Timeline
Single source of truth achieved in 90 days
The Challenge
Marketing and Sales had different numbers. Every board meeting devolved into arguments about who sourced what. Nobody trusted the data.
Symptoms
- Marketing claimed 70% of pipeline was marketing-sourced
- Sales claimed 70% of pipeline was sales-sourced
- Three different attribution reports showed three different stories
- CMO and CRO couldn't align on pipeline targets
- Budget discussions were political, not data-driven
Root Causes
- No agreed definition of 'marketing-sourced' vs 'marketing-influenced'
- Multiple tracking systems with conflicting data
- UTM parameters inconsistently applied
- No clear handoff point defining source attribution
- Self-reported lead source was primary attribution method
Impact
Leadership couldn't make investment decisions. Marketing couldn't prove ROI. Sales blamed Marketing for bad leads. Marketing blamed Sales for not following up.
The Diagnosis
Mapped the entire lead-to-revenue journey, identified all touchpoints, and reconciled data across systems to understand the real customer journey.
Key Findings
- 1.65% of closed-won deals had both marketing and sales touches
- 2.Self-reported source was wrong or missing 40% of the time
- 3.First touch was marketing for 75% of deals (even 'sales-sourced')
- 4.Average deal had 12 marketing touches before close
- 5.Only 15% of deals were truly single-touch (outbound only)
Maturity Score Changes
The Solution
Strategy: Create a unified attribution model that both teams agree on, with clear definitions and a single source of truth.

- Implemented linear multi-touch attribution as primary model
- Created first-touch and last-touch reports for comparison
- Built pipeline report with both sourced and influenced views
Phase 3: Operationalization
30 days- Trained both teams on new definitions and reports
- Built shared dashboard for weekly pipeline review
- Created SLA for marketing-to-sales handoff

Qualitative Outcomes

Key Lessons
- 1Attribution is a team sport - both sides must agree on definitions
- 2Perfect attribution doesn't exist - agree on 'good enough'
- 3Multi-touch is closer to reality than first or last touch
- 4Data quality must be solved before attribution modeling
- 5Shared dashboards and regular reviews maintain alignment
