Sample Answer
At my last company, we had four major product lines all using different IaC approaches: hand-crafted consoles, CloudFormation, a bit of Terraform, and some Bash scripts. It was slowing us down badly – lead time for infra changes averaged 5–7 days and we had three serious misconfigurations in one quarter. I proposed standardizing on Terraform, which immediately triggered pushback from the CloudFormation-heavy team and our security group. Instead of forcing it, I ran a 3-week spike with a cross-functional working group: two senior devs, one SRE, and one security engineer. We compared tools against criteria we all agreed on: policy-as-code, drift detection, multi-cloud support, learning curve, and blast radius. We then piloted Terraform on a non-critical service, measured a 40% faster rollout and zero manual changes. We documented the patterns, created reusable modules, and set a 6-month migration roadmap with clear escape hatches. By giving each team design input, publishing metrics, and committing to shared guardrails (OPA policies, mandatory code reviews), we turned a contentious decision into something people actually advocated for. Six months later, 80% of our infra was in Terraform and change failure rate dropped by about 30%.
