it's normally upper managers sand baging. Everytime we have a new product they don't involve anyone later stages in pipeline and keep the engineering team in a sealed space lab IN Mars. Then release the product half baked because the eng team quit or got dissolved to work on other more important projects. Then demand the sustainability team to develop it. So now it's in limbo for 2 years but noo we must go to market now. Now it's all trash but marketing cleans it's image.
Never fails to happen.
Worst is new management come and say new product v2 but we are doing it all from scratch and ignore previous team mistakes. Like why?
