This study is part of a larger research study that seeks to understand how employee-driven innovation (EDI) is initiated, enacted and sustained in small and medium enterprises (SMEs) in Singapore. To date, most of the EDI studies are conducted in the Nordic context where management, employees and public authorities work closely with each other. In more hierarchical societies, such as those in Asia, employees may be given less discretion in exercising initiative to improve work processes and conditions. This study seeks to provide insights on factors that support employees initiating, enacting and sustaining innovations in Singapore SMEs through case studies. Besides interviews, data gathering was also undertaken through observations of the employees, supervisors/managers and owners at work and their interactions where possible. It is found that employees' engagement in workplace learning contribute to initiation, enactment and sustenance of EDI in Singapore SMEs. The findings underline the significance of workplace learning in developing and strengthening employees' innovation capacity.
