Is there also a term that describes this phenomena ?
"Each year we get an update for product X with a few minor changes that makes the new version parts incompatible with the previous year version (maybe not all parts are incompatible).
I noticed this with washing machines, I wanted to buy a similar model with something that I own and they made a different model, redesigned the outside, maybe small changes inside.
I also know that cars get updates each year, some stuff gets changed on the front of the car to look "better" but now under the hood some parts do not fit and need to be moved around and redesigned, then the car needs to be tested again.
I think it would be healthy to launch a product, then in first year(s) analyze the defects your products get, next product would be an evolution that addresses the issues.
I agree if you have new ideas on how to improve your product go ahead and make the new version but don't make a new model of a microwave that is identical with previous one except you changed the shape, moved some buttons and added a gimmick feature.
