If you want to introduce a new product, it should at least have the following 3 basic components:
Did you add "new" features to your product?
Are the features useful?
Does the end user value the features?
Do the features differentiate your product from your competitors products?
- Ease of use
Is your product intuitive and easy to use?
Will the end user be able to use a great deal of the new features without reading the manual?
Is the product "idiot proof"?
Is your product well designed?
Does your product look different from your competitors product?
Does your design appeal the end users?
Do people want to buy your product to look different?
Is your product making a "statement" about its users?
The Apple iPhone is an example of the above. It offers a lot of functionality (phone, e-mail, browser, calendar, contacts, GPS, iPod, games, camera, ...), it is extremely easy to use (no manual needed) and the design is absolutely fantastic.
