This is super true, until a point where you're making signs by the location & new builds only, at which point you are dealing with widgets, those widgets are small sign shops, and you need to leverage all of these critical business skills to strong arm them into getting signs on the wall at midnight. At that point we call them a national and their rate is at least 25% beyond what local customers pay...
Business is business. The whole idea of a "widget" is exactly that, it doesn't matter what product or service you produce (the widget). The principals of business are the same whether you're running a sign shop or running a strip club. Or both if you're from Arkansas?
I'm not saying it's all bad, just do the right stuff, in the right scenario, and for the right purpose. Real business training is different, human resources, accounting, book-keeping and records management is a lot different, and more useful than what you get with business coaches, advisors, and these over priced courses...
Before I retired, the firm I was with spent a fortune sending key people like me to these courses, hiring coaches and advisors to shadow us... Never asked for it, it just became part of the job, and dropped our profit sharing to almost nothing for 2 years.
We started small, and grew to national, specializing in large major trade show exhibits, store POP/ POS displays, product branding, plus all the general signage and graphics we still did for the local market. We went from a little company doing the decals, banners & graphics most of us do, to runs of hundreds & thousands of store displays, both graphics and manufacturing, and we had growing pains. In our case most of what they pimped we had already figured out and implemented before any of it just using common sense in our workflow to streamline things. It didn't take us to new levels. I found most of it pretty textbook generic, some even admitted that our "job shop on steroids" didn't fit in their box (but they were sure happy to take the check at the end, and credit for what we had already done before they showed up). Probably could have gotten the same info and outcome from a $20 book, but that's just me.
I don't see where a 1-3 person sign shop that caters to a small local market would get any value from these types of things. For a small shop, the internet is full of resources, business webinars, papers, publications, and you can find ones that are more industry specific than all the coaches, advisors, and courses that aren't geared to any specific industry. Plus these resources are either free, or relatively cheap compared to courses and coaches that cost as much as putting a new printer in your shop. The one thing they aren't is cheap.
But you do get some pretty fancy looking certificates to hang on your wall. I feel more edumacatededed.
And thanks Notareal, now I wanna' move to Arkansas and open a shop.... Maybe I'll grow my mullet back too
