Abstract
This paper unravels some ofthe issues, ideas and challengesfaced inthefield of Value Stream Mapping. Value stream mapping enables you to identify the wastage in your processes. If an activity is not adding value to your products, it is waste and should be removed. When the value stream is analyzed, most companies are shocked as to the amount of time that no Value adding activities are taking place. Building batches and keeping it as Work In Progress (WIP) is simply adding waste to the process and extending the total processing time. Value Stream Mapping is a visual method of mapping the flow of materials and information from the time products come in from goods inwards, through all the manufacturing processes and finally ready for dispatch. Value stream mapping is a key tool in Lean Manufacturing Principles. This tool can be extended out of the confines of the organization to look at the effect your suppliers have on the complete supply chain. The advantages of VSM includes, identifying the complete production process notjust a single process, allowing identifying the sources ofwaste. The Current state map andfuture state map help form an implementation plan for change and improvement. The maps can be used to target Kaizen activities. The paper aims at reducing the lead time of a gun drill manufacturing section ofM/s. XYZ company. This organization mainly deals with production of different types of drills like, Single lip Gun drill, Twin Lip Gun drill, Helix Gun Reamer, Helix Gun Reamer with Holder. The problems faced by the company includes, the reduced average output per day, Longer Production lead-times, Reduced Value-added percentage. The results of the study after comparing the current and future state Maps yielded positives like, the output increasedfrom 51 gun drills per day to 57, major reduction of production lead-times was observed, Value-added percentage increased to 12.12%.
