this paper claims that the design and construction of safety critical interactive systems require both a task centred approach to support efficiently operator's goals and activities and a system centred approach to increase the dependability of the system. the approach presented proposes a model-based approach integrating tasks and system models. this integration is done at the model level (in a similar way as in [13]) and at the tool level exploiting PetShop environment [3] for the system side and AMBOSS [1] for the task side. the tool level integration describes three different protocols each of them having advantages and limitations. the model-based approaches are introduced through a case study in the field of command and control systems. the application called AGENDA allows operators to define and organize work plan for satellite ground systems.

Software engineering and human-computer interaction communities use methods, techniques and tools that are not easily integrated. Our work argues that the development process could be improved by providing the designer withmodels, languages and tools that provides a seamless integration of software engineering and human-computer interaction approaches. In order to achieve this goal we have developed a language the Interactive Message Modeling Language (IMML) to support the development of interactive systems. this paper presents and discusses the concepts and modelsthat are the foundation of IMML. We also compare our process with traditional task-based perspectives.

the increasing importance of unstructured, knowledge-intensive processes in enterprises is largely recognized. Conventional workflow solutions do not provide adequate support for the management and optimization of such processes. therefore the need for more flexible approaches arises. this paper presents a conceptual framework for unobtrusive support of unstructured, knowledge-intensive business processes. the framework enables modeling, exchange and reuse of light-weight, user-defined task structures. In addition to the person-to-person exchange of best-practices, it further enables 'outsourcing' of dynamic task structures and resources in personal workspaces and organizational units where these are managed according to local domain knowledge and made available for reuse in shared repositories. the delegation of tasks enables the generation of enterprise process chains, spreading beyond the boundaries of a user's personal workspace. the structures emerging from user-defined tasks, task delegations and on-demand acquisition of dynamic, externally managed tasks and resources adequately represent agile, human-centric business processes. thereby the framework facilitates effective knowledge management and fosters proactive tailoring of underspecified business processes through end users in a light-weight, unobtrusive manner. the presented concepts are supported within the Collaborative task Manager (CTM), a novel prototype for email-integrated task management.

In this paper, we argue that the combination of task modeling with abstract prototyping improves the effectiveness of the userinterfacedesign at an early stage of the development process. Currently there is no effective way to connect popular task and presentation based formalisms (e.g. Concurtask Trees - CTTs and Canonical Abstract Prototypes - CAPs) in interactive system development. Here we present and illustrate an approach that relates CTTs with CAPs under the common semantics of the UML 2.0. We find that an abstract prototype is more suitable as a starting point to represent and infer the task structure that supports the user interaction. Our approach is supported by the DialogSketch tool, which enables the creation, design and editing of a UML version of CAPs and CTTs that can be co-edited and simulated in an innovative way that leverages effective and usable simulation of abstract user-interfaces.

In this paper, we describe the COMETS Inspector, a software tool providing userinterfacedesigners and developers with a semantic network in order to control the plasticity of their userinterfaces (UI) at run-time. thanks to a set of predefined relationships, the semantic network links together various concepts ranging from the final UI (i.e., the UI described in terms of technological spaces) to the concrete and abstract UIs (i.e., the UI respectively described in terms of concrete interaction objects independently of any technological space, and abstract individual components and containers independently of any interaction modality) up to the tasks and concepts of the interactive system. In this way, plasticity can be addressed at four levels of abstraction (task and concepts, abstract, concrete, and final userinterface) for forward, reverse, and lateral engineering. the end user exploits the semantic network at run time to adapt his/her UI to another context of use by identifying, selecting, and applying plasticity suitable operations.
