ABSTRACT:In this work we present the results of a study 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 100 potential users of Web design methods including project managers, analysts, information architects, visual designers, implementers, recruited from companies and non academic institutions intensively involved in the development of Web based applications. Our study has gathered qualitative and quantitative information that highlight expectations and needs of stakeholders of Web design methods. It has highlighted that usability, modularity, scalability, customizability, support to fast prototyping and incremental development, support to design-related activities (training, project management, design documentation delivery) are critical requirements for a design method to be adopted in the industrial practice. To define our study, we have adopted a holistic perspective. We have investigated requirements looking at design methods as to engineering products that should work within the overall development process in which design occurs, and within the organizational context in which this process takes place.

ABSTRACT: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 (called AWARE) combined with a conceptual
user-centered design method (called W2000) for the
development of a real-world web application. The
project is recounted through the process followed and
the artefacts produced, as well as by crystallizing our
experience in using and transferring the method to
industry in practical and methodological
recommendations.

ABSTRACT:This chapter defines a publishing model for Web applications starting from
the analysis of the most well-known modeling methodology, such as HDM,
OOHDM, WebML, Conallen’s method and others.
The analysis has been focused to verify the state of art about the
modeling of Web application pages. In particular, the different types of
elements that compose the Web page in the above models are taken into
consideration.
This chapter describes the evolution of the HDM methodology starting
from the first approach based on the definition of a LP concept up to the more
structured and complex Conceptual page, based on the influence of
“operations” on the modeling of the dynamics of navigation between pages.

ABSTRACT: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 Institute’s Early
Detection Research Network (EDRN) in the US and the
National Cancer Research Institute (NCRI) Platform in
the UK. The requirements have been specified taking into
account different points of view and are intended as a
core set that can be extended on the basis of project
specific aspects. These are also mapped to existing
architectures of biomedical grid systems, and their
constituent components. Such a framework is intended as
a guide for equipping developers with conceptual tools to
avoid costly mistakes when architecting biomedical grid
systems.

ABSTRACT: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
domain.

ABSTRACT:The NCRI Informatics Initiative has been established with the goal of using informatics to
maximise the impact of cancer research. A clear foundation to achieving this goal is to
enable the development of an informatics platform in the UK that facilitates access to, and
movement of, data generated from research funded by NCRI Partner organisations, across
the spectrum from genomics to clinical trials. To assure the success of such a system, an
initial project has been defined to establish and document the requirements for the platform
and to construct and validate the key information models around which the platform will be
built. The platform will need to leverage many projects, tools and resources including those
generated by many e-Science projects. It also required contributing to the development of a
global platform through a close interaction with similar efforts being developed by the NCI
in the USA. This paper recounts our experience in analysing the requirements for the
platform, and explains the customised analysis approach and techniques utilised in the
project.

ABSTRACT: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 towards these engineering products
(design models) while fitness to requirements can drastically
increase their acceptability in the real world. This paper focuses on
the domain of Communication and Interaction Intensive
applications (C&II applications) by presenting a suite of two
conceptual models (namely IDM and E-WOOD) belonging to a
more comprehensive methodological framework addressing the
analysis and design of such a kind of applications. The focus of the
paper is not on the presentation of the methods but on highlighting
their fitness to the requirements of the potential adopters of such
methods. To this end, the overall framework has been defined on
the basis of an accurate analysis of potential stakeholders’ goals and
requirements gained from our training experience to professional
designers and from adoption of our previous conceptual methods in
several real-life projects.

ABSTRACT:In this paper we recount the experience and the
lessons we learned trying to use concretely and in-depth
a requirements engineering method (called AWARE)
combined with a conceptual user-centered design method
(called W2000) for the development of the Institutional
website of the Superior Council for Public Works of the
Ministry of Infrastructure and Transportation in Italy.
The project is framed within its contractual context, and
discussed through the process followed and the artifacts
produced during requirements analysis and design.
Lessons learned are depicted from a twofold perspective.
From the one side they crystallize insights from the
research experience of using and transferring the
methods to industry, suggesting practical and
methodological recommendations. From the other they
express what a medium-size software company has
experienced trying to use academic methods.

ABSTRACT:In this paper we introduce our framework for
supporting the entire development of interaction and data
intensive (typically Web) applications and describe one of
the composing methods addressing the design of the user
experience. Current proposals, both in the academic and
industrial communities addressing such a kind of
application, exhibit different weaknesses and strengths
but are both characterized by poor acceptance by the
current practice. Instead of proposing a new, richer
modelling method, we have extracted and reused what
good has been done in both the academic and industrial
worlds in order to meet potential stakeholders’
requirements. The whole approach has been shaped by
the domain analysis and addresses the development of
Web applications from requirements elicitation/analysis
to software design in four phases. One of these phases,
the user experience design named E-WOOD, is here detailed.
Its specific stakeholders and requirements are here
described. E-WOOD extends a UML proposal, coming
from the industrial world, reusing web engineering
principles coming from the academic experience. It
introduces a reasoning oriented, user centered semantics
which can be used for designing application better fitting
stakeholders’ goals and closer to final user expectations.

ABSTRACT:The aim of DICE is the improvement of communication between culture-providers
(institutions, museums, etc.) and different categories of users (scholars, publishers, culturaltourism
promoters, etc.), trying to “ translate ” into a common vocabulary the patrimony of
content held by each source of information. The result is a shared virtual space, allowing access
to different sources of information, integrated in a peer-to-peer philosophy, in order to create an
effective working environment for professional users.
DICE provides a technical infrastructure, a software platform, an organizational and
cultural model, with a flexible and scalable approach that allows the collection of information
from all the actors involved.

ABSTRACT:Modern web sites are more and more including complex business processes closely related to the core business of
proponent companies. Processes manage resources (books, cars, train tickets, flight reservation, etc.) closely related
to the core business of proponent companies and their execution is constrained by the underlying business logic and
architecture. Web processes are executed by means of a web application which has to obey to the navigational
interaction paradigm. These three characteristics of web business processes raise a number of usability issues up yet
uncovered by existing usability methods. This paper introduces a set of heuristics, abstract tasks and a novel
inspection method (named PUW) which enable usability experts to analyze the effectiveness of information and
navigation provided to support the resource management and process workflow execution. Compared to existing
inspection methods, the approach steps over addressing entire process execution usability instead of focusing on its
composing pages by their own.

ABSTRACT:This paper summarizes the main achievements of a research whose main goal has been to investigate the current state-of-art in the field of requirements engineering for COTS-based systems. The most relevant contributions in this field in the past 10 years have been reviewed. From this analysis, we have defined a scenario composed by a number of punctual but relevant contributions and a number of methodological approaches addressing the requirements analysis and specification of such systems. Finally, on the basis of this scenario, a Wish List of desirable features of a hypothetical approach has been defined and compared against the current situation. This list may act as an empirical means for evaluating new approaches addressing RE for COTS-based systems, and bases its foundations on the current needs pointed out by the major experts in this field.

ABSTRACT: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 application development. By
investigating the “desiderata” of industrial “practitioners” (developers,
designers, or project managers of web applications), we aimed at identifying the
requirements that a web design model should satisfy in order to be accepted and
used at industry level. The paper describes the design of the study and its main
results.

ABSTRACT:Web applications have become more complex blending together several different features: navigation paradigms to browse across information, operations to manipulate data and to perform actions, interactivity, full-fledged transactions, etc. In addition the need to consider several possible devices (including mobile ones and interactive TV), as ways for to user to access the “same application ” and the fact that different user categories need to share the same applications, make the picture even more complex.
Current design methodologies are not satisfactory, since they tackle one piece of the problem (e.g. hypertext features, or transactions, or operations, or data), but they do not cover the whole application.
This paper introduces an innovative design methodology from the UWA project, covering a broad spectrum of features, and based upon UML notation. A “real life” case study (in the Banking sector) is used as an example.

ABSTRACT:Web Applications are progressively becoming multi-channel and
cross-channel. The “ same ” service should be made available in
different delivery environments and devices. A user may invoke a
service on one device, suspend it, and complete its execution in
another one. In this paper we provide the reader with the main
concepts and innovative aspects of MC2 a design framework for
specifying Multi/Cross Channel web application services . MC2
adopts an high-level, end user perspective and exploits the notion
of context , to characterize who, where and how an operation can
be invoked.

ABSTRACT:Various approaches can be used to migrate legacy
applications to the Web. In particular, migrating dataintensive
legacy applications (e.g. traditional
application for business management) needs
methodological approach to face the challenges implied
by the process.
The Ubiquitous Web Applications (UWA) framework
is one of the most innovative and complete frameworks for
conceptual user centered modelling of a Web application.
In this paper we describe the application of UWA to a
real experience of reengineering a real legacy
application for customer’s order management.

ABSTRACT:The research we present in this paper is the result of the conjunct work of the authors in their own research areas. In the first part we analyze and compare different approaches for the problem of the migration of legacy data-intensive applications to the web and towards Application Service Providing (ASP) paradigm, and in the second part we illustrate the approach we have elaborated and experimented in a real project. The approach handles the migration problem by applying a framework for technological solutions selection and a customised approach to web application design based on a methodology for web application design named W2000. In addition, the most relevant concepts we show in this paper have been tested in a tangible experience in a research project dealing with the migration of a legacy application used for customer management software (CMS), providing a useful feedback for future improvements.
