Abstract
In the high school commercial department, we have developed products in cooperation with local companies in classes such as “Product Development and Distribution”, “Comprehensive Practice” and “Issue Research”. However, it is difficult to say that it leads to sustainable product development because product development is often transient, such as ending with sales practice in the school year. In recent years, not only the commercial department, but also the general department, other specialized high schools and junior high schools are practicing product development by utilizing “comprehensive exploration time”, etc., but there is a similar trend. In this article, we will make a case report on the practice of the Okayama Prefectural Kurashiki Washu High School Business Department with the aim of sustainable product development practical training
