Conference Paper
Full-text available
We are interested in the problem of evaluating and selecting one or more ideas to be pursued in the idea stage of the innovation process. The so-called scoring method, which is based on Multi-Attribute Utility Theory is very commonly used for this task. We know of many corporations that select their innovation projects using this technique. We pres...
Article
Full-text available
The purpose of the research described in this paper is to improve the understanding of the analogy technique for generating ideas, in particular for business applications. There has been very little research done on this topic, and thus hardly any advice is available for innovation managers and marketers, who rely on good ideas to achieve their obj...
Conference Paper
Over several decades, a variety of studies have analysed analogical thinking as a cognitive mechanism, in which the individual transfers information from similar situations or problems and uses it to solve problems. However, less research is given that focuses on the use of predefined analogies as external stimuli for the ideation process. As a res...

Lean Start-up is a management process for start-ups that emphasizes learning via hypothesis formulation and experimentation. The business model is the paradigm of choice for designing the start-up company and for obtaining funding. Although many business model architectures have been suggested, we believe that none is well-suited to the needs of a...
Chapter
The context of complex design and engineering processes is characterized by dynamic requirements, like changing process goals or group constellations. To deal with these dynamics in a virtual environment, a context-sensitive collaboration support system needs to consider a changing context and provide virtual teams with the support they need. Such...

Conference Paper
Full-text available
Dynamic environments characterize today’s world. In complex design and engineering processes, dynamic environments influence the requirements of an ongoing collaboration process. They lead to process goal changes or reduce the time available to achieve a collaborative goal. In such a case, collaboration support and processes need to be adapted. Var...
Conference Paper
Today, engineering systems offer a variety of local and webbased applications to support collaboration by assisting groups in structuring activities, generating and sharing data, and improving group communication. To ensure the quality of collaboration, engineering system design needs to analyze and define possible collaboration processes. Currentl...

Chapter
This chapter gives a comprehensive overview of ongoing research about semantic approaches for Collaboration Engineering. We will present a new ontology-based approach, where each concept of the ontology corresponds to a specific collaboration step or a resource, to collect, manages and share collaboration knowledge. We discuss the utility of the pr...
Conference Paper
Full-text available
Collaboration is an important process for companies to combine the potential and expertise of their employees. Groupware can improve the productivity of collaboration by coordinating activities and improving group communication. Considering the possible complexity of a collaboration process, the faithful appropriation of a groupware technology is f...
Article
In the field of collaboration engineering, thinkLets describe reusable and transferable collaborative activities to reproduce known patterns of collaboration. This paper focuses on thinkLets of the pattern Generate, which define collaboration activities to produce and share new contributions by a group. We address the question whether the small num...
Conference Paper
Full-text available
Idea generation techniques provide a variety of approaches for supporting an innovation process. Until recently, the space of techniques has been unstructured, and no clear guidelines have been available for the selection of an appropriate technique for a given innovation goal. We used the ‘change of perspective’ paradigm as an approach to study id...
Conference Paper
Full-text available
This paper describes a course in innovation offered to students at the University of Magdeburg in Germany. The course is based on the premise that idea generation can be viewed as a methodical discipline, and offers a unique combination of the psychological framework for creative thinking, the business background for innovation and state-of-the-art...

Collaboration is a social and interactive process, where participants join efforts toward a group goal. A Group Support Systems (GSS) can improve the productivity of collaboration work by structuring activities and improving communication. However, knowledge is needed for the faithful appropriation of GSS technology. In this paper we present ongoin...

Collaboration is a social and interactive process, where participants join efforts toward a group goal. A Group Support System (GSS) can improve the productivity of collaborative work by structuring activities and improving communication. By using context-based adaptive techniques, a GSS can support facilitation of the participants by offering appr...

Creativity techniques provide a variety of approaches for supporting an ideation process. These techniques can be executed using a Group Support System (GSS), thus allowing the ideation process to be distributed across geographical distances. However, experience is necessary for the selection of an appropriate creativity technique, its implementati...
Conference Paper
In this paper we present ongoing research about a supporting framework that improves Group Support Systems (GSS) for Collaboration Engineering (CE). CE uses a pattern design approach which allows groups with no design skills, and only limited facilitation skills, to design and execute efficient and effective collaboration processes. Our research tr...
Conference Paper
Full-text available
Group Support Systems (GSS) can improve the productivity of Group Work by offering a variety of tools to assist a virtual group across geographical distances. Experience shows that the value of a GSS depends on how purposefully and skillfully it is used. We present a framework for a universal GSS based on a thinkLet- and thinXel-based Group Process...
Conference Paper
Full-text available
This paper describes a new algorithm for the evaluation of alternatives by a group of decision makers according to multiple criteria. The algorithm is motivated by the need to quickly evaluate a large number of ideas in the early stages of an innovation process, when little or no information about the ideas is available. The algorithm is based on a...

Conference Paper
Full-text available
Computer-supported creativity tools are one example of Group Support Systems (GSS) which have been shown to outperform their traditional face-to-face counterparts. We present a framework for GSS which is based on formal languages and the new concept of a ThinXel. The name "ThinXel" (thinking element) is formed analogously to the wellknown "pixel" (...
