I've seen under the apple skirt, and the incentive structure there is such that these issues are inevitable. You get more RSUs and promotions when you make something new, and not when you make something simpler and more robust.
Do you have an example of a company which has been successful with an alternative incentive structure that doesn't have these issues, perhaps one that pushes for more siloed products and rewards employees based on ongoing financial success?
The best incentive I’ve ever had wasn’t financial. It was having an incredible boss whom I DID NOT WANT TO DISAPPOINT.
