I'm a data scientist and I used to be pretty proud of my work, I tried to be statistically rigorous with everything I've created and my coworkers were all happy with the work. Recently though, the upper management of my company changed and consequently everything has to change, the higher ups used to do things a certain way and cannot bother to listen to anyone below them, so all the tools I've created are being discarded for worse versions. All things considered, my job is pretty comfortable, but I cannot help feeling incredibly frustrated with the complete lack of power I have in the situation.
