Fit-for-All Prophet Model - Not a Good Idea

Image
After completing the debugging on Prophet model yesterday, I still think that building a #Prophet model that aims to fit-for-all (e.g., business units) is NOT A GOOD IDEA . Yesterday my team member, Cang Zheng, and I were assisting one of our Prophet users in debugging her reserve figure generated from their existing Prophet production model (which was developed earlier by other modelers). When we went through the Prophet model, although it was not modified from the standard Conventional library, we still found traces that it is modified from a library that aims to achieve fit-for-all purposes.
