Understand the goal of the customer service platform:
What is the main business goal of this company and how is the customer service platform serving the company goals?
For this question, I'm assuming the user journey is that customers come to the customer service platform when they run into issues. Thus, ultimately the customer service platform is feeding into the top line business metric of customer retention. Do customers keep"
