Start-ups are an attractive topic for research because they are a relatively new and very dynamic business form. They carry out original business ideas, provide a space for self-realization of independent personalities, bring extra earnings, but most of them fail. The aim of the research was to examine whether the business model and start-up team like two basic assumptions are really some reasons of the viability and later potential start-up success. The result of the research is a knowledge on the structure and functionality of the start-up business model and start-up team. The viability of the start-up had been measured in shape of its business performance. An intensity and structure of the relationships between performance of start-up and its business model and team should confirm its capability to survive and thrive. These relationships are modelled on the base of regression analysis. The research has largely confirmed the existence of desired relationships to a certain extent, but the effect of the studied preconditions is internally considerably differentiated.

New product development (NPD) has gained more attention in innovation literature. Due to NPD may determine the unique position that organizations may conquer. However, few studies have examined how salespeople decide to sell existing products and new products. This importance relies on the premise that new products need to be sold by organization's salesforce. The objectives of this study is to (1) to develop a comprehensive and integrative conceptual framework of the antecedents of salesperson existing and new product selling based on the job demands-resources (JD-R). Based on an extensive literature review and the proposed conceptual framework, a self-administered survey will be develop and will be sent to more than 400 salespeople in high-tech's organizations in Taiwan. Then, SPSS and partial least squares (PLS) will be employed to provide a descriptive analysis of the collected data and for further hypotheses testing. Finally, the study will show the expected findings and expected implications for the current literature and for practitioners.
