Process- and task-driven workflow support has become vital for enterprises as they operate in an increasingly networked business environment. thereby business process specifications represent boundary objects not only between different organizational units, but also between technology and business operations. Process specifications need to be integrated and implemented in a flexible way for actual work-task support. Although several business process techniques and technologies are in place there are still several transformational steps to be performed when implementing business operations based on detailed work descriptions. One effective way to prevent incoherencies is role-specific and task-driven modeling, representation, and processing of business operations. the introduced approach is termed subject-oriented business process management, as it ensures coherence between modeling and execution through focusing on the communication flow among process participants (subjects) in the course of work-task accomplishment.

this paper describes an approach to adapt the use-case point estimation method to lit the requirements of agile development of interactive software. Creating product cost estimates early in the development lifecycle is a challenge for the software industry, they require substantial data from past projects and constant feedback and fine-tuning, which are rarely available or consistent through interactive software development. In addition, the profusion of incremental and evolutionary development methods (like Scrum and XP) produced new challenges with estimating frequent releases. Here we propose several changes to the original use-case point estimation method, in particular to take advantage of the enhanced information that can be extracted from usage-centered design (usageCD) that devotes particular attention to critical aspects like weighting actors and uses-cases for complexity. We propose to exploit user-roles, essential use-cases and the usageCD architecture to enhance the weighting heuristics for assigning complexity factors to actors and use-cases required to calculate the unadjusted use-case point reflecting the complexity of the requirements for a given iteration or evolution. We propose to exploit user-roles as the main basis for weighting complex actors, which originally are grouped in the highest weight factor. Conversely we propose to extract the complexity of use-cases from essential use case steps depicted through user intentions and system responsibilities and also the analysis classes extract from those for the usageCD architecture. Detailing this approach the paper presents a contribution, not only to leverage more accurate early lifecycle software estimation, but also to bridge the gap between SE and HCI enabling cross-fertilization between the two disciplines.

In the field of model-based userinterfacedesign (MB-UID) task modeling is established as a necessary activity. However, in many (industrial) contexts, it is not realistic to introduce yet another modeling notation, particularly when userinterfacedesign is considered less important than overall process logic and system architecture. therefore, it may make more sense to adapt existing process-oriented notations to task modeling, than vice versa (adapting task modeling languages to process modeling). this paper describes our experiences with using BPMN and Diamodl for process and task modeling and dialog design, respectively.

the context of this work is usability engineering for mutimodal interaction. In contrast to other work that concentrates on prototyping toolkits or abstract guidelines, this research focuses on userinterface patterns for multimodal interaction. designing multimodal applications requires several skills ranging from design and implementation. thus, different kinds of patterns (from architecture patterns to userinterface patterns) can be applied to this field. this work focuses on user-task near userinterface patterns. At first, a traditional approach of modality selection based on task- and context-based rules is presented. Next, a twofold process of pattern mining is presented. In the first phase, pattern candidates are derived top-down from proven knowledge about how multimodality enhances usability. In the second phase, literature is mined for real solutions to underpin these pattern candidates and find new ones. Along withthis, relationships between patterns are depicted.

Digital tabletops are emerging interactive systems that support group collaborations. To utilize digital tabletops for agile planning meetings, we migrated a desktop based planning tool - AgilePlanner to a digital tabletop. this paper reports on challenges of the migration and illustrates differences between user interactions on a digital tabletop and on a desktop. Moreover, lessons and experiences learnt from our design process are highlighted to facilitate future tabletop application design.
