Start with the sites and applications.
List the locations included in the project and the applications people depend on at each one. Add current services, observed issues, planned changes, and the practical impact of an interruption. That brief helps the buying team ask providers for a design tied to the operation.
Keep access and network management distinct.
SD-WAN uses software-defined policies to manage traffic across network connections. The underlying access services still need their own review. Ask who supplies each connection, what is available at each address, and which responsibilities sit with the carrier, the managed provider, and your team.
Ask about failure scenarios.
Give the provider a practical scenario: a branch loses a connection, an application becomes difficult to use, or a site cannot reach a service. Ask how the issue is detected, who investigates it, and how responsibility moves between parties. Record what the proposal includes and what it assumes.
Compare each site explicitly.
A single commercial proposal can contain very different installation conditions. Ask for the service, equipment, dependencies, and estimated delivery assumptions for each location. Mark any unverified availability as an open item rather than a confirmed part of the design.
Bring contract dates into the plan.
Record current renewal dates, planned moves, and the constraints that could affect a transition. Ask the responsible commercial specialists to review the proposed terms and the treatment of delays or changes. Keep these dependencies beside the technical comparison.
Define support ownership.
Agree who takes the first call and who coordinates issues that cross access, network, and application boundaries. Ask what reporting the operations team will receive and how performance concerns will be reviewed. A support model should describe the work as well as the contact details.
Finish with an acceptance plan.
Document how you will confirm that each site meets the agreed requirements and who signs off the change. Assign ownership for unresolved items and the first service review. Use the Decision Brief to summarize the project before you request an advisory conversation.
