THE VALUE OF CUSTOMER SERVICE AS A FUNDAMENTAL DIMENSION OF THE BUSINESS MODEL OF COMPANIES IN THE TFL SECTOR, FOCUSED ON SALES REVENUE

This article aims to examine the relationship between the fundamental dimension of the business model and the amount of sales revenue. The study was conducted using data from the TFL sector companies. The research task was performed with the use of statistical methods. In order to identify services significantly differentiating the revenues of companies from the researched sector, non-parametric Mann- Whitney test was used. The article also makes an attempt on predicting, with the use of regression trees, the amount of sales revenues, depending on the type of the offered service. The study allowed for the adoption of a revised research hypothesis stating that a properly selected set of services in the business model translates into higher revenues from the sale of the businesses from the TFL sector.
