Quality Assurance and Satisfaction with Their Results : An Application to the Implementation of EN 9100 Standard in the Spanish Aerospace Sector

The objective of this study is to analyse how certain factors may influence satisfaction derived from the positive effects of implementing the EN 9100 Standard in the Spanish aerospace industry. A multiple linear regression model has been created, which includes data gathered from 115 valid questionnaires received from companies in this industry. The results of this model show that the length of time since first adhering to the EN 9100 Standard, the predominant motivation (internal or external) driving the implementation of the standard and the level of satisfaction with the prior implementation of ISO 9001 are significant variables that affect the level of satisfaction with EN 9100; whereas the size of the company is not a significant factor
