Reliability Methods Harmonization – My Internship Experience at Dräger

Caroline Bild im Büro_1Hello! My name is Helen. I am from Indonesia and currently studying Industrial Engineering at Swiss German University. I am an intern in Product Quality anReliability Engineering Department at Dräger Safety in Lübeck. An internship in Germany is mandatory for all sixth semester students at Swiss German University. The internship I am doing in Germany right now is different from the internships in Indonesia and also very special! Therefore, I am extremely excited to share this unforgettable internship experience.

Why did I choose Dräger Safety? Initially my main goal for this internship was only to do an internship in Quality Management. I had no clue which company I would choose. But then I came up with a name: Dräger. Why? A safety product requires a serious quality management. Well, moreover, Dräger is a worldwide company, and Dräger also operates in Indonesia. Therefore, I gave it a try and was literally jumping for joy when I was accepted!

During my internship at Dräger, I gained numerous knowledge and life lessons. Very helpful and bright colleagues contributed in making my internship experience remarkable and memorable. Another important thing during internship is „trust“. They trusted me to support some pieces of their work. Without their trust, I would not have gained so much knowledge and experience.

In this internship I was involved in a project called Reliability Methods Harmonization. For those who have no clue about what reliability, reliability methods and reliability methods harmonization are, imagine a miner who owns a Dräger gas measurement device. He absolutely want his device to be functional every day under his working condition. If the device fails to function for only 1 day, he may not know whether dangerous gas level exceeds the threshold. This can be dangerous. Therefore, as the producer, Dräger perform some procedures to assure that the product will still perform its function for a certain period under certain working conditions. These procedures are called reliability methods.

Some of the methods are risk mitigation process (where risks of a product are identified, evaluated and mitigated), analysis of failure and failure effects of product before market launch (where possible product failures are identified and actions are defined), and field data analysis (where data about what failures occur on the field and how many failed products are identified and analyzed). The procedures cannot stand alone, they should coordinate and relate to one another. For instance, during analysis of product failure before market launch, we should refer to field data obtained during field data analysis to know what actual failures occur in the field. This coordination and relation will later be called harmonization.Bild_Grafik

When the methods are not harmonized, it will take more time and more effort to perform them. For instance, if field data describing existing product failure is not used as the input for product failure analysis before market launch, we need to figure out by ourselves more possible field failures. 

Therefore, harmonization of those reliability methods is important and I am happy to be a part of this important project.

Thank you Dräger for giving me this priceless opportunity!
