The research conducted in this study is aimed at enhancing warehouse performance in picking by sequence optimization, as the travel time covers most part of picking processes in storages, a right order of picking lines in a batch is critical to attain high productivity. For a research at the manufacturer in the electronic devices business segment, the quantitative assessment showed an overall improvement potential of 7.4%, but in disparity to systematically working enquiring for routing, the sequences generated by the LSO may look illogical to the picker - a qualitative evaluation must be considered to identify sequence patterns and to discuss the methodology with the picking Personnel. Consequently, the measurements of warehouse performance have become a buzz word amongst scholars and industry practitioners. Despite the fact that, the concept of warehouse performance is attending higher level of significance in western countries, America, Asia, due to its ability of smoothing the business environment, in Africa, particularly in South Africa the integration and adoption of warehouse performance concept is facing several challenges. To date, over the past decade a number of research have been done in the past decades to address these issues of warehouse performance in manufacturing sector and there is still gab in the current literature review, therefore the objective of this research is to review and assess storage performance in manufacturing industry. The results of critical analysis of the current literature clearly show that there are flaws in the current body language related to storage performance. However very few studies have been conducted from warehouse performance in South Africa, the overall of this study is to fill this gab by means of critically analyzing studies that were developed or conducted in the field of warehousing.
