I've been hosting a weekly radio talk show for some time now. I work with publicists and PR agents who set up interviews for me with book authors from across the country. Over time, I've learned how to pick out "good" books. There are certain factors that come together and that make it obvious that the book will do well. It involves much more than the actual book. It's the entire marketing and selling of the book, which is a complex set of factors that come together to make it a success.
I find something similar when it comes to plastering products. Just like books, there are certain factors that come together that make it pretty clear that a certain product will succeed. Now, it's one thing for a company to discover, produce or import a product for use in plastering. It's quite another to have a definite "plan of action." I've seen wonderful products that companies represent but they don't have a clue on how to market or distribute what they have. Talent in marketing and sales seem to be lacking big time, which either stunts the growth of the company or kills it altogether over time.
