| dc.description.abstract | Ethiopian footwear manufacturing companies have limitations to compete in the global market. This sector is considered to play major role in increasing country’s economy especially in export. But it is not competitive in the international market due to various internal and external factors. This study was a case analysis on the development of an improved model that works to enhance productivity in the selected shoe factory. The procedures include literature survey, data gathering, and interview with the experts and factory observation to assess the existing work flow. The data analysis was done using Pareto analysis, Cause and effect diagram, lean maturity, value stream mapping and an AutoCAD. Lean manufacturing is to remove waste, decrease the lead time, increase the PCE and rise the profit and productivity .This work addresses the implementation of lean tools by selecting a gentle man shoe model known as SAWA Lafric and observed its production activity then evaluate Process Cycle Efficiency (PCE), Value Added (VD), Non Value Added (NVD) activities, lead time and takt time. The current state and after the implementation of lean tools, the PCE, takt Time and lead Time is 7.79%, 61,234sec, 14.05sec/pair and 17.08%, 27,949sec, 11.16sec/pair respectively. Lean maturity of the case company assessed and Color codes were assigned for the maturity level and the assigned color codes were Green: Above industry baseline, Yellow: At or near industry baseline and Red: Below industry baseline. The green , yellow and red code for existing lean maturity were 0,17 & 3 respectively and after the implementation of lean tools the code became 11,9 & 0 respectively. By this study the lean wastage was evaluated; the existing machine layout was assessed and new machine layout is proposed using AutoCAD. After all the production flow was rearranged by minimizing several NVD times such as transportation, waiting, inspection, etc. a productivity improvement model was proposed. This model is significant as it can resolve the identified problems in awareness Creation on management and manpower, improvement strategies, future VSM, as well as continual improvement of the process. | en_US |
