Stakeholder collaboration

Martin Nussbaumer, Patrick Freudenstein, Martin Gaedke
2006 Proceedings of the 6th international conference on Web engineering - ICWE '06  
Establishing efficient and intensive stakeholder collaboration is a key factor in Web application development projects. Therefore, the form of collaboration needs to be shifted from simple conversation to valuable contribution, i.e. empowering stakeholders to directly contribute to the development effort. To achieve this, we introduce an approach combining Domainspecific Languages and an underlying technical platform.

Towards DSL-based web engineering

Martin Nussbaumer, Patrick Freudenstein, Martin Gaedke
2006 Proceedings of the 15th international conference on World Wide Web - WWW '06  
Strong user involvement and clear business objectives, both relying on efficient communication between the developers and the business, are key factors for a project's success. Domain-Specific Languages (DSLs) being simple, highly-focused and tailored to a clear problem domain are a promising alternative to heavy-weight modeling approaches in the field of Web Engineering. Thus, they enable stakeholders to validate, modify and even develop parts of a distributed Web-based solution.

Constructing Advanced Web-Based Dialog Components with Stakeholders – A DSL Approach

Patrick Freudenstein, Martin Nussbaumer
2008 2008 Eighth International Conference on Web Engineering  
Complex dialogs with comprehensive underlying data models are gaining increasing importance in today's Web applications. This in turn accelerates the need for highly dynamic dialogs offering guidance to the users and reducing cognitive overload. Beyond that, requirements from the fields of Web accessibility, platform-independence and Web service integration arise. Considering the resulting complexity, a systematic engineering approach becomes important. Besides addressing the specific

To this end, we present an evolutionary, extensible approach for the model-driven construction of advanced dialogs which is based on a Domain-specific Language (DSL). We introduce a modeling notation based on Petri net constructs and XForms as well as a supporting Webbased editor, both focusing on simplicity and fostering communications. The technical framework allows for quick prototyping and flexible changes. In conclusion, complex, device-independent dialogs with rich behavior and appearance can be constructed and evolved with intense stakeholder collaboration.

Strengths and weaknesses of WS-BusinessActivity for cross-organizational SOA applications

Frederic Wenzel, Patrick Freudenstein, Martin Nussbaumer
2009 2009 ICSE Workshop on Principles of Engineering Service Oriented Systems  
In traditional database-driven applications, transactional integrity is a well-established concept. In order to apply these techniques to SOA-based applications, along with the capability to perform long-running business activities, the WS-BusinessActivity standard was developed. This standard does not specifically address cross-organizational use, however, when an enterprise decides to integrate its SOA-based system with their business partners' services, the ability to span long-running

Efficacious Reuse Support as Enabler for Cross-Methodological Web Engineering with Stakeholders

Patrick Freudenstein, Marko Boettger, Martin Nussbaumer
2008 2008 Eighth International Conference on Web Engineering  
As well as in traditional software engineering, reuse is a key factor for the efficient and efficacious construction and evolution of complex Web applications. Efficaciously integrated in the development process and supported by an appropriate framework, reuse significantly increases development speed, application quality and, by enabling rapid prototyping, improves stakeholder communications. Although reuse aspects in traditional software engineering have been thoroughly investigated, their

Beyond that, current consolidation activities in the Web Engineering community underline the significance of a unifying solution. To this end, we present a comprehensive ontology-based Web Engineering reuse approach that establishes a common basis for cross-methodology reuse strategies and emphasizes stakeholder collaboration. To unfold the full potential of reuse, it incorporates both planned and spontaneous reuse strategies. We point out the approach's extensibility and applicability for cross-methodological Web Engineering and demonstrate how it considerably accelerates development speed and improves stakeholder communications.

A Workflow-Driven Approach for the Efficient Integration of Web Services in Portals

Patrick Freudenstein, Martin Nussbaumer, Frederic Majer, Martin Gaedke
2007 IEEE International Conference on Services Computing (SCC 2007)  
As Service-oriented Architectures (SOA) mature, an efficient approach for the integration of Web services in portals is required. This holds true especially in medium and large-scale SOA-based systems with a multitude of Web services to be made accessible to the users. The integration scenarios, i.e. the Web service-based features within a portal, are usually composed of complex sequences of user interaction and service communication, aggravating the need for an efficient integration solution.
more » ... e present an approach for the business process-driven modeling of these scenarios in form of 'user interaction (UI) workflows' as well as a technical framework enabling the model execution within existing portal systems. The integration of Web services in a portal can thus be realized very efficiently by modeling UI workflows and configuring highly generic activity building blocks for dialog construction, service communication and data presentation.

The role of Situations in Situational Judgment Tests: Effects on construct saturation, predictive validity, and applicant perceptions

Philipp Schäpers, Patrick Mussel, Filip Lievens, Cornelius J. König, Jan-Philipp Freudenstein, Stefan Krumm
2019 Journal of Applied Psychology  
Recent theorizing and empirical evidence suggesting that Situational Judgment Tests (SJTs) are more context-independent than previously thought has sparked a debate about the role of situation descriptions in SJTs. To contribute to this debate and add to our understanding of how SJTs work, this article conceptually embeds SJT performance in a situation construal model and examines the effects of situation descriptions on the construct saturation and predictive validity of SJT scores, as well as
more » ... on applicant perceptions. Across two studies (N = 1,092 and 578) and different SJTs, personality and cognitive ability were equally important determinants of SJT performance regardless of whether situation descriptions were presented or omitted. The effects of removing situation descriptions on the criterion-related validity of SJT scores differed depending on the breadth of the criteria. For predicting global job performance criteria (in-role performance and organizational citizenship behavior), SJT validity was not significantly affected, whereas it decreased for predicting more specific criteria (interpersonal adaptability, efficacy for teamwork). Finally, the effects of omitting situation descriptions in SJTs on applicant perceptions were either negligible or small. Implications for SJT theory, research, and design are discussed.

IntroductionPeripheral artery disease (PAD) is the third most prevalent cardiovascular disease worldwide, with smoking and diabetes being the strongest risk factors. The most prominent symptom is leg pain while walking, known as intermittent claudication. To improve mobility, first-line treatment for intermittent claudication is supervised exercise programmes, but these remain largely unavailable and economically impractical, which has led to the development of structured home-based exercise

It is hypothesised that TeGeCoach improves walking impairment and lowers the need of health care resources that are spent on patients with PAD.Methods and analysisThe investigators conduct a prospective, pragmatic randomised controlled clinical trial in a health insurance setting. 1760 patients diagnosed with PAD at Fontaine stage II are randomly assigned to either TeGeCoach or care-as-usual. TeGeCoach consists of telemonitored intermittent walking exercise with medical supervision by a physician and telephone health coaching. Participants allocated to the usual care group receive information leaflets and can access supervised exercise programmes, physical therapy and a variety of programmes for promoting a healthy lifestyle. The primary outcome is patient reported walking ability based on the Walking Impairment Questionnaire. Secondary outcome measures include quality of life, health literacy and health behaviour. Claims data are used to collect total health care costs, healthcare resource use and (severe) adverse events. Outcomes are measured at baseline, 12 and 24 months.Ethics and disseminationEthical approval has been obtained from the Medical Association Hamburg. Findings are disseminated through peer-reviewed journals, reports to the funding body, conference presentations and media press releases. Data from this trial are made available to the public and researchers upon reasonable request.NCT03496948 (www.clinicaltrials.gov), Pre-results.

Web Application Development employing Domain-Specific Languages

Martin Nussbaumer, Patrick Freudenstein, Martin Gaedke
2006
In Web application development projects, the specification of the envisioned solution is a timeconsuming task suffering from communication problems between the developers and the business. Based on our experiences gained in several real-world projects, we propose an approach combining Domain-Specific Languages and a supporting technical platform. Web application development can thus be performed by composing building blocks and configuring them with DSL programs.
