Abstract
In recent years, “overshooting," which means product over quality and over performance which result in decreasing profitability, has become a critical issue for firms. Although there are many theoretical studies and case studies related to overshooting, there are a few quantitative analysis. This study picked up mirrorless interchangeable-lens camera. We analyzed the date of product performance and also compared the appearance frequency of terms related to product performance between each product's press-releases and consumers' reviews on a website. Through these analyses, we could discuss overshooting quantitatively and provide new insight for overshooting.
