Abstract
The footwear industry is one of the most economic sectors, which should be given attention for the development of the Ethiopian country and Ethiopian Leather development strategy has put the footwear industry on the forefront position to accelerate the development of the sector with a huge potential for boosting the country economy and it needs consideration. Ethiopian Footwear Industry sector needs improvements to enhance their productivity and the study focused on the ASSC as a case study and the currently ASSC target plan production per day averagely of cutting, stitching, and lasting and finishing section are 750, 700, and 700 pairs per day respectively of Gentles man’s and civilian shoes (EL-028102LB model), but the actual output is 563, 427 and 463 pairs of actual finished shoe output performance of 66% with a line efficiency 61.1%, 50.5%, 52.89% and daily labour productivity of each section is 22.5, 8.1, and 8.9 pairs per day respectively. The existed gap between the target plan and actual output is because of the existed major factors of distance and movement time, high cycle time, bottleneck, less line efficiency, less output per day, and less labour productivity. Then, the study focused on and reduce factors that affect the productivity and enhance the productivity of the ASSC through work measurement and line balance techniques. After apply full of the work measurement and line balance on the ASSC, the result of the study is reduced total of unwanted movement distance with a time, cycle time, number of operations (station), and the labour from the existed are 34m with 136 second per pairs, 498.19second, 8 number operations, and 9 labour and increased line efficiency of the cutting, stitching and lasting, and finishing section to 80.76%, 76.8%, and 75.50% and output per day in pair are 714, 625.3 and 623 with the increased labour productivity per day in pair to 34, 12.3 and 12.7 respectively. Generally, ASSC enhanced productivity of finished footwear output is 623 pairs per day with an additional produced of 160 pairs of shoes per day and the actual finished shoe output performance of the company is increased by 23%.
