**6.2 Processing and data analysis**

Some of the main analysis methods that are needed in order to build the evaluation model are: 1) regression-correlation analysis and multi-variate analysis, 2) continuity analysis using Multi-Dimensional Scaling (MDS), 3) Interpretative Structural Modeling to select key parameters in order to determine the SQI, LQI and EQI, 4) Analytical Hierarchy Process to weight each key parameter in determining the SQI, LQI and EQI, 5) SWOT analysis (Strength, Weaknesses, Opportunity and Threat) to strengthen the formulation of management improvement strategies to achieve OPPS.
