Choose the right perspective
Match the person's scope to your decision, since running one site or region, a global operations organization and a SaaS infrastructure team pose different problems. Check whether their relevant role is current or past, and ask which capacity, reliability or vendor decisions they owned directly.
Questions to take into the conversation
- 01How do you decide when to add capacity, and which signals tell you demand will outrun the current infrastructure?
- 02Where do handoffs between engineering, operations and supply chain teams slow down a deployment or an incident response?
- 03How do you weigh building and running your own infrastructure against using third-party data centers or providers?
