Measurement

This book constitutes the thoroughly refereed post-proceedings of the International Workshop on Software Measurement, IWSM-Mensura 2007, held in Palma de Mallorca, Spain, in November 2007. The 16 revised full papers presented were carefully reviewed and selected for inclusion in the book. The papers deal with aspects of software measurement like function-points measurement, effort and cost estimates, prediction, industrial experiences in software measurement, planning and implementing measurement, measurement-based software process improvement, best practices in software measurement, usability and user interaction measurement, measurement of open source projects, teaching and learning software measurement as well as new trends and ontologies for software measurement.

An Empirical Analysis of Object-Oriented Metrics for Java Technologies

As a fact, the application of object-oriented approach is of high significance in the area of software development since it can abet efficiency or cost effectiveness and reduce error probability during software design and implementation. In order to quantify, especially qualitative aspects such as potential error hot spots caused by elevated design complexity, software measurement can strongly assist. Particularly, metrics proposed by Chidamber and Kemerer as well as Abreus MOOD metrics set are presumably most prevalent in practice and provide adequate explanatory power. Especially the object-oriented programming language Java cannot be dismissed from ones thoughts because a lot of Java libraries serve as foundation for contemporary applications. Thus, after initially defining language bindings for the aforementioned metrics, we perform measurement and evaluation of various Java standard libraries like J2SE, J2EE, J2ME, JWSDP and few others concerning different aspects. The results acquired are beneficial to be used by software designers for aligning and orienting their design with common industry practices. Furthermore, our extensive measurements enable us to carry out key metrics correlation studies incorporating many thousand Java classes

Quality-Driven Orchestration of Services

The importance of providing integration architectures in every field of application is beyond controversy these days. Unfortunately existing solutions are focusing mainly on functionality. But for the success of Systems Integration in the long run, the quality of developed architectures is of substantial interest. Therefore a framework for quality-driven creation of architectures is proposed in this paper. Besides these quality-oriented characteristic the usage of semantic knowledge and structured process descriptions enable an automatic procedure. Especially the combination of both is a promising approach.

A Metrics Data Base Maturity Model

The prominence of measurement and assessment of software development artifacts is beyond controversy, these days. To expand insular measurement to empirical series of measurement and thus to benefit from it in the long-run, a qualified measurement collection process is almost compulsory. Even though renowned measurement guidance recommends the usage of metrics data bases (MDB), it does not assist in their design or implementation. This paper is therefore intended to address the question of: which aspects account for mature and meaningful MDB? Based on an investigation in factors influencing an MDBs maturity, we introduce a first approach towards a MDB maturity model (MDBMM ) to appraise the maturity of an organizations measurement collection process with the aid of a five level ordinal scale
