I'm the technical geek, so it's often I've heard: Folks say, with a smirk, "technical types hide in the back room...while the (neatly dressed business suited) accounting types run the business.
Only partly true, but someone like me fits that concept, of somehow never aquires enough practical everyday business skills.
So the 'calculator / pocket protector' Engineer types think they generate the revenue, while the Accountant 'bean counters' think they generate the revenue.
Actually, it's the CUSTOMER generating 'the revenue'.
I'm curious about 'Mechatronics' example meaning, and for example, what kind of percentage mix, across those different skills; like are you 20 % software, 40 percent hard circuitry...that sort of thing.
I had idea, more of a product plan than an invention, the consumer product w/b (that means 'would be') a POCKET SHOWER. I could say 'Go for It!' but that little portable thing would cost $
to develop, and safety certification(s).
Plus not sure, but could get into Patent status issues, if you could develop some novel improved pump or heater, for the hand-held Pocket Shower.
I tried going the (US) Patent route, to riches. Heck we've all tried routes to get the gold.
Whenever I contemplate starting a small business I :shutter, quietly,...and make funny noise, softly.
I was: Burglarized, (local meth addict most likely), I got extortion, (and that was the 'friendly staff' in the building), lost a lot of friends (they said I needed to get a job), and generally went 'grey haired'.
BUT, thats the 'badges of honor' you endure, it ain't for the meek, IMHO.
Preparation-wise you could possibly benefit from taking some more school courses, if you have a Community College or University nearby.
Try adding, possibly, a Business Major curriculum to your skill set. In past years, folks liked to find a Mentor,
someone older / successful. Try to look for companies that offer 'apprentrice' stints, like 6 months working at a bio-sciences business.
You have to look at everything, such as availability of appropriate travel or re-location depending on opportunity. (Sounded like you maybe would rather run your own biz, rather than getting job at XYZ Corp.)
Don't forget luck: luck can be at work, if you let it.
I'm better at purely technical stuff. Any reasonable PM questions, from a beginner, send your questions. There is a HUGE quantity of expertise, hanging out on this EEVBLOG.
