Correlating a User Experience System to Product Success

Abstract

After reviewing many products from a systems thinking perspective, a pattern has emerged in which successful products seem to more holistically address non-functional requirements (NFRs) that emphasize a user experience (UX) system. To validate this hypothesis, key NFRs – which are believed to contribute to the UX – have been identified, and pairwise comparisons will need to be made between test and control products. To determine whether there is correlation between a UX system and success, a Spearman correlation will need to be performed in which the UX system score for each product is informed by surveys while the success of each product is informed by objective metrics. This paper will demonstrate one subjective analysis of the independent variable and an objective analysis of the dependent variable for one pairwise comparison. Additionally, to demonstrate the mechanics of the Spearman correlation, the results of a second pairwise comparison will be included; however, its analysis will not. Thereby, identifying the complete set of test and control comparisons and investigating whether UX systems – which holistically incorporate NFRs – and success are correlated will be the emphasis of future research and is beyond the scope of this paper.
