The sales and presales teams here do the convincing. However in my previous experience, we:
1. Find the decision maker
2. Find the check writer
3. Find their key influencers
4. Find out their current program SWOT, especially focusing on excessive spend, contract and/or regulatory compliance risk, security posture
5. We craft a message showing them how ITAM can remediate their pain pints while actually contributing to business acceleration, increased revenue, and increased profitability
