Pick up as many different versions of the book...
"Marketing Mistakes" you can afford.
A new version releases every few years.
Read through both the failures + successes Hartley covers.
Many of these businesses... at least the successful ones use a lean product cycle.
One of my businesses produces powder mixes. We do produce on demand, where inventory usually turns in days, sometimes hours.
Another of my businesses is a high traffic hosting company.
The product produced is hosting services, so product cycle is zero time. A person comes on as a client. I add their site(s) to a new or existing LXD container + they start paying instant continuity.
Best lean product cycles tend to be high dollar, continuity based services.
