Research has shown planning is a central component of goal achievement. Recently the importance of the planning process in entrepreneurship has been brought to light, with literature suggesting that the extent of pre-launch planning may, in fact, contribute to the success of a new venture. While this sort of planning has been acknowledged as important, overall there have been relatively few empirical studies that have looked at planning within an entrepreneurial context, and the field lacks an understanding of factors that contribute to the process of entrepreneurial planning prior to venture launch. Though recent work has examined the context, benefits, and timing of planning for new ventures, there is insufficient knowledge of the factors contributing to planning that are internal to the entrepreneur. We expand the literature by examining internal variables that have not been previously considered.
