Without knowing details it's very hard to give specific recommendations. However if you follow that thread you will see folks have commented on what has worked for them.

In general I would recommend get Hyndman's (free) book on forecasting. That will definitely get you upto speed.

Wishing you the best.

If it's the case that you will ship the code over client's fence and be done with it, that is, no commitments regarding maintenance, then I will say do what the management wants. If you will continue to remain responsible for the ongoing performance of the tool then you will be better if choosing a model you understand.

MBAs do love their neural nets. As a data scientist you have to figure out what game you’re playing: is it the accuracy game or the marketing game? Back when I was a data scientist, I got far better results from “traditional” models than NN, and I was able to run off dozens of models some weeks to get a lot of exposure across the org. Combined with defensible accuracy, this was a winning combination for me. Sometimes you just have to give people what they want, and sometimes they want cool modeling and a big compute spend rather than good results.
