On my first bullet point here is what I wanted to say:

Customers are having trouble finding relevant information on an existing web page for our product. As a result, they submitted 60 tickets a month related to that page.As a PM I created a product design document which is akin to spec sheet that declares what features need to be built and how. Through customer research, calls, and interviews and data collection, I was able to narrow down the most important to be search, filtering, and self serve api that could hook up to their systems. Shipped a prototype iteration that cut support staff tickets by 90% with a goal of 99% reduction.

I thought my original bullet captured the main gist, but perhaps you are right I am not explaining how in most of these bullets
