The research examines the criteria that should be considered to pose an interactive application in relation to the needs of the engineer-designer-user in the "small and medium enterprises" background. It also appears the need to consider the possibility of creating interactive applications which let perform diffferent installation projects. The general hypothesis starting point is the use of interactive applications as a standard tool in small and medium enterprises working in engineering facilities, improving business productivity, reducing errors and improving project acquisition and knowledge management users. Considering the areas, the purposes and the goals of this research, it responds to the problematic aspects of the installation projects and the problems that need to be solved in the interactive applications. It also responds to the possibility of generating interactive applications that meet the needs of small and medium enterprises in the engineering environment and also creats interactive applications wich help to control over the installations projects. The needs assessment of small and medium enterprises in the project engineering area has been perfomed by using empirical data adquired by analyzing the characteristics of the investigated companies, their capability on creating its known-how, the way of how they implement their methodology in the project performing and their information, learning and development projects needs. In the setting of this research theoretical proposals are reviewed relating the project implementation rules and it is also analyzed the standards and norms that affect the activity projects and the installation projects. It's also discussed the administrative procedures of enginnering project processing record. Finally, the thesis explores in the influence of technological innovation in the business environment, on the way that affects the organizational structure, and points out the influences the new competitive dynamics in the in the new information society
