If the underlying or lower-level platform is not well defined or stable, the upper platform will itself be unstable, and unable to provide the firm foundation needed to accelerate software delivery within the rest of the organization. If the underlying platform has operational quirks or performance problems, the platform team group will need to build insulation abstractions and workarounds for the operational problems, and/or advertise the potential problems to Dev teams and make it easy for them to avoid hitting the problems.
