  • Selecting a provider for runbooks without validating the API surface behind them

    Automation depth can vary when integration complexity or target system constraints are present, which DXC Technology calls out in how throughput depends on workload partitioning and change windows. Require evidence of API-driven provisioning and event-driven workflows for managed operations, not just documented procedures.

  • Treating RBAC as an access-only feature instead of an operator action governance layer

    Governance must cover operator actions tied to provisioning, change, and environment access, which IBM Consulting and Managed Services and Capgemini Managed Services explicitly frame with RBAC-aligned access controls. Ask for examples that include RBAC enforcement during change approvals and during operational tasks.

  • Ignoring audit log scope for schema changes and access decisions

    Audit log coverage should include provisioning actions and access decisions so investigations can trace changes, which TCS Infrastructure Services and Wipro FullStride emphasize. Define required audit events up front and include retention expectations for who altered configurations and schemas.

  • Underestimating governance gates that can slow iteration for frequent changes

    Governance gates can add friction for high-frequency changes without pre-approval paths in Capgemini Managed Services, and automation design overhead can constrain fast iteration without clear governance in Accenture Managed Services. Create an approval model that distinguishes low-risk changes from schema-impacting changes so automation can run within defined gates.
