Abstract: Combining with the actual situation of the design steps in the process of engineering construction, enumerated the types of design change, and from the angle of the design unit, the causes of design changes and their influences on design units were analyzed from internal and external aspects.  The design changes of a company in recent years were studied and analyzed by using various mathematical statistical methods such as fishbone diagram, histogram, pie chart, etc. Relative modification rate of design change and the change rate of design change cost were introduced to determine the key causes and key links of design change, and propose corresponding control measures. Combined the actual conditions of engineering company, this paper used mathematical statistics method to make statistics and analysis on design changes, continuous improved the company's quality, and which had an important reference value and a wide range of reference value.
