Continuous quality improvement is a very essential element of dairy laboratories' operations and activities. It ensures consistent quality of analytical outcomes and their reliability, creating high-quality products that conform to the standard specifications. Moreover, it decreases waste in time, personal effort and raw materials. This will be positively reflected on the costs as a result of reducing the additional expenses resulting from the re- work or taking corrective action. So, it is important to be interested in the implementation of one or more of continuous improvement methodologies. The aim of this thesis is to implement one of the continuous improvement methodologies in the quality laboratory of one of the factories that produce and manufacture dairy and its products. It is well-known that the most critical problems and errors that occur in the dairy laboratories are found in pre-analytical stage. For this reason, this study focuses on of the problems that occur in this stage; and works on finding the root causes of these problems to find the appropriate solutions to reduce and prevent their occurrence again through applying deming cycle )PDSA (methodology as it is short, speedy and considered an effective improvement cycle. We established a research methodology that is related to deming cycle) PDSA) implementation on the basis of the studies that have been mentioned in the following references: boughey, 2012 sited from langley et al., 1996, Plura, 2000 and weinstein and vasovski, 2004
