Product development is performed by proficient designers, who make their best effort to understand customer needs and desires via verbal or written interview. This approach becomes cumbersome if a product design undergoes revolutionary changes. In this paper, potential of real-time simulation models based on Multibody System Dynamics are utilized as a tool to interpret customers' needs. The complete real-time simulation model can be considered as interaction of several subsystems which are environment, work process, mechanics, actuators, control system and user input. A mechanical subsystem based on the use of multibody system dynamics includes modeling of mechanical bodies, force elements acting between bodies, joints connecting bodies, and contacts. In this way, three main area of applications are introduced consistently. Firstly, benefits of the process is discussed in Research and Development and Product Development domain. Latter comes R&D service business part and eventually authors investigate effect of the approach in marketing and sales.

Digital tools have become indispensable for the testing and modification of prototypes in mobile and industrial machine manufacturing. Data that are extracted from virtual experimentation and analysis are both affordable and valuable, due to their repeatability and because they are close to real-world observations. Expert knowledge is a prerequisite for full deployment of computer aided engineering tools in the design phase and concomitant stages of product development. Currently, such knowledge, for the most part, is provided by the product development team and the manufacturer. Yet, it is important that manufacturers and designers receive end-user feedback throughout the product development process. However, end-users often lack sufficient know-how about the technical and engineering background of the product development, and this lack of understanding can become a barrier to user-designer communication. The aim of this article is to present an alternative to traditional design approaches that is based on customized real-time multibody simulation. This simulation-based approach can be seen as a platform that has the potential to improve knowledge management systems for product development. End-user feedback to the designer is given in a systematic manner throughout the design process using a multipurpose XML-based multibody environment.
