Pitfalls that break governed performance work
Several integration and governance mistakes show up across providers that deliver performance work with automation and schemas. Early enforcement of RBAC and audit logging can slow iteration if ownership and access decisions happen too late or too rigidly.
Another recurring pitfall is starting automation without committing to stable schemas and API contracts, which leads to rework in interface mapping and provisioning workflows. Boston Consulting Group and Slalom call out that schema and data model commitments depend on scope and discovery rigor.
Starting automation before schema and interface contracts are owned
Require explicit schema and API contract ownership before orchestration runs, because G42 notes that clear ownership of schemas and API contracts avoids churn during performance tuning. Capco also ties automation depth to agreed interface contracts and system ownership.
Enforcing RBAC and audit logging too early without access workflow design
Design RBAC roles and audit log expectations as part of the rollout plan so provisioning is not blocked, because G42 reports early cycles can slow if RBAC and audit logging are enforced immediately. DXC Technology and Slalom emphasize governance-led provisioning and RBAC alignment to avoid uncontrolled change.
Treating extensibility as late-stage configuration changes
Use documented interface contracts and controlled configuration so extensibility does not trigger schema churn, because Capco and G42 frame extensibility boundaries and configuration discipline as design inputs for safe rollout.
Assuming legacy telemetry coverage will be available without integration effort
Plan integration work for instrumentation gaps and telemetry access because Infosys highlights instrumentation gaps in legacy systems and Sogeti notes performance tuning deliverables depend on access to telemetry.
Skipping reusable automation artifacts and relying on one-off scripts
Request reusable automation patterns or artifacts, because Boston Consulting Group notes API and automation surface documentation is not always delivered as reusable artifacts.
