So they can be a mixed bag IMO. The general impression I get from customers is that the team conducting it on AWS side can also make all the difference. You also need to set your expectations around what comes out of this. I think if you are looking for a starting point, they are good. If you get a good team on the AWS side, even better. If you need something deeper with tactical action items, there are better assessment approaches (especially when you have to cover tech outside of AWS e.g. GitHub repos, CI/CD pipelines, hybrid cloud etc.). For example if you want to get a good handle on security around DevOps and your cloud environment, you might want to consider conducting a DSOMM assessment and building a roadmap off that
