5 Criteria for Product Success

I just rediscovered this in the book entitled "Bringing Your Product to Market" (1997) , although there looks like author Don Debelak has a revised edition.  In the introduction, he lists the 5  essential criteria for a successful product:

• The product is easy to distribute.
• The technology is simple.
• The product is perceived to be unique.
• The benefit is obvious.
• The product can be sold at 4-5 times it's manufacturing cost.

In my now over 20 years working with technologies (mostly in life sciences) and over 10 years with entrepreneurial/ early stage enterprises, I  certainly agree with all of these criteria and can unfortunately cite numerous examples where lacking one or more of these criteria  led to eventual failure in the market.
