Chapter 11 — The Eternal War of Attribution
"Marketing sourced that pipeline. Sales will tell you they sourced it. The customer will tell you they Googled it at 11pm in a panic. All three are lying, and only one of them has a dashboard." — Skyler Dunn, CMO, Synergaeon, in the war-room Slack thread that has 412 unread replies
And lo, in the beginning there was a buyer, and the buyer did a thing, and then later the buyer bought. Between the thing and the buying there fell a great darkness, and into that darkness every department of Synergaeon, Inc. did reach its hand and claim the credit. This is the Eternal War of Attribution, and it will not end, for it cannot end, for it is not a math problem. It is a custody battle.
The Unknowable First Cause
Attribution is the practice of assigning credit for revenue to the marketing and sales touches that "caused" it. The problem, which every attribution vendor will sell you a solution to and never mention again, is that you cannot observe causation. You can only observe correlation wearing a lanyard.
A buyer at a mid-market logistics firm saw a Synergaeon LinkedIn ad in March, ignored it, attended a webinar in April because of the free swag, got nine emails from SDR-7 (none opened), read a competitor's review, asked a friend, sat on it for a quarter, then signed in September because their old vendor raised prices. Which touch caused the deal?
"The honest answer is 'all of them and none of them and also the friend, who is not in your CRM,'" said Priya Venkataraman, VP of RevOps, rubbing the bridge of her nose. "But you cannot put 'a friend' in a pie chart, so we pretend the webinar did it."
This is the First Theological Crisis of attribution: the data ends at your firewall. Dark social — the Slack DMs, the WhatsApp threads, the "hey is Synergaeon any good" texts — is invisible and is also, by everyone's quiet admission, where most deals are actually born.
The Models, and Their Holy Limits
The tribes worship different models. Learn them, for you will be asked to defend one in a QBR while Chad Brindleworth III stares at you.
First-touch attribution gives 100% of the credit to the very first recorded interaction. Marketing loves first-touch, because Marketing usually owns the first touch (the ad, the SEO page, the gated whitepaper no one read). Its lie: it pretends the buyer's nine-month journey was decided by a banner ad, and it makes top-of-funnel look like a hero while ignoring everything that closed the deal.
Last-touch attribution gives 100% to the final interaction before purchase. Sales tolerates last-touch and Finance secretly likes it because it's simple. Its lie: the last touch is almost always "the demo" or "the sales call," which means last-touch reliably concludes that Sales closed every deal entirely by itself, a finding Dirk Mallory considers self-evident.
"Salesforce says I sourced zero pipeline last quarter and closed $2M," said Dirk. "That's not attribution. That's just the relationship, brother."
Multi-touch attribution (MTA) splits credit across many touches. This is where the holy wars get baroque:
- Linear: every touch gets an equal slice. Fair, simple, and wrong, because not every touch matters equally. The opened email and the 40-minute pricing call do not deserve the same dignity.
- Time-decay: touches closer to the close get more credit. Good for understanding what closes, bad at crediting the awareness work that started everything.
- U-shaped (position-based): 40% to first touch, 40% to the lead-creating touch, 20% spread across the middle. The diplomatic treaty model — it pays tribute to both the kingdom of Awareness and the kingdom of Conversion.
- W-shaped: 30%/30%/30% to first touch, lead creation, and opportunity creation, with 10% to the middle. Adds a third sacred checkpoint (the moment Sales got involved) so Sales feels seen.
- Full-path / Z-shaped: W-shaped plus a fourth weighted moment at the close. The "everyone gets a trophy but weighted" model.
Data-driven attribution (DDA) is the supposed promised land: an algorithm (often Shapley values from game theory, or a Markov-chain "removal effect" that asks how much would conversions drop if we deleted this channel?) assigns credit based on actual marginal contribution rather than a rule someone picked in a meeting. It is the most defensible and the least trusted, because nobody can read it.
"I built the data-driven model," said Janet from RevOps, to no one. "It's a Markov chain. It's genuinely good. They turned it off because the pie chart 'looked weird' and went back to U-shaped."
The limit of every multi-touch model is the same: it can only weigh touches you tracked. Garbage tracking in, confident pie chart out. A model is just a rule for dividing credit you already can't verify.
Sourced vs. Influenced: The Two Holy Books
Here is the distinction that ends marriages.
Pipeline sourced means a channel created the opportunity — it was the originating touch. It is a single, jealous, winner-take-all number. There is exactly one source per deal, and everyone wants to be it.
Pipeline influenced means a channel touched the deal at any point. It is generous and promiscuous — a single deal can be "influenced" by Marketing, the SDR swarm, the field event, and the customer's own webinar binge. Influenced numbers are always enormous, which is why Marketing reports influenced pipeline in board decks and Finance squints.
"Marketing influenced $80M of pipeline this quarter," announced Skyler. "We have $40M in ARR," said Brenda Okafor, Revenue Accounting, not looking up. "Influenced is not sourced. Sourced is not booked. Booked is not recognized. That's not pipeline, that's a feeling with a UTM parameter."
Both numbers are real. Both are true. They measure different things and are constantly presented as if they measure the same thing, which is the entire war in one sentence.
Self-Reported Attribution: The Heretic Sect
A growing tribe has abandoned the dashboards entirely and simply asks the buyer: "How did you first hear about us?" — a free-text box on the demo form. This is self-reported attribution, and it is heretical because it is unstructured, unjoinable, and embarrassingly more accurate than the multi-million-dollar attribution stack. It catches the dark social. It catches "my buddy uses it." It also catches "Google," which the buyer types when they mean "the LinkedIn ad I forgot about that made me Google you." Even the truth lies a little.
Why It's Political, Not Analytical
Here is the load-bearing heresy of this chapter: attribution is not primarily an analytics function. It is a budget-justification and credit-allocation function dressed as one.
Every attribution model is a decision about who gets to keep their headcount. First-touch funds the awareness team. Last-touch funds the AE org. The model you pick determines whose budget survives the next "right-sizing of human surface area" that Tobias Crane is already drawing an up-and-to-the-right slide about.
This is why Skyler Dunn owns fourteen dashboards that all disagree: each one is a weapon optimized for a different battle. You do not pick the correct model. You pick the model whose conclusion you can survive.
"Stop asking 'which model is right,'" wrote Dr. Lance Vesterberg in Predictable Revenue Is Dead. "Ask 'which model makes my team look load-bearing.' Then, and only then, present it as objective." (He meant this as advice. It is, horrifyingly, also a confession.)
The mature move — Priya's move — is to stop treating attribution as a verdict and start treating it as directional: use it to decide where to invest more, not to litigate who won. Run two models side by side. Accept that the gap between them is the size of your ignorance, and that the ignorance is permanent. Use sourced for accountability, influenced for understanding the full motion, and self-reported as the tiebreaker that keeps you honest about the dark social you'll never see.
You will never know why anyone bought. You will only know who is willing to fight about it.
The Commandments of Attribution
- Thou shalt not confuse sourced with influenced, for one is a king and the other is a crowd.
- Thou shalt pick a model and disclose it, for an undisclosed model is just a vibe with decimals.
- Honor the dark social, the deals born in DMs thou shalt never track, and be humble before them.
- Thou shalt not put "a friend" in the pie chart, though a friend closed it.
- Self-reported attribution is heresy and also correct. Both. Always both.
- Use attribution to invest, not to convict. It points; it does not prove.
- Remember that every model is a budget, and every budget is a headcount, and every headcount is afraid.
And the war did not end. And it shall not end. For as long as two departments report to the same Number and only one set of trophies exists, the buyer's true reason shall remain sealed in the one record no CRM can hold: the buyer's own mind. Amen, and per my last Slack.
