“…According Fuh and Li (2004), digital representations are product descriptions in technical design language, created by Computer-Aided Design (CAD) tools. These computational tools are used in New Product Development and project optimization and aim to assist users in specification, modeling, visualization, and simulation of products.…”

The product innovation management literature indicates vision as vital for product development success, especially for the innovative ones. Scholars have recently brought this idea to the center stage due to the Agile Project Management and Innovation literature and suggested that it should be managed. However, there is a lack of operational definitions for product vision and the conception of product vision management. It is a theoretical problem and a barrier for professionals interested in putting this idea in practice. This study contributes with a definition of product vision, the conceptualization of product vision management and a systematic analysis of available product representation models, identifying their advantages and disadvantages, for product vision support. These results were found through a systematic analysis of models used in New Product Development Management and Agile Project Management literature. It examines models of functions, digital representation, product structure, and requirements. It proposes that a body of knowledge on product vision management is a key element to support innovative product development projects. The paper offers a starting point for the development of methods and models capable of solving the problem for both Agile Project Management and New Product development scholars.

“…In both cases, one of the most important issues to consider is the likely data loss that would occur as a result of migrating the data to the new format. To take a simple example from common formats, there are a number of options for migrating complex word processor documents, besides converting to similar binary formats: Rich Text Format is ASCII-based and can express most aspects of a Microsoft Word document, notably excepting VBA scripting, Word user interface customization, document versions and some metadata fields [64]; simple HTML + CSS can express most of the structure and formatting of a document; 3 while plain text expresses only the textual content without any formatting. Depending on the circumstances, some data loss may be desirable and some may be unacceptable.…”

Long-term users of engineering product data are hampered by the ephemeral nature of CAD file formats and the applications that work with them. STEP, the Standard for the Exchange of Product Model Data (ISO 10303), promises to help with meeting this challenge, but is not without problems of its own. We present a complementary solution based on the use of lightweight file formats to preserve specific aspects of the product data, in conjunction with a registry of relevant representation information as defined by the Open Archival Information System Reference Model (ISO 14721). This registry is used to identify suitable destination file formats for different purposes, and provides a resource to aid in the recovery of information from these formats in the future.

“…However, it has not been used to any great extent as an instrument of communication. In other domains, most prominently that of computer-aided design [22], it has been used as a communication enhancer for some time, for example to support remote collaboration between geographically dispersed teams [23-25], to review designs over distance [26-28], and to offer training and support to remotely located service personnel [29]. …”

BackgroundMedication misuse results in considerable problems for both patient and society. It is a complex problem with many contributing factors, including timely access to product information.ObjectiveTo investigate the value of 3-dimensional (3D) visualization paired with video conferencing as a tool for pharmaceutical advice over distance in terms of accessibility and ease of use for the advice seeker.MethodsWe created a Web-based communication service called AssistancePlus that allows an advisor to demonstrate the physical handling of a complex pharmaceutical product to an advice seeker with the aid of 3D visualization and audio/video conferencing. AssistancePlus was tested in 2 separate user studies performed in a usability lab, under realistic settings and emulating a real usage situation. In the first study, 10 pharmacy students were assisted by 2 advisors from the Swedish National Co-operation of Pharmacies’ call centre on the use of an asthma inhaler. The student-advisor interview sessions were filmed on video to qualitatively explore their experience of giving and receiving advice with the aid of 3D visualization. In the second study, 3 advisors from the same call centre instructed 23 participants recruited from the general public on the use of 2 products: (1) an insulin injection pen, and (2) a growth hormone injection syringe. First, participants received advice on one product in an audio-recorded telephone call and for the other product in a video-recorded AssistancePlus session (product order balanced). In conjunction with the AssistancePlus session, participants answered a questionnaire regarding accessibility, perceived expressiveness, and general usefulness of 3D visualization for advice-giving over distance compared with the telephone and were given a short interview focusing on their experience of the 3D features.ResultsIn both studies, participants found the AssistancePlus service helpful in providing clear and exact instructions. In the second study, directly comparing AssistancePlus and the telephone, AssistancePlus was judged positively for ease of communication (P = .001), personal contact (P = .001), explanatory power (P < .001), and efficiency (P < .001). Participants in both studies said that they would welcome this type of service as an alternative to the telephone and to face-to-face interaction when a physical meeting is not possible or not convenient. However, although AssistancePlus was considered as easy to use as the telephone, they would choose AssistancePlus over the telephone only when the complexity of the question demanded the higher level of expressiveness it offers. For simpler questions, a simpler service was preferred.Conclusions3D visualization paired with video conferencing can be useful for advice-giving over distance, specifically for issues that require a higher level of communicative expressiveness than the telephone can offer. 3D-supported advice-giving can increase the range of issues that can be handled over distance and thus improve access to product information.
