Where selection and delivery commonly break: governance gaps, schema churn, and automation scope drift
Common failures happen when data model governance and admin controls are treated as afterthoughts or when integration scope expands without a stable schema target. Providers including PwC and Deloitte tie automation to controlled workflows and RBAC-aligned governance, while others show how missing ownership coordination can reduce throughput.
The mistakes below are derived from real delivery constraints and limitations described across the provider set from AtkinsRéalis to ERM.
Choosing a provider without upfront data ownership for schema control
AtkinsRéalis and WSP both describe best outcomes requiring upfront definition of data ownership, which prevents schema alignment delays. Deloitte and PwC can also slow delivery when RBAC, audit scope, and configuration change ownership are unclear.
Assuming extensibility without an audit-preserving validation workflow
Ricardo and AtkinsRéalis connect extensibility to governed configuration and audit-friendly change tracking, which prevents untracked schema drift. KPMG similarly focuses on lineage and audit log requirements, while providers like Aurecon stress that extensibility depends on integration contracts and client schema choices.
Under-scoping the automation and API endpoints needed for real integrations
PwC notes that API automation depth varies by engagement scope and client source complexity, which can leave integration endpoints under-specified. WSP and Deloitte handle API-driven extensibility more explicitly, but implementation scope can still expand if integration endpoints and workflow hooks are not defined early.
Over-investing in automation without ensuring RBAC and audit log traceability for changes
AtkinsRéalis and EY emphasize RBAC-style access patterns and audit log traceability, which protects governance during schema evolution. ERM similarly includes RBAC-style governance and audit logs for sustainability record changes, while approaches that treat admin controls as secondary tend to increase coordination overhead.
Relying on delivery-only sandboxing for high-throughput testing and schema iterations
PwC describes that sandbox extensibility for high-throughput testing may be limited per engagement, which can slow test cycles. KPMG and EY frame testing support as more delivery-led than productized, so teams should plan validation workflows and throughput requirements early.
