The findings of this study show that (1) using the RST, the behavioral indicator “Weighs the value of each elements of a problem” can be used to reliably identify a small firm entrepreneur, while the behavioral indicator “Knows the different urgency of elements of a problem” or “Makes feasible solutions for actions” can be used to identify a large firm manager; (2) using the BAV, the behavioral indicator “Builds a mechanism for talent development” can definitively distinguish a small firm entrepreneur from a large firm manager; (3) the competency “Analytical Thinking” from the RST and the competency “Developing Others” from the BAV, are the key competencies which may be used to determine whether a given individual is an “Entrepreneur” or not; and (4) by using either the RST or the BAV, we can effectively differentiate whether a given subject is an “Entrepreneur” or not, with reference to a very minimal number of attribute-values (behavioral indicators).
