For resellers/integrators, it always feels uncomfortable rolling out a new product for sale to your customers. Granted, not everything 'new' is always 'risky', but the less is known about a product the worse the uncertainty is.
This blog post suggests testing first on 'the three Fs":
"After it passes this first step, try it (new product) out on the three Fs – friends, family and focus groups. An outsider might catch obstacles that were overlooked.
“Once we determine the benefits, we have to figure out the low hanging fruit in the market – who needs this service?” Again, the three Fs can provide essential information in this regard. You can also go right to the source. Don’t be afraid to ask the tough questions to prospects "
Personally I have never used these '3 Fs' as test subjects. In fact, the opposite was true - the last thing I wanted was to flub up a design or install buggy equipment for anyone, much less family or friends.
I think this advice is crazy, but maybe I am wrong. What do you think? Are your friends & family your 'test subjects'?
