What I need to learn

As soon as we passed the 4th external audit in row without non-conformances I started to browse the internet to look for the options I have. I’m focusing on German speaking countries, because my intention is to learn German together with my family. I filtered on quality, test and project management I’m good at, and after a few days I realized that I need to learn additional methods, like FMEA, PRINCE2, SixSigma and Lean. Generally I know what they mean and how they work but I haven’t had my own oppinion on them. I used FMEA once, and I found it very powerful, but I cannot try it in reality.  SixSigma and Lean will be easy with the help of L.P.,  who uses them daily. I’m afraid I’ll need to learn PRINCE2 myself…
