Failure analysis workshop
NHL University of Applied Sciences, Leeuwarden - The great unknown cause!
From six o'clock, soup and sandwiches will be ready for participants, as usual by now.
This is the third meeting already as part of knowledge exchange meetings of the Royal Institute of Engineers at NHL Hogeschool. tonight's theme is "Failure Analysis".
At 18:30, Bart Smit's workshop will start. It promises to be a spirited programme focusing on finding the unknown cause. The great thing about this workshop is that it follows on from the "Root Cause Analysis" workshop. This was conducted by problem detective Harry Draijer on 27 May 2015.
After a short presentation on the RATIO steps*, in which Event Mapping is central, we get to work on a case ourselves. The case is about barbecues. We are a team of experts and troubleshooters in the new factory of the company "Star-Grill" in Romania. The management asked us to help with an urgent problem. Namely, in the production of the Q60 (barbecue type) the rejection rate is 4% while it is normally 0.5%.
Like real detectives, we set to work. Among us problem detective Harry Draijer. But how do we tackle it now? First we read the whole story carefully. Then, by asking the right questions, a so-called Event Map emerges. This clearly shows what the problem is, the causes and consequences, and the 'unknown cause'. This cause is further analysed.
Using the WHAT, WHEN, WHY, HOW much and TREND, we map the IS and IS NOT of the unknown cause. Then we go through all the questions and see if they qualify as possible causes. The possible cause that scores on the most questions is the most likely cause. That is verified with the most correct cause resulting in the analysed cause. In our case: the wash tanks do not wash the Q60 barbecues sufficiently clean!
The follow-up discussion with a movie about the vibrations in Rijkswaterstaat tower in Utrecht (click on the link) led to nice causes and consequences. If we apply the RATIO steps to this, it turns out that proper failure analysis is taboo in these kinds of major social issues. We needed only 3 questions from the Problem Analysis to solve the problem.
Inspired and enthusiastic, most participants went home around a quarter to 10. Who knows, we might manage to put the knowledge and experience from this evening into practice!

* RATIO approach stimulates creative and critical thinking. This forms the capstone for all activities and provides guidance from thinking to doing. The RATIO approach provides a sustainable, structural and successful method for jointly solving and preventing problems and continuous improvement. RATIO stands for Reflect, Analyse, Assign, Implement and Observe and Evaluate.
Description
Failure analysis workshop, what do you do with an unknown cause?
It will be a punchy programme focusing on determining the unknown cause, coming up with possible causes and testing them. It follows on from the earlier workshop in which the failure was analysed to the unknown cause, this is the step after it.
What will the programme look like?
18:00 Getting acquainted
18:30 Introduction Event Mapping
19:00-21:00 ProblemAnalysis
- Theory
- Practice with a case
21:15 Closing
Naturally, there will be room for discussion and questions afterwards. Soup and bread will also be provided.
