The main objective of this paper was to analyse the performance and efficiency development of the Slovakia's spa sector over the years 2013-2017 by applying the selected modern methods of business performance evaluation-the Economic Value Added, the Return On Net Assets, the Creditworthy Model, the Simplex Linear Programming Method and examine whether the application of these modern models provides an identical view of the financial performance of the sector surveyed. The intention of the paper was also to reveal statistically significant interconnections between the key EVA indicator and other modern methods. In the case of confirmation of a strong correlation we focused on evaluation the degree of identity with the results of above-mentioned applied methods. Despite the fact that these models evaluate performance on the basis of different input data and indicators, year 2015 was identically identified as the best-performing one, vice-versa, the worst financial performance of enterprises was recorded in 2016 within the application of all methods. At the significance level of p < 0.05, a statistically significant correlation between all pairs of the analysed methods was revealed. However, the strongest positive correlation with the Economic Value Added was confirmed in the case of Simplex Method of Linear Programming (= 0.536842). This result was also confirmed by the identical assessment of the performance and efficiency development in individual years. Results of the study pointed to close interconnection between the dimension of performance (the EVA indicator) and efficiency (the Simplex Method of Linear Programming), which will be integrated into a new designed Enterprise Performance Model (EPM).
