Many features can be found similar in nature while studying previously implemented projects, if they are analyzed for capturing their embedded knowledge. These are regarded as the most inherited valuable assets which are usually neglected unintentionally at work. They can be utilized quite successfully for projects to be implemented in future. If this tacit knowledge is revived successfully in a systematic manner, it can be used as a guidance tool while implementing future projects with smaller risk takings. Inability to convey this knowledge to the implementers of the new projects, seems to be a harsh condition at present, which calls for a serious challenge to devise a methodology for capturing and conveying this needy asset. People who move from one place to another always carry experiences and professional ties with themselves , since there are not formal exchanging channels foreseen. Therefore their knowledge should be accessed via informal networks. Documenting systematic errors can unveil hidden traps which can be sources of risk taking conditions and presenting valuable lessons for implementing successful projects. This paper aims at presenting a model for capturing the embedded knowledge of previous projects in the special motor vehicle industry, through a special consideration applied to. It is intended to get hand to the explicit hidden value in the projects. The gaining results of implementation of this model are applied to the Iranian motor vehicle industry to validate its effective applicability for which satisfactory results are found.
