Towards a scope management of non-functional requirements in requirements engineering
Getting business stakeholders’ goals formulated clearly and project scope defined realistically increases the chance of success for any application development process. As a consequence, stakeholders at early project stages acquire as much as possible knowledge about the requirements, their risk estimates and their prioritization. Current industrial practice suggests that in most software projects this scope assessment is performed on the user’s functional requirements (FRs), while the non-functional requirements (NFRs) remain, by and large, ignored. However, the increasing software complexity and competition in the software industry has highlighted the need to consider NFRs as an integral part of software modeling and development. This paper contributes towards harmonizing the need to build the functional behavior of a system with the need to model the associated NFRs while maintaining a scope management for NFRs. The paper presents a systematic and precisely defined model towards an early integration of NFRs within the requirements engineering (RE). Early experiences with the model indicate its ability to facilitate the process of acquiring the knowledge on the priority and risk of NFRs
Identifying and Modelling Complex Workflow Requirements in Web Applications
Workflow plays a major role in nowadays business and therefore its
requirement elicitation must be accurate and clear for achieving the solution
closest to business’s needs. Due to Web applications popularity, the Web is becoming
the standard platform for implementing business workflows. In this
context, Web applications and their workflows must be adapted to market demands
in such a way that time and effort are minimize. As they get more popular,
they must give support to different functional requirements but also they
contain tangled and scattered behaviour. In this work we present a model-driven
approach for modelling workflows using a Domain Specific Language for Web
application requirement called WebSpec. We present an extension to WebSpec
based on Pattern Specifications for modelling crosscutting workflow requirements

Early aspects: aspect-oriented requirements engineering and architecture design
This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a presentation session and working sessions in which the particular topics on early aspects were discussed. The primary goal of the workshop was to focus on challenges to defining methodical software development processes for aspects from early on in the software life cycle and explore the potential of proposed methods and techniques to scale up to industrial applications
Geant4-related R&D for new particle transport methods
A R&D project has been launched in 2009 to address fundamental methods in
radiation transport simulation and revisit Geant4 kernel design to cope with
new experimental requirements. The project focuses on simulation at different
scales in the same experimental environment: this set of problems requires new
methods across the current boundaries of condensed-random-walk and discrete
transport schemes. An exploration is also foreseen about exploiting and
extending already existing Geant4 features to apply Monte Carlo and
deterministic transport methods in the same simulation environment. An overview
of this new R&D associated with Geant4 is presented, together with the first
developments in progress.Comment: 4 pages, to appear in proceedings of the Nuclear Science Symposium

Detecting Conflicts and Inconsistencies in Web Application Requirements
Web applications evolve fast. One of the main reasons for this
evolution is that new requirements emerge and change constantly. These new
requirements are posed either by customers or they are the consequence of
users’ feedback about the application. One of the main problems when dealing
with new requirements is their consistency in relationship with the current
version of the application. In this paper we present an effective approach for
detecting and solving inconsistencies and conflicts in web software
requirements. We first characterize the kind of inconsistencies arising in web
applications requirements and then show how to isolate them using a modeldriven
approach. With a set of examples we illustrate our approach
Systems, interactions and macrotheory
A significant proportion of early HCI research was guided by one very clear vision: that the existing theory base in psychology and cognitive science could be developed to yield engineering tools for use in the interdisciplinary context of HCI design. While interface technologies and heuristic methods for behavioral evaluation have rapidly advanced in both capability and breadth of application, progress toward deeper theory has been modest, and some now believe it to be unnecessary. A case is presented for developing new forms of theory, based around generic “systems of interactors.” An overlapping, layered structure of macro- and microtheories could then serve an explanatory role, and could also bind together contributions from the different disciplines. Novel routes to formalizing and applying such theories provide a host of interesting and tractable problems for future basic research in HCI
Tracing the Scenarios in Scenario-Based Product Design: a study to support scenario generation
Scenario-based design originates from the human-computer interaction and\ud
software engineering disciplines, and continues to be adapted for product development. Product development differs from software development in the former’s more varied context of use, broader characteristics of users and more tangible solutions. The possible use of scenarios in product design is therefore broader and more challenging. Existing design methods that involve scenarios can be employed in many different stages of the product design process. However, there is no proficient overview that discusses a\ud
scenario-based product design process in its full extent. The purposes of creating scenarios and the evolution of scenarios from their original design data are often not obvious, although the results from using scenarios are clearly visible. Therefore, this paper proposes to classify possible scenario uses with their purpose, characteristics and supporting design methods. The classification makes explicit different types of scenarios and their relation to one another. Furthermore, novel scenario uses can be referred or added to the classification to develop it in parallel with the scenario-based design\ud
practice. Eventually, a scenario-based product design process could take inspiration for creating scenarios from the classification because it provides detailed characteristics of the scenario

On the design of systems-oriented university curricula
This paper proposes a tool called the Systems Education Matrix (SEM) for use in informing the work of developers of systems-oriented curricula at colleges and universities around the world. The SEM was developed by Team 1 at the 2008 IFSR Fuschl Conversation held at Fuschl am See in Austria. In order to manage the complex problems we are dealing with today, systems thinking is essential. It is clear that systems education should be acknowledged as an important 'scientific method' that can help today's society to deal with the complexities of contemporary issues. To serve this role effectively, systems education needs to be focused towards the various needs that exist. The members of Team 1 have focused on the nature of systems education that will be required to not only train systems specialists, but to make systems thinking and analysis an integral part of discipline focused research and management
