A broad Google Cloud practice claim needs workload-specific evidence. Match the proposed people, architecture, operating artefacts, and customer reference to the data, AI, platform, or operations work you are buying.
BigQuery and data-platform work
Ask who owns data modelling, pipeline reliability, data quality, access, retention, workload performance, and cost controls. Google documents separate on-demand and capacity-based BigQuery workload models; a data partner should explain when each is relevant and how it will monitor query behaviour and reservation use. Require acceptance criteria for data completeness, latency, reconciliation, and downstream reporting—not only infrastructure deployment.
GKE and application platforms
Pythian's AllSaints case covers infrastructure and monitoring; SADA's 2022 Heretto case covers a joint support call with Google Cloud that resolved a GKE issue before launch. Neither establishes full lifecycle platform management. The proposal should assign cluster and application duties: upgrades, node pools, policy, observability, releases, dependencies, service objectives, and rollback. Have the team walk through a platform upgrade that exposes an application incompatibility and an incident where cluster health is normal but the business service is slow. Their response should name who detects and diagnoses the problem, authorizes changes, and communicates with your team.
AI and model operations
Onix's telecom case reports a deployed customer-care application; its unnamed customer and historical usage window limit what a buyer can verify. Evite's future AI possibilities and general AI service descriptions need separate delivery proof. Require a comparable production reference and a proposal covering data access, evaluation criteria, deployment, observability, security, cost limits, human review, and ownership when model or pipeline behaviour changes. Identify which artefacts and code transfer to your team and which components remain dependent on the provider.
Managed operations and shared responsibility
Google Cloud's shared-responsibility guidance remains relevant when a partner is added: the MSP can operate agreed controls, but the customer still needs clear accountability for data, access, regulation, and application behaviour. Require a responsibility matrix for projects, folders, billing accounts, identity, security, data, incidents, cost, and exit assistance.
Compare the final proposals against the same resource inventory and service objectives. Record assumptions, exclusions, subcontractors, support locations, third-party tooling, transition work, and separately charged changes. In a working session with the proposed delivery lead, review an architecture decision, a failure scenario, and the first operating report they would produce. Add unresolved responsibilities and missing evidence to the proposal clarification list.
