Previously, production management in small and medium enterprises (SMEs) relied on traditional, paper-based check sheets, which were labor-intensive and prone to error. This research was conducted to develop the Cost-Effective IoT Control System for Digital Check Sheet as a solution to improve production management among Malaysian manufacturing sector SMEs in the Industrial Revolution 4.0 era. The integration of the CEICS involves AppSheet for mobile applications, Google Sheets as a database platform, and Looker Studio as a business intelligence tool in visualizing the implementation results. CEICS replaces the traditional manual documentation processes with a digitalized process, real-time tracking, and registration of the item record structure. It also provides an intuitive dashboard and mobile app for real-time monitoring, having much higher productivity and accuracy of data. The system was implemented and tested with the help of an Malaysian SME. The results comprise reduced manual data errors, smoother and faster procedures at work, and efficiency in management. This solution is practical, scalable, and can enable SMEs to achieve Industry 4.0 standards in meaningful, desperately needed affordable digital transformation; this will be achieved with the power of automation driven by IoT to advance operational effectiveness in the competitive manufacturing landscape.
