MOTIVATION Improving the usability of bioinformatics resources enables researchers to find, interact with, share, compare and manipulate important information more effectively and efficiently. It thus enables researchers to gain improved insights into biological processes with the potential, ultimately, of yielding new scientific results. Usability(More)
In this work we present the results of a study that has aimed at identifying the requirements for Web design methods that may influence the industrial acceptability, that is, the characteristics that prevent, or contribute to, the adoption of design methods in a business environment. The empirical study involved (by way of focus groups and surveys), over(More)
To be successful, any engineering product should accomplish the needs and expectations of its potential stakeholders. Similarly, design models should be defined taking into account goals and requirements of their users, i.e. the practitioners who daily conceive, develop and deploy applications. Neglecting stakeholders' needs can bring to lack of attention(More)
A possible measure of quality for any model or methodology is the degree of acceptance and usage. This paper discusses the factors that contribute to the industrial acceptability of conceptual models for web application design. We present an empirical study that examined 62 companies or institutions (in America and Europe) involved in large-scale web(More)
In this scenario the Sinfot Company, decided to migrate to the Web its legacy" ArcoImpresa" package. The job was done in co11aboration with our SEr-Lab. In the the paper we describe the ~thodological steps we adopted and the main technical issues we encountered" Abstract Various approache,y can be used to migrate legac,Y applications to the Web.

Who uses requirements engineering and design methodologies besides the people who invented them? Are researchers-at least-actually trying to use them in real-world complex projects and not in "paper project"? In this paper, we dare to recount the experience and the lessons we gained in trying to use seriously and in-depth a requirements engineering method(More)
In this paper we introduce the work done to define a framework for requirements and architectural understanding in biomedical grid computing systems. A set of core requirements for biomedical grids have been identified on the basis of our experience in the analysis and development of several biomedical and other grid systems including the National Cancer(More)
While most of the attention on building systems enabling semantic interoperability has been devoted to technical issues, human and organizational aspects are of equally if not higher importance. In this paper we focus on these aspects by recounting our experience and lessons learned working to the development of an innovative system in the cancer research(More)
