“…An increasing understanding exists that empirical studies are needed to create, improve, or assess processes, methods, and tools for software development [Basili et al 1986;Basili 1996;Fenton 1993], maintenance [Colosimo et al 2009;Dzidek et al 2008], and quality evaluation [Bolchini and Garzotto 2007]. An empirical study is generally an act or operation by which to discover something that is unknown, or to test hypotheses [Basili 1993].…”

Web applications should be usable in order to be accepted by users and to improve the success probability. Despite the fact that this requirement has promoted the emergence of several usability evaluation methods, there is a need for empirically validated methods that provide evidence about their effectiveness and that can be properly integrated into early stages of Web development processes. Model-driven Web development processes have grown in popularity over the last few years, and offer a suitable context in which to perform early usability evaluations due to their intrinsic traceability mechanisms. These issues have motivated us to propose a Web Usability Evaluation Process (WUEP) which can be integrated into model-driven Web development processes. This paper presents a family of experiments that we have carried out to empirically validate WUEP. The family of experiments was carried out by 64 participants, including PhD and Master's computer science students. The objective of the experiments was to evaluate the participants' effectiveness, efficiency, perceived ease of use and perceived satisfaction when using WUEP in comparison to an industrial widely-used inspection method: Heuristic Evaluation (HE). The statistical analysis and meta-analysis of the data obtained separately from each experiment indicated that WUEP is more effective and efficient than HE in the detection of usability problems. The evaluators were also more satisfied when applying WUEP, and found it easier to use than HE. Although further experiments must be carried out to strengthen these results, WUEP has proved to be a promising usability inspection method for Web applications which have been developed by using model-driven development processes.

“…Community's experience confirms that SOA and Web Services are a right target for migrating legacy systems, specially when loose coupling among providers' and clients' systems, and agility to respond to changes in requirements [1] are needed [2,3,4]. The reported experiences show two main migration approaches, namely Direct and Indirect Migration [2].…”

“…With the top-down approach, 104 data-types represented business objects, including 39 simple types (mostly enumerations) and 65 complex types, in addition 131 data-types were needed for making WSDL documents compliant with the document/wrapped standard structure -this means, a message formed by one element-, which is recommended by the Web Service Interoperability standards (WS-I) 4 . For example, the Cuil data-type, which represents a business object that is analogous to the Social Security Number in the United States, is defined in the shared XSD schema as a complexType, but also wrapped by an element in the WSDL documents.…”

Moving from mainframe systems to Service-Oriented Architecture (SOA) using Web Services is an attractive but daunting task. The bottom-up or Direct Migration approach enables the e↵ective modernization of legacy systems to Web Services. Conversely, bringing migration into fruition with the top-down or Indirect Migration approach is recognized as being comparatively harder but achieves better migration results. In practice, it is very uncommon to employ both approaches to the same large enterprise system, which leaves no room for comparison. This paper reports the outcomes of applying both migration approaches on a real COBOL system, presents the followed migration processes, their costs, and reports on the discoverability and reusability of target Web Services.

Abstract-The evolution of Software Product Lines (SPL) is challenging because stakeholders have to deal with both regular evolution and the co-existence of different products. Our focus of product evolution is on the tasks integrators have to perform to update deployed SPL products with minimal interruption of services. In case of Egemin, our industrial partner, the updates of SPL products is further hampered as a consequence of outdated and imprecise architectural knowledge of deployed products. To facilitate the updates of products, we have developed the architecture-centric approach which comprises two complementary parts: an update viewpoint and a supporting tool.In this paper we present an evaluation of the architecturecentric approach. The approach is compared with the Egemin's current update approach in a controlled experiment. In the experiment 17 professionals were asked to perform 68 updates of logistic systems. The results obtained from the experiment show that the architecture-centric approach significantly improves the correctness of updates and reduces the interruption of services during updates of Egemin's SPL products.
