SMEs play an important role in the national economy and are crucial to boosting economic performance SMEs in Thailand are also primary business organisms that could help enhance and sustain the wealth of the economy. Nandan (2010) stated that SMEs tend to have independent ownership where owners/managers keep close control as the principal decision makers and provide the majority of the capital required for operations. In many ways, the entrepreneur or owner/manager is the organization and seems to be a part of every business action. Thus, the competence, characteristics, attitude and motives of the entrepreneur have a significant impact on the success of the firm . For survival and success of SMEs, owner/managers should develop knowledge and competence based on his/her comprehension of the job (Sandberg & Targama 1998; Bjurklo 2006).
