Abstract	This Master’s Thesis was based on a case study at Astra Tech, a company operating in the Medical Device Sector. What distinct this sector is the requirements for high quality and cleanliness. Lately Astra Tech had experienced problems with high scrap rate, low resource efficiency, and long throughput times in the production flow of one of their product families. The purpose of this Master’s Thesis is to understand how to improve a production flow within the Medical Device Sector using Lean methods. Three methods were selected to study the effects Lean methods could have on the production flow, i.e. Value Stream Mapping, Seven plus One Wastes, and Overall Equipment Efficiency. Initially an understanding of the production area and the organisation as a whole was gained through observations and interviews. Value Stream Maps of the current state were made for the three characteristic production flows that were considered in the study. The production flows were analyzed using the Seven plus One Wastes. The efficiency of the flows was then measured by the throughput time. Based on this, future states were developed and compared to the current state of the flow. The measurements for Overall Equipment Efficiency was gathered as secondary data and analyzed to see what influence it has on the production flow. The study showed that the used methods were useful in order to get an understanding of how to improve a production flow within the Medical Device Sector. By using the methods, the throughput time could theoretically be decreased for all three production flows (by 89%, 90% and 99.4% respectively) and thereby making them more efficient.
