Background: The company has had a low outgoing delivery precision for a prolonged period. This creates problems as orders must be prioritized in order to be produced on time and partial deliveries are used to satisfy customers. The origin of the problem is unknown to the company, but there are suspicions that the problems arise in production. Purpose: The purpose of the study is to contribute to an improved outgoing delivery precision for Företag X. A current state analysis from the inbound to the outbound flow is conducted to find causes of delays. The study creates a prioritization basis for the company to identify the most critical article groups. This creates a tool for decision support, linked to delivery precision, for manufacturing companies. Methods: This study is a case study at Företag X. The study uses secondary data in the form of quantitative data from the company's business system, but primary data in the form of interviews and the author’s own observations. The data is used to create a cause and effect diagram and to perform an ABC/XYZ-analysis on the company's inventory that forms the basis for segmentation of the articles. Conclusions: The study's conclusion is that Företag X's low outbound delivery precision is due to several reasons such as communication gaps, insufficient production planning and measurement & variation in load. The most important cause is production planning. In order to improve this, other causes must also be solved first and Företag X must follow the priority order that the study has developed. Through this, Företag X can get a better outbound delivery precision and a more efficient flow.
