“…Although past studies have shown that role ambiguity can affect the job performance of employees in the service setting, most of them were conducted abroad, thus very little evidence exists to understand the job performance of employees in the context of Malaysia. Furthermore, most SME researches in Malaysia focused on productivity and skill shortages (Yogeesvaran, 2005;Hamzah & Ho, 1994;Tan, 1996;Saleh & Ndubisi, 2006), entrepreneurial problems (Abdullah, Hamali, Deen, Saban & Abdurahman, 2009), TQM and organizational performances (Sohail & Hoong, 2003), empowerment (Wyer & Mason, 1999), ICT adoption among SMEs (Alam & Ahsan, 2007), SMEs historical development (Hashim, 2000), staff training and SMEs performance (Jamaludin & Hasun, 2007) and assessment criteria of banks towards small business borrowers (Mahmood & Rahman, 2007). Given such a situation, it necessitates this study to be carried out in view of the importance of the service sector SMEs in Malaysia.…”
