This paper presents a comparison of design methodologies and process models from nine disciplines. The evolutionary development of the approaches, which can be traced back to similar roots, lead to process models which are now adapted to specific design disciplines but still have many similarities. Most of the established approaches have not been adapted to many of the challenges of current design practice and represent isolated views on the design process. This comparison is intended to provide a basis for consolidation and reformation of design methodology. [less ▲]

The presented research aims at contributing to a better understanding of the diverse functional modelling approaches proposed across disciplines, often involving more than one function model. The paper presents a review of 41 systematic design approaches from different disciplines, analysing what is addressed by functional modelling at which point in the proposed development process, i.e. in which sequence, if any. The analysis aims at deriving potential commonalities across disciplines, which could support the development of an integrative functional modelling approach. Finally, the results of the analysis are discussed, concluding that while there seems to be no shared sequence in functional modelling across disciplines, a common base can be derived, with regard to what is prominently addressed by functional modelling in the different disciplines.

The research presented in this paper discusses the different understandings of function which hamper shared functional modelling. Function models proposed in literature from various disciplines are then analysed, in order to identify the different inherent functional modelling perspectives. The paper concludes that in order to support shared functional modelling and to support cross-disciplinary system development, these different functional modelling perspectives need to be linked.

Design models are an important means for the representation of design information in product development processes. Designers use design models to visualise and communicate their ideas to other members of a design team, the project manager or a costumer. Communication between experts from different disciplines using design models is often hindered by different terminology and different ways of modelling. Potential consequences are design flaws, which may lead to time-consuming iterations and – if undetected – to problems during production or use. In order to enhance the communication through design models across disciplines, and to address the mentioned problems, an understanding of similarities as well as differences between modelling approaches needs to be established. For that purpose, this paper discusses different design states which represent a distinct level of available information in the development process. They are derived through comparing different design models proposed in literature and provide the basis of a framework for a detailed comparison of modelling approaches across disciplines. Further, first insights into different ways of modelling are discussed. [less ▲]

Design models are an essential means for abstract representation and visualisation of information in the design process. Comprehension of design models in interdisciplinary engineering design teams is often hindered by different terminology and different discipline-specific modelling approaches. This paper presents the results of an interview study conducted with practitioners and researchers from engineering design and building design. The study elaborates the different ways of collaboration and use of design models in building design as compared to engineering design, in order to derive the potentials for cross-fertilisation between both areas of product development.

Challenges resulting from an environment characterised by complexity, competition on global markets, dynamics and ever-changing user wants and needs are increasing and affect all design processes, irrespective of whether the product or system designed is a machine, a building, software, service, etc.. These challenges require collaboration between disciplines, but current design processes of large systems, such as aircraft, essentially show separate development strands for each discipline. Research into methods is ongoing, but the original design methodologies have not been adapted accordingly. Based on a literature study this paper consolidates findings from different comparisons of design methodologies and process models across disciplines. A consensus can be found that at least on an abstract level design process models have a generic core of common stages. On a detailed level the picture is different. The extent to which design approaches appear similar depends on the perspective of the analyses. The literature study provides an overview of shortcomings of existing design methodologies which may serve as starting points for further research and development of design methodologies. [less ▲]

Die Konstruktionsforschung strebt danach die Entwicklungspraxis zu unterstützen indem Methodiken, Methoden, Tools und Empfehlungen erarbeitet werden, welche die Arbeit der Entwickler erleichtern sollen, mit dem Ziel bessere Produkte zu entwickeln. Das Umfeld der Entwicklungspraxis ist dabei gekennzeichnet durch Komplexität, Wettbewerb auf globalen Märkten, Dynamik und sich ständig ändernden Kundenwünschen und -bedürfnissen. Die daraus erwachsenden Herausforderungen nehmen fortlaufend zu und tangieren alle Entwicklungsprozesse unabhängig davon ob eine Maschine, eine Software, ein Service oder ein andere Produktform entwickelt wird. Neben den genannten Aspekten stellt auch das veränderte Konsumentenverhalten eine Herausforderung für die Produktentwicklung dar. Das Internet ermöglicht eine nie dagewesene Auswahl- und Vergleichsmöglichkeit von Produkten, wodurch wesentlich selektiver konsumiert wird und infolge dessen Produkte immer differenzierter und tärker an die Kundenwünsche und –bedürfnisse angepasst werden müssen. Abhängig von Entwicklungsgegenstand, Marktsegment, Branche und weiteren Faktoren sind die existierenden methodischen Hilfsmittel unterschiedlich gut geeignet, die Arbeit des Entwicklers zu erleichtern und die Entwicklung besserer Produkte zu unterstützen. Dies bedeutet, dass methodische Ansätze Kontext-abhängig ausgewählt bzw. adaptiert werden müssen. In jüngster Zeit hält Design Thinking, ein neuer Ansatz zur methodischen Produktentwicklung, Einzug in verschiedenste Branchen. Im nachfolgenden Artikel wird Design Thinking kurz beschrieben und exemplarisch mit dem methodischen Vorgehen nach Pahl und Beitz verglichen. Der Vergleich beinhaltet den Prozessumfang (welche Phasen des Entwicklungsprozesses werden abgebildet) und ausgewählte Kontext-Aspekte (für welche Art von Entwicklungsvorhaben ist der Ansatz anwendbar). Anhand dieser Aspekte wird diskutiert, welche wesentlichen Unterschiede zwischen den Ansätzen bestehen, wo Überschneidungen existieren und welches Potential die Kombination beider Ansätze in sich birgt.

Estimation in its diverse forms is assumed to be relevant for problem solving in engineering design due to the inherent deficiencies in information availability and reliability. Nevertheless aside from some exception estimation as a method is hardly mentioned in standard literature on systematic approaches to engineering design like Pahl and Beitz. As well it is rarely deliberate addressed in engineering education. Engineering designers are expected to gain estimation competence by experience. Good performance in estimation and the development of estimation competence by hat is left to chance. Estimation as a problem solving strategy covers a wide range of activities on a continuous spectrum between the extremes of random guesses and highly mathematical statistics based approaches. Our research addresses estimation activities which are solely based on cognitive performance, without using specific mathematical procedures or technological support. Our current study is an explorative, qualitative protocol analysis of two idea creation meetings addressing different problems in the early phases of a technology-driven innovation project recorded by the DTRS7 organisation. The addressed research questions are: Where, how, why and what for is estimation used in engineering design? This analysis should give further insight in the not widely delineated topic of estimation in engineering design. [less ▲]

Product development projects are difficult to plan due to complexity, dynamics, lack of transparency and polytely. Risk Management is often used to cope with this situation. Linkography is adapted with the aim to ease the effort of the Risk Management process. Linkography is used to focus all Risk Management activities on those work packages which might affect the project the most in the case of failing the expected outcome. The criticality of a work package is defined by the number of links to other work packages, its duration and its costs. By applying Linkography as a Risk Management method, a prioritized list of work packages can be generated which pass consecutively through the usual Risk Management process. Unlike other methods, Linkography supports the user in a visual manner. Hence, Linkography can easily be used for communication with unskilled stakeholders. [less ▲]

This paper presents the results of an explorative, comparative protocol analysis of two design meetings that focused on identifying how the style of the Design Task Description influences the course and the outcome of an idea generation meeting. A framework is used to allocate potential influencing factors, including the DTD, and to discuss the various relationships and influences in order to understand the differences in course and outcome of the meetings. The style of the DTD was found to influence the length of the analysis phase and lead to differences in the course of the two idea generation meetings and to a higher idea generation rate. [less ▲]

Project Risk Management is used to prevent projects to fail. Despite its proven use, barriers still exist that hinder implementation and use by inexperienced persons. One barrier is the additional effort required by the process of Project Risk Management itself. An additional barrier is the lack of systematic support of important steps like the selection of an appropriate risk treatment strategy. The decision which strategy to select is a challenging task due to the uncertain character of the addressed issue. The trade-off of the perceived additional efforts caused by a method must be addressed by an enhancement of the cost-benefit ratio of the applied methods and implemented risk treatment measures. Decision making using the proposed Measure and Failure Cost Analysis (MFCA) method enables the Risk Manager to compare the arising costs of different risk treatment strategies caused by an occurring risk and risk treatment measures. It is based on a de-escalation principle which analyzes the course of the impact of an event. The method compares the reaction rate of different strategies and proposes the favorite one. [less ▲]

Estimation is assumed to be a relevant method for problem solving in product development due to the deficiencies in information availability and certainty, as well because of short resources. Nevertheless estimation as a method is hardly mentioned in literature on product development nor is it part of engineering education. As a consequence good performance in estimation and the development of estimation competence is left to chance, i.e. expected to be built up through experience. We believe that estimation can be supported and taught. Hence estimation competence can be developed purposive and more quickly. The aims of the research introduced in this paper are to understand relevance and functioning of estimation in engineering design, and to develop support for engineering practice and education based on this understanding. This paper focuses on demonstrating the topics’ relevance by addressing the following questions: •Why is estimation important for engineering design? •What is the state of the art in understanding estimation in general? •What is the state of the art of estimation as a method in engineering design? On the basis of this initial investigation we propose our research framework. After goal, approach and scope of our research, the main research questions on estimation in engineering design we wish to answer are formulated, and the research methods we are using. Furthermore first results on characteristics of estimation in engineering design identified by tests, as well as video and protocol analysis are summarized. At least an outlook on the prospect research is given. [less ▲]

In order to remain competitive, e.g. in the face of globalisation, many small and medium-sized product development manufacturers feel the need to change or refine their development processes. One of the key activities is to systematically translate the needs of customers into development requirements. Little is known about how small and medium enterprises (SMEs) deal with the complex topic requirements management and studies of large numbers of cases are still the exception. Many SMEs have problems in managing requirements. They often have the capabilities for requirements management but the processes are not well defined, e.g. insufficient monitoring of specifications and poorly organised customer contacts. How to work with frozen specifications and how to handle the wishes of the customers seem not to be fully understood. This paper presents selected results of an empirical study into product development of SMEs in the UK. The predominantly qualitative data was collected using a questionnaire which was designed as a self-help package. [less ▲]

Zur Darstellung des theoretischen Rahmens dieser Arbeit werden ein Modell zur Visualisierung der Vernetzung von Einflussfaktoren auf den Projekterfolg aus den Domänen Projekt-Management, Produkt und Stakeholder und ein Verbesserungsprozess zur Steigerung der Robustheit von Produktentwicklungsprojekten vorgestellt. Vor diesem Hintergrund werden die Grenzen aber auch die Möglichkeiten generischer Lösungsansätze diskutiert. Anhand einer Fallstudie wird untersucht welche Barrieren die Durchführung des Verbesserungsprozesses und somit auch die Anwendung der Lösungsansätze in der Praxis erschweren. Die Analysen zeigen, dass die Kenntnis der Ursachen von Problemen, die zu Planungsabweichungen in Produktenwicklungsprojekten führen, und eine entsprechende Anpassung der Handlungsempfehlungen Voraussetzungen zur Implementierung daraus abgeleiteter Maßnahmen sind. Die domänenübergreifende Betrachtung möglicher Einflussfaktoren gemäß dem Konzept der Robustheit führt während der Ursachenanalyse zu einem fundierten Verständnis der Problemlage und ermöglicht eine bessere Anpassung der Lösungsansätze. Aus den theoretischen Vorüberlegungen und den Ergebnissen der Fallstudie werden Anforderungen an die Weiterentwicklung des Ansatzes zur Steigerung der Robustheit von Produktentwicklungsprojekten abgeleitet, der die Anwender unterstützen soll, den Transfer empirischer Erkenntnisse und Handlungsempfehlungen auf individuelle Problemstellungen zu vollziehen.
