There is an existing solution for everything that a person wants to do or accomplish.  That solution (a unique combination of a product, service, and process) is “sticky”.  People have an affinity for an existing solution, even though they know it’s not perfect.  People need a reason to change to a new solution.

There are two types of new solutions that could cause people to change.  One type of solution is new and different.  The other is new and better.  

A new and different solution improves the user experience within the design constraint of the existing solution architecture.  A new and different solution tends to emphasize increasing solution novelty.

A new and better solution improves the user experience  by changing the solution architecture.  A new and better solution tends to emphasize reducing net trouble compared to the existing solution.

The tension between “new and better” and “new and different” solutions is the Trouble / Novelty Paradox.  Resolving the Paradox as a dual factor solution, rather than prioritizing a single factor in the new solution, is an essential step in developing an innovation.

Every Innovation resolves the Trouble / Novelty Paradox to provide a better net user experience with less net trouble than the solution it replaces.  

Always.
