From metrics perspective, it's no different from standard product metrics. I've seen many different metrics frameworks being used, all of which essentially boil down to these 4 metric categories:
1. Operational metrics: Is the product functioning as expected? Success rates, Latency etc.
2. Usage metrics: Is the product being used? DAU/MAU, Frequency of use, customer retention/churn, Requests/sec, data volume etc.
3. Satisfaction metrics: Are customers satisfied? In-product feedback (thumbs-up, thumbs-down), NPS scores via surveys etc.
4. Impact metrics: How is the product helping customers achieve business impact? This is subjective and need to be defined per product and is also typically based on customer scenarios.
