TheCommon Service Data Model (CSDM)prescribes anincremental, maturity-based rollout approachto reduce risk and ensure sustainable adoption. The recommended order isCrawl, Walk, Run, Fly, which aligns implementation effort with increasing organizational capability and value realization.
Crawlfocuses on foundational data hygiene: core CI classes, identification rules, reconciliation, basic Discovery ingestion, and CMDB Health basics.
Walkintroduces service context, includingBusiness Services, Application Services, and relationships that enable impact analysis for Incident and Change.
Runexpands into operational excellence withService Mapping, service offerings, advanced governance, and process automation.
Flyrepresents optimization and scale, leveraging analytics, AI/ML, proactive operations, and cross-domain integration (e.g., SecOps, APM, CSM).
This progression ensures teams do not over-model early or introduce complexity before data quality and governance are established. The other options describe generic project lifecycles or organizational categorizations, not the CSDM-recommended adoption path.
Therefore, the correct answer isD - Crawl, Walk, Run, Fly.
