To cultivate technology management talents for industry, higher education institutions have developed technology management education since the 1990s. The purpose of introducing technology management course into non-technology discipline, especially Business School, aims to help enterprises foster talents to make appropriate technology-related decisions. This work addresses students' conception performance of learning technology management. This research employs a modified Importance-Performance Analysis method to analyze the course contents' understandability before and after learning by a questionnaire survey. As the results show, the mean scores of almost all themes before learning are below average and median. However, after class, the scores show minor deviation and notable progress, almost twice the scores before learning. That is to say; a scenario-based learning factory approach is effective for the non-technology students to learn technology management knowledge. Besides, there are two teaching themes with low prior knowledge creating major performance and nine teaching units with little prior knowledge creating less improvement. The teaching effort should be addressed in these nine teaching units to improve learning performance in technology management.
