"Fly" isn't a phase of CSDM as you are thinking of it. It is not a phase of a product or service lifecycle. Rather, it is a phase of adoption of CSDM, or an indicator of maturity level in the CSDM maturity model. Practically, what this means is that people who are new to CSDM should generally focus on their Foundation and Crawl phases first -- make sure your platform foundation data, your infrastructure, and your applications are managed -- and their Fly phase last, focusing on your business capabilities, information objects, and service catalog associations. Even in that context, it's not as much an order of operations as it is a matter of what data builds upon other data, and it is acknowledged that different customers can address components is different order according to their specific business needs. For example, you may already have a service catalog, and that's fine, but in order to align your service catalog to CSDM, you need to have defined service offerings first, which generally is considered secondary to defining the deployed applications that you are supporting.
