Focusing - advice

I want some opinions.....we have built an interactive e-learning platform which offers course creation, quiz creation and roleplay.

The e-learning and quiz element was for a very specific market and we have struggled to translate this to tangible sales. We have a couple of users on this but growth is slow.

I'm thinking about concentrating solely on roleplay as a sales, customer service and engagement training tool. This will focus on only one element rather than trying to offer 3 different components.

The roleplay is essentially a scenario training tool currently using email and live chat but with voice about to go live.

We have done outreach and content marketing so far but with 4 products in one, I've struggled to get our messaging across.

Am I on the right tracks? I work in my own so bouncing ideas is often a challenge...
