Applying a single attribution model, like last-touch, to all channels is a mistake. It undervalues top-of-funnel activities and can lead to budget cuts that starve the pipeline. Instead, measure each channel based on its intended outcome and funnel stage.

The company's overall win rate was low (6-7%) and decreasing. Analysis showed this decline mirrored a drop in marketing 'signals' (e.g., event attendance, content downloads) before an opportunity was created. This provided a clear data link between mid-funnel marketing activities and sales success.

By measuring success on 'last lead source,' the company was incentivized to pour money into paid search for product trials—a clear final touchpoint. This model blinded them to the higher value of other lead types and actively discouraged investment in demand creation activities that build brand and generate higher-quality leads.

Traditional funnels jump from a marketing signal (like an MQL) to an opportunity, creating a blind spot. They miss the 'Engagement' period of initial interaction and the 'Prospecting' phase of active sales pursuit. Ignoring these stages makes it impossible to diagnose performance issues or identify improvement levers.

Focusing on successful conversions misses the much larger story. Digging into the reasons for the 85% of rejected leads uncovers systemic issues in targeting, messaging, sales process, and data hygiene, offering a far greater opportunity for funnel improvement than simply optimizing wins.

Most GTM systems track initial outreach and final outcomes but fail to quantify the critical journey in between. This "ginormous gray area" of engagement makes it impossible to understand which activities truly influence pipeline, leading to flawed, outcome-based decision-making instead of journey-based optimization.

Instead of marketing and sales running separate races with siloed KPIs, a modern GTM model measures the entire journey like a relay. Both teams are measured on how efficiently accounts move through the funnel, focusing on the quality of handoffs and collaborative impact on velocity.

Profound market insights come from rigorously analyzing why potential customers fail to convert, not just studying happy ones. Tripling down to understand why a prospect "dropped out" of the sales journey provides a more complete picture of product gaps and value proposition weaknesses than focusing only on successful closes.

Legacy GTM models relegate marketing to top-of-funnel activities. Data shows marketing’s continued engagement *after* a deal is created significantly impacts outcomes. Deals with active marketing signals during the sales cycle close faster and at a higher rate, proving marketing is a full-funnel powerhouse.
