A journey map has one lane. Awareness, consideration, decision, and a single figure sliding along it, acquiring feelings at each stage.
Your buyer is not one figure. It is a group whose members enter the process at different moments, evaluate different things, hold different amounts of risk, and are frequently not in the room together. The finance lead joins at the point where the technical lead has already ruled out two options. The eventual sponsor may never read a page of your site. The person who kills the deal often never spoke to you at all.
Mapping an average member of that group produces a description of nobody, and it is the same failure as an over-specified persona: a composite that no actual person matches.
Here is what is actually known about these groups, what is not, and what to map instead.
Start by discarding the number you have been using
Almost every deck about B2B buying committees opens with the claim that a complex purchase involves six to ten decision makers.
That claim never carried a published methodology. The page that hosted it for years contains no sample size, no fieldwork dates, no definition of what counts as a decision maker and no link to a report. And it is no longer there: comparing archived captures of the same page, the sentence is present on 8 October 2023 and absent on 25 October 2023, while the page itself continues to exist and continues to discuss buying groups at length.
What is published, with a method attached, is narrower and more useful. A survey of 632 B2B buyers conducted in August and September 2024 reports that buying groups range “from five to 16 people across as many as four functions”. That is an observed range, not an average, and the report behind it sits behind a client wall.
The same survey produced two findings worth more than the headcount:
74 percent of buyer teams demonstrated unhealthy conflict during the decision process.
Groups that reached consensus were 2.5 times more likely to report that their deal was high quality.
Which relocates the problem. The interesting variable is not how many people are involved. It is whether they can agree, and what your material does to help or hinder that.
There is one body of evidence on group decisions with real stakes, real careers and a real sample, and it is not from marketing.
Researchers analyzed 1,804 promotion and tenure decisions across six universities: 906 made under joint evaluation, where several candidates were considered together, and 898 under separate evaluation, where each was considered alone. These are committee decisions, made by professionals, with irreversible consequences.
The evaluation format changed the results, controlling for productivity, institution, rank, discipline, department size and funding. That is the first finding.
The second is the one that should worry anyone building a sales process. The researchers surveyed 289 professors who had actually served on such committees and asked what they expected. Only 17 percent anticipated the direction of the effect. 43 percent expected the opposite.
The people running the process were, in the majority, wrong about how the procedure they used shapes what it produces.
That generalizes cleanly to a buying committee, and it is the argument for treating the shape of the evaluation as part of your selling, rather than as something that happens to you. Whether your proposal is read alongside a competitor’s or on its own is not a neutral detail. It changes what the group weighs.
The mechanism is well documented. When two options are seen together, attributes that are impossible to judge alone become readable, and their weight rises. In the founding experiment, participants offered $19 and $27 for two used dictionaries seen side by side, and $24 and $20 for the same two seen one at a time. The preference reverses. Alone, you weight what you can actually assess. Compared, an attribute you could not interpret becomes interpretable.
In a deal, the attributes nobody can judge from a single document are the ones that decide it: whether your scope is generous or thin for this category, whether your lead time is normal, whether your price is high. Every one of those is unreadable in isolation and obvious in comparison.
The standard fix for a bad journey map is to interview the buyers. Do it, and ask the right thing, because the wrong question produces confident fiction.
A foundational 1977 paper established that people have little or no direct introspective access to their own higher-order reasoning, and that when they explain a decision they draw on plausible causal theories rather than on any actual observation of their own process.
A 2005 experiment in Science made this concrete. Participants chose between pairs of faces on attractiveness, and the experimenters secretly handed back the face they had not chosen. Most failed to notice, and then explained, confidently and in detail, why they had chosen it. The authors named the effect choice blindness.
Add the sensitivity problem. A review in Psychological Bulletin concluded that misreporting on sensitive topics is common and situational, and that respondents “edit the information they report to avoid embarrassing themselves in the presence of an interviewer.”
Now list the questions a vendor typically asks in a win-loss interview. Why did you leave your previous supplier. Who actually made the decision. Why did you not choose us. Every one of them is either an introspection question or a sensitive one, and often both.
The questions that survive this are factual and sequential. When did the project start. What triggered it. Who was in the first meeting. Which documents circulated internally. What was the alternative you compared us against. What was the last objection raised, and by whom. Those have answers people can actually retrieve, and they are checkable against the deal record.
One structural feature of a committee has no equivalent on a journey map: several of its members will form a view of you without any contact.
The theory here is clear even where the measurement is thin. The foundational 1993 article on brand equity holds that raising awareness “increases the likelihood that the brand will be a member of the consideration set, the handful of brands that receive serious consideration for purchase.” Getting into the set is the mechanism. It happens before anyone visits your site.
Two consequences follow that most maps miss.
The first is that in a business purchase the relevant task is recall, not recognition. The same article notes that recognition matters more “to the extent that product decisions are made in the store”. A committee decision is not made in a store. It is made in a meeting where somebody says who else should we be looking at, and the answer comes out of memory, unprompted, in front of colleagues. Being recognizable when someone lands on your page is a different capability from being retrievable when your category is the cue.
The second is that the standard against which you are held is set by whatever else came out of memory in that meeting. Which returns to the point above: the frame of reference is not chosen by you, it is assembled in a room you are not in, and it determines which of your attributes are readable at all.
Replace the lane with three things you can actually observe.
Entry points, not stages. Different people enter for different reasons and at different moments: a contract renewal date, a failed audit, a departure, a regulatory deadline, a growth threshold that broke a process. Map the triggers, and note which function notices each one first. That tells you who to be findable by, which is a different answer for each trigger.
Artifacts, not touchpoints. A committee does not carry your website into its meeting. It carries a document: a comparison someone built, a summary written by the internal champion, a page printed from a proposal, a spreadsheet. Ask which documents circulated internally and you learn what your material actually became once it left your control. That is the object your case has to survive in, and it is usually shorter and blunter than anything you produced.
Objections and their owners, not feelings. Every deal that stalls has a last objection and a person who raised it. Record both. Over twenty deals you will find that a small number of objections recur, that each belongs to a specific function, and that some of them are never raised in front of you. Those are the ones worth building material for, and they are invisible on a journey map because the person who holds them never appears in your analytics.
Assume comparison, and supply it. Given the evaluability evidence, a proposal that arrives without a frame of reference is being read on whatever the reader can judge, which is usually price and length. Providing the comparison yourself, honestly, including where you are not the best option, is not generosity. It is controlling which attributes are readable.
Write for the person who will not be in the room. If the internal champion has to represent your case in a meeting you will not attend, the useful deliverable is the one they can hand round: short, checkable, and free of anything that requires you to explain it. There is a media consequence as well, and our page on B2B paid acquisition sets out how audiences get built around the several functions that have to agree rather than around one job title.
Optimize for their consensus, not for your enthusiasm. The one survey with a published method found unhealthy conflict in three quarters of buying teams, and a strong association between reaching consensus and reporting a good deal. Material that helps a group agree with each other is doing something the research supports. Material that excites one person and threatens another is doing the opposite.
Stop citing a committee size. Nobody measures it publicly. Ask each buyer how many functions were involved in their case, keep your own count, and use that. It will be more accurate for your market than any published range, and you will be able to say where it came from.
The point is not that journey maps are useless. It is that the object they model, one person moving through stages toward a decision, is not the object you are selling to. You are selling to a group that has to agree, whose members judge your offer against whatever else is in front of them at the time, and who will reconstruct their reasons afterward with total confidence. Map that, and the map will be uglier and considerably more useful.
Frequently asked questions
How many people are in a B2B buying group?
Nobody measures it publicly. The figure of six to ten never had a published methodology and was removed from its publisher's page in October 2023. The primary measurement behind it was 5.4 people in 2014. The same publisher now reports a range of 5 to 16 across up to four functions, from 632 buyers surveyed in 2024.
What is wrong with a customer journey map in B2B?
It models one person advancing through stages. A committee has no shared position: its members enter at different moments, evaluate different things, and are not all in the room at the same time. A map of an average member describes nobody in the group.
Does the format of the evaluation matter?
Measurably. Across 1,804 real promotion decisions, evaluating candidates together rather than one at a time changed the outcomes. And only 17 percent of surveyed committee members correctly anticipated the direction of the effect, while 43 percent expected the opposite.
Why does the same proposal get judged differently in different meetings?
Because attributes differ in how easy they are to judge alone. Seen against a competitor, a hard-to-evaluate attribute becomes readable and gains weight. In experiments, the same two options reverse their ranking depending on whether they are seen together or separately.
Can I just ask the buyer what happened?
You can ask what happened. Do not ask why. People reconstruct their reasons from plausible causal theories rather than from introspection, and questions about a lost supplier or an internal decision are sensitive enough that answers get edited in front of an interviewer.
