Continuing education as a technician — Which path has more future

Would like to qualify me even further and am not quite sure which direction could make sense for me or would like to hear your opinions. My previous career: # 2000 – 2003 Training as a mechanic # 2003 – 2010 Working in a profession # 2010 – 2012 Continuing training as a technician # 2012 – date Working as a technician To be well prepared for the future I want to be more broadly positioned. Since I (by the way 36 years old) don’t really want to be so much more qualified. A) Acquisition of the additional qualification to become a technical manager at the technical school Gotha (no IHK examination) in 12 months Part-time https://www.fs-gotha.de/…/ B) Putting on certificate courses such as Production & Lean Manager Tüv Süd, Sex Sigma Courses, IPMA Project Leader Training,… Which way do you think is the better alternative? What is better for the future? What will a potential new employer in the CV more appeal to from the career path? The professional goal is to continue to be a “maker” who tackles but also assumes project responsibility and management. What do you think of the offer of the specialized school Gotha in comparison to the IHK Betriebswirt? What is the value in comparison? Or do you necessarily have to study and everything other than a Bachelor makes no sense?
