New PM looking for advice, particularly for developing back-office tools Hi all! I'm starting as a new Product Manager this week (previously worked in an Ops role exposed to Product in a diff company) and looking for some advice on how to approach my first few weeks. 

I currently don't have engineering resource so looking to learn anything and everything I can about the product. It's a tool that supports a back-office team - at a basic level, it identifies individuals who have fallen into debt and drags them into an automated comms cycle. Just looking for general advice on who I should be speaking to / key things to find out in my first few weeks.

A PM worked on the original product but been deprioritised until now (biz objectives to reduce revenue loss)

TL:DR; new PM looking for advice for my first weeks
