CSDM gives organizations a prescriptive foundation for modeling services and the supporting enterprise landscape, but there is an architectural tradeoff that I rarely see discussed: at what point does increasing model fidelity cost more to govern than the traditional business value it produces?
For a large hybrid enterprise with acquisitions, legacy, applications, shared platforms, cloud services, outsourced services, and inconsistent ownership maturity, how do experienced architects determine the minimum level of Business Application, Application Services, Technical Service, Service Offering, and CI relationship fidelity necessary to support impact analysis, change, risk, portfolio planning, operations, and executive reporting?
What objective criteria would determine whether another relationship or layer in the CSDM is worth creating and governing?
And what measures would you use to demonstrate that CSDM maturity is improving business decisions rather than simply increasing CMDB completeness?
