Four factors of happiness as design parameters of a product/service

This chapter describes factor analysis results of mental/psychological factors of happiness. We conducted a 29-item, 87-question Internet survey on psychological traits of happiness on 1500 people and performed factor analysis on the results. As a result, we obtained 4 factors: Factor 1 “let’s try it!" (self-realization and growth), factor 2 “thank you!" (connection and gratitude), factor 3 “it will turn out all right!" (positive and optimistic), factor 4 “be yourself” (independence and “my pace”). If we use these as design parameters for products and services, we think that we can develop products and services that can make people happy.
