Abstract: This paper has identified organisational factors and resources that contribute to low productivity and poor quality in caravan manufacturing. Eight productivity-enhancing factors directly linked to caravan manufacturing process were identified and a framework to enhance productivity of caravan manufacturing was proposed. The dataset utilised in this research was obtained from a qualitative data gathering process premised on system observation. The supplier input process output customer (SIPOC) and value stream mapping (VSM) were both utilised to assess the current 'as-is' productivity level of the case-study system. The same tools were deployed for identification of waste generating processes in the system, conduct of analysis for reduction of work in progress inventory and lead times associated with non-value adding activities. The analysis conducted herein was carried out through content and comparative analysis methods using MS Excel 2013 software while the causes and effect matrix was used for data measurement on a prescribed rating scale.
