The problems identified at the case company were synthesized to reflect on which performance indicator they affect by utilizing the studies of various researchers. Furthermore, 24 lean tools associated with lean warehousing presented and validated by different researchers were identified and they were characterized into seven based on their management techniques. The wastes in warehousing of the case company were assessed seven principle of wastes which directly apply to a distribution warehouse. Interview with employees, first hand observation and collection of responses from questionnaire a sample size of 16 people was instrumental to analyze the wastes at each stages of the warehousing activities. The root cause of these wastes was analyzed by using combination of the 5W 1H history analysis method and 5 Whys root cause analysis technique and then Pareto analysis was utilized to recognize significant causes of warehousing problems. Consequently, twenty two cases were identified and these problems were further clustered to seven based on the notion they represent. Afterward, it was necessary to identify which warehousing issues correspond to the problems stated in the problem statement. To analyze that, a questionnaire was distributed amongst 73 sample population in which the analysis was undertaken by using Relative Importance Method. With that regard, Storage System, Standardization, Existing Human Resources, Warehouse Design and Training were found to be attesting to the problem statement. The next step taken after the identification of causes of major warehousing wastes was to identify which lean management tools can have an impact in solving these root causes. The sample size for questionnaire distribution and analysis for this step is similar to that of the previous step. With that regard, Continuous Improvement Management, Human Resource Management Lean Tools and Product and Process Management Lean Tools were found to have an impact in solving the warehousing issues at the case company. The findings of this research indicate that the warehousing problems at the case company can be solved by utilizing the above mentioned lean management techniques and the tools that they are comprised of.en-USWarehouse Management, National Oil Ethiopia PLC (NOC), Lean WarehousingWarehouse Management Improvement Model via Lean Warehousing for the Case of National Oil Ethiopia PLC (NOC)Thesis
