What is a product?
The object of the exchange process.
Provided by the supplier in return for something of equal or greater value.
Fulfils demand, where demand is a business opportunity.
(Baker & Hart, 1999. Product strategy and management)
A great product isn’t just a collection of feature. It’s how it all works together.
Marco Arment, founder of Instapaper.
If an asset does not create value for its customers and users, and for the company, then I don’t regard it as a product.
Roman Pichler
A product is a hammer, and a service is someone holding the hammer and hammering for you.
Patrick Quattlebaum and Jamin Hegeman
