Which process would be used to compare the value that newer services have offered over those they have replaced?

Availability management focuses specifically on ensuring services meet agreed availability targets and does not perform comparative value assessments across service generations.

Capacity management is concerned with ensuring sufficient capacity exists to meet current and future service demands and does not evaluate relative business value between services.

Service portfolio management maintains visibility across the full service lifecycle, encompassing pipeline services, the active service catalogue, and retired services. This comprehensive view enables organizations to formally evaluate and compare whether newer services have delivered greater value than the services they replaced - a function no other process provides.

Service catalogue management only tracks services that are currently active and available to customers, so it has no visibility into retired services and cannot support this type of comparison.
