At-a-Glance Comparison

EPC Group Decision Framework

1. M365 Copilot first. Every Copilot rollout starts here. Foundation.

2. Add Copilot for Sales if Dynamics 365 Sales OR Salesforce + dedicated sales force exists. Without an active CRM workflow, Copilot for Sales is wasted.

3. Add Copilot for Service if Dynamics 365 Customer Service OR ServiceNow OR Salesforce Service Cloud is the primary service platform.

4. Add Copilot Studio if 5+ custom agent use cases identified. For 1-2 custom agents, M365 Copilot extensibility is sufficient.

5. Add Security Copilot if SOC team has 5+ analysts and mature Sentinel + Defender deployments. Below that, the consumption cost is hard to justify.
