Management of product design projects becomes increasingly difficult as the complexity of products increases. For better management of such projects, well-considered preliminary coordination of design processes is essential. This paper proposes a method for coordination in the design process, which comprises two phases: 1) division of the design work into smaller tasks and sequencing them and 2) establishment of management activities. To facilitate this coordination, an integrated model of a product, process, and organization is proposed. The division and sequencing of design tasks is based upon analysis of the product model. The method utilizes rational prioritization of design parameters, which means identification of parameters that must be first considered for changes. The resulting design processes can show where coordination among design tasks is needed. This, in turn, implies the necessity of management. It is preferable for a different style of management to be adopted for each part. Here, the importance of management and organizational structure prescribe the style of management that should be adopted. In this paper, two approaches to management are discussed: 1) the formation of a pre-agreement, and 2) integration and after-approval. Throughout the paper, the example of a solar boat design is used to explain how the proposed method works and to demonstrate its feasibility.

Interfaces and prostheses, whether physical, visual, or virtual, are more and more characterized by an ever-increasing level of complexity. In this designing scenario, the relationship with cognitive sciences, ergonomics, semiotics, and the contribution of enabling technologies is transforming the field of product design into that of the design of complex systems that interface the relationship between human and machine.

Environmental effects are not considered sufficiently in product design. Reliability problems caused by environmental effects are very prominent. This paper proposes a method to apply ontology approach in product design. During product reliability design and analysis, environmental effects knowledge reusing is achieved. First, the relationship of environmental effects and product reliability is analyzed. Then environmental effects ontology to describe environmental effects domain knowledge is designed. Related concepts of environmental effects are formally defined by using the ontology approach. This model can be applied to arrange environmental effects knowledge in different environments. Finally, rubber seals used in the subhumid acid rain environment are taken as an example to illustrate ontological model application on reliability design and analysis.

Abstract Refinement of product design processes is recognized as a means for organizations to impact lead times, cost, and quality. Although methods such as the design structure matrix (DSM) exist to analyze design processes, their applications have been limited by overhead in collecting data and maintaining accurate representations. Representation timeliness and resolution issues have typically led to static, high-level process views. In this work, the design process is derived dynamically from an evolving network of design resources inter-related by service dependencies. This network is created to simulate the state of a product design. Through the analysis of resulting dependencies, high-resolution networks of task and parameter interdependency can be extracted. A software module is developed to provide the service of automatically extracting and analyzing the structure of service exchanges in integrated design models. The module provides a matrix or DSM visualization of service relationships and mechanisms to sort resources according to service priority. This allows for realtime evaluation of design processes as models of the product evolve, providing information to guide the strategic addition of resources.

Automated content analysis software tools have significantly aided in the study of design processes in the recent past. However, they suffer from the lack of domain knowledge and insight that a human expert can provide. In this paper, we adopt the use of text visualization techniques that help in gaining insights and identifying relevant patterns from the results obtained through a content analysis software. We motivate our approach with the observation that examining overall patterns in data aids us significantly in identifying interesting and relevant details concerning specific contexts in the data. We use the proposed approach to study the effect of adopting Laseau’s “design funnel” of alternating divergent and convergent design processes among student teams in a toy design course, and compare it to student teams that follow a free brainstorming process. We demonstrate the application of lexical dispersion plots and text concordances as a means to further examine the output of a conventional content analysis tool, and use these techniques to separate patterns from anomalies. We identify cases of concept consistency across teams using the dispersion plots, and identify cases of multiple word senses through text concordances. Finally, we present insights that were obtained through these visualizations and propose contexts for further studies of the data.
