Central procurement may set the commercial frame, while regional marketing and implementation owners decide whether the work is usable in a local market. Record those decision rights before comparing providers. Define what central procurement standardizes: access ownership, reporting, approval workflow and deliverable acceptance. Let regional teams supply customer context, language review and market-specific facts. Confusing those responsibilities creates a global contract that nobody can operate locally. For the regional-partner scenario, use a responsibility matrix in the selection meeting. Ask who resolves conflicting feedback and what happens when a local reviewer misses a deadline. Evaluate the proposed escalation path before it becomes a live project dispute. ## Define the central and regional decision rights Create a responsibility map before requesting proposals. Central procurement can standardize access, commercial terms and reporting, while regional teams validate local customer facts and language. Name the role that resolves a disagreement between brand consistency and local clarity. Ask candidates how they would operate that process. The goal is not more approvals; it is knowing which approval actually permits work to move forward. ## Use a regional pilot in the supplier evaluation Select one region with a willing reviewer and a meaningful delivery task. Ask the candidate to explain how it would collect local input, produce a draft, implement changes and obtain acceptance. Keep the sample bounded so it tests the working method rather than demanding a full unpaid strategy. Record what another region would need to repeat the process, including any market-specific research that cannot be reused. ## The working sequence - Separate central standards from local decisions - Define the central and regional decision rights - Use a regional pilot in the supplier evaluation - Make renewal evidence portable - Review the next bounded decision Move to the next stage when the evidence is usable, not simply because a calendar date has arrived. ## Make renewal evidence portable Agree which files, decisions and records remain available if the supplier changes. A central team should be able to see what each region received and which issues remain open. Avoid a reporting arrangement where only the agency knows how its score was calculated. The renewal conversation should compare accepted delivery and unresolved needs across regions, without treating a single successful local project as proof of universal fit. ## What to put on the comparison sheet On narrow screens, scroll the table to see all columns. Questions to take into the agency discussion | Selection criterion | Evidence to request | Acceptance record | | Decision rights | Central, regional and technical approval owners | No deliverable depends on an unnamed approver | | Pilot evaluation | One region with real review constraints | Regional team accepts the work before rollout | | Portability | Editable deliverables and evidence exports | Renewal does not depend on vendor-only access | ## Ask for the evidence behind one relevant case Choose one case that resembles your sales model or delivery problem. Ask what the agency actually controlled, what changed, how the baseline was collected and what other activity happened during the period. A polished chart without definitions is an invitation to ask questions, not a reason to assume the result will transfer. A useful case discussion includes a limitation: a channel that did not work, a dependency that delayed implementation or a measurement gap. Ask who would work on your account and how that person contributed to the example. Team availability matters more than the agency having once employed a specialist. ## Bring proposals onto one cost sheet Separate agency fees, media spend, production, software, translation and your own implementation time. Check whether meetings, reporting, revisions and access handover are included. A cheaper fee can become more expensive when your team must create every asset or implement every technical recommendation. Do not demand a fabricated fixed price from an incomplete brief. Ask for assumptions, a bounded first phase and the conditions that would change the estimate. Compare the same time period and deliverables. Resolve ambiguous ownership before signing rather than treating it as a detail to settle during the kickoff. ## A question for your next meeting Which named role signs off the local facts, and who accepts the completed implementation?
