Figure 4
A scatter plot titled 'Importance-performance map' displays the relationship between importance and performance of various items. The x-axis represents importance with total effects ranging from 0.013 to 0.203, while the y-axis represents performance ranging from 0 to 100. The plot includes several data points, each represented by different shapes and colors, indicating various items. Clusters of data points are visible around the 0.03 to 0.05 importance range and 60 to 80 performance range. Some outliers are present, particularly at higher importance values. The data points are color-coded and shaped differently to represent different items. All values are approximated.Importance-performance map analysis at item level. Source: Authors’ own creation
