The problem is more deep than readability. I see some points of improvements.
The more important issue is uncompleted interaction which could break your business goal. The goal, as you mentioned, is to sell some product. So the interaction sequence should look like:
- Find product
- View product details
- Sell product
Instead you have only steps 1-2. Fast and efficient selling, which is your goal, is possible when you bring a value proposition for your clients. At least, operator's call to a client should sound for him as the most value proposition.
So an operator should very clear present to a client the proposition and answer client's questions fast. Consider here the phone dialog mode, which is limited to:
- just one (audial) channel. There is no more channels (visual, etc.)
- time duration, it's rather short
- human's short term memory, the words could be forgotten soon
The solution for fast and efficient product selling is to create value proposition for a client. An operator should use some pre-defined scenario when talking to a client and ask
his questions fast. This could be achieved by organizing all the product's information in accordance to some
Value Proposition Template.
Value Proposition Template you need to perform user research and analytics and develop appropriate layout, which is based on:
- frequency of the information usage
- importance of the information
- sequence of flow
Such layout will serve as the value proposition, which is formed automatically and should be delivered to a client by operator. The 3rd step of interaction (which brings money to your and which is missed currently in your interface), will look like just reading the screen!
Current layout has a lot of "failed links", which are shown in red.
