This study aims to research variation at a startup company and to understand what methods are necessary to root out and eliminate quality issues. The study is conducted at Biotech AB which is a producer of Bio-instruments as well as bio-ingredients that are produced on site for customers. The company has been concerned with the amount of variation in internal quality coming from the production and the purpose of this study is to find what is causing the variations and what preventative actions need to be taken. This study has been a mix between a quantitative and a qualitative study with its base being around the records of errors given through quality logs. Several interviews were made as well as observations in working procedures and working instructions. The results showed that five major issues were causing the most concern and unnecessary cycles in production, namely featured parts and human error also cause these variations. The interviews indicated that processes need to be managed better and faster due to the rapid pace of the company growth. They also indicate that the communication doesn't always work and needs to flow freely in both directions. The level of waste is quite high in forms of physical waste and time wasted due to cycles in production. Lean thinking needs to be implemented and 5s needs to be made aware of to give everyone a quality and waste-free working ethic from the ground up. Many of these issues could be solved by implementing a quality perspective by giving constant feedback according to TQM.
