In the past Davidsson (1995) put in great effort to compose the previous work and models and his greatest contribution was the addition of the variable of convictions as a prediction of entrepreneurship and entrepreneurial action. Also he contributed to the examination of the personal profile of an individual in his attitudes towards entrepreneurship, of which he differentiates in general and attitudes towards the subject.
During that same period, Krueger and Brazeal (1994), apart from what the model of Entrepreneurial Event supports, imported the variables of reliability of an individual an the dynamic potential that he develops for entrepreneurship. This work formed the foundation for the further development of the model by Krueger (2005) since he introduced the individual desire and social norms as defining variables of perceived desirability and self-efficacy and collective efficacy as defining variables of perceived feasibility. It must be noted that this model is one of the first that specializes more on a second level predicting variables of entrepreneurial intentions.
By examining the importance of affective and rational factors of the environment that influence the individual Grundsten (2004), in the model, distinguished the importance that social norms have on perceived desirability, but also the technological environment and economic expectations in perceived feasibility. As it is easy to conceive, the researcher dealt only with external factors and not with the characteristics of the personality of the individual, restricting the extent of the predicting model.
Linan (2005), who on one hand supports personal convictions as a predicting variable of perceived desirability and on the other hand supports that entrepreneurial knowledge may contribute positively to entrepreneurial intentions, used a more holistic approach.
As it can be realised from the above, the development of the concept of entrepreneurial intentions, despite the fact that it has been examined for many decades, is still in an initial stage. We could summarize the evolutionary course concisely in table 1 below, which presents the time sequence of research in the field.

From the above analysis of the evolution of the concept of entrepreneurial intentions, it emerges that both perceived desirability and perceived feasibility constitute variables that predict intentions according to most researchers and for the past years overwhelming effort is being placed to develop the models that predict these variables penetrating in greater depth in the analysis of entrepreneurial intentions. We could briefly present in the following graph 1 the synthesis of the predicting models that have been supported to date on entrepreneurial intentions.
