Analysis of deal outcomes by lead source shows a clear correlation between where a lead originates and its likelihood to close:

• Referral leads (7 deals) achieved the highest win rate at 42.86%, with an average won‐deal amount of \$773,122.
• Partner‐sourced leads (4 deals) had a 25.00% win rate and an average deal size of \$414,840.
• Website and Event leads each generated 4 deals but did not close any (“Closed Won”) deals, yielding a 0.00% win rate, despite average opportunity sizes of \$566,116.50 (Website) and \$709,227.50 (Event).

These results indicate that referral sources deliver the strongest deal success, partner channels deliver moderate results, and purely inbound Website or Event leads underperform in closing deals. The accompanying bar chart (“lead_source_win_rate_chart”) visualizes win rates across these lead sources.
