Different teams can understand the customer well and still make decisions that fail to connect.
A company can know a remarkable amount about its customers and still fail to understand them together.
Marketing has its data and customer research. Sales has its conversations, objections and buying signals. Product has usage data and feature requests. Delivery sees what implementation actually requires from both sides. Support sees recurring problems. Customer Success sees adoption, value realisation and risk.
None of those views needs to be wrong. And yet the decisions that follow can still fail to connect.
What marketing promises, sales sells, product builds and Customer Success later helps customers achieve may all make sense individually while creating a much less coherent picture for the customer.
The problem is not necessarily that the company lacks customer information.
It may be that different teams are making connected decisions from disconnected views of the customer.
This is where shared customer understanding matters: not because every team needs the same customer view, but because the right customer knowledge needs to reach the decisions that depend on it.
Different views are useful. The problem is where they fail to connect
Specialisation is useful.
Sales should understand buying dynamics. Product should know how customers use the solution. Delivery, Support and Customer Success will see things that Marketing or Sales may never encounter.
In complex B2B, there is rarely a single customer perspective. A champion, user, economic buyer and technical evaluator can experience the same offering very differently.
We do not need to make those views identical.
The more interesting question is what happens when decisions based on them depend on one another.
Local customer knowledge can create company-level problems
Imagine Customer Success repeatedly learns that successful implementation requires a strong internal owner and significantly more customer resources than expected.
But what happens if that knowledge stays mainly within Customer Success?
Sales may continue qualifying customers without exploring whether that internal ownership exists. Proposals may understate the effort required from the customer. Marketing and sales may continue setting expectations around a fast path to value.
Then implementation struggles.
From one team’s perspective, the problem may look like onboarding. From another, poor adoption.
But the underlying issue may have started much earlier.
Something one part of the company knew about the customer never changed the decisions another part was making.
Some customer knowledge needs to travel when another decision depends on it.
Shared understanding does not mean one customer view
Shared customer understanding does not mean giving every team identical customer information. It means giving connected decisions enough common customer context to make sense together.
The goal is not to create one enormous repository, dashboard or persona document. Nor should every team receive every piece of customer information.
What matters is whether the relevant knowledge reaches the places where it can influence another decision.
For example:
Does what Customer Success learns about value realisation change how Sales qualifies opportunities and sets expectations?
Does implementation experience change what Marketing and Sales promise?
Do recurring Support problems influence Product priorities?
Does what customers actually value after six months change the proof and stories Marketing uses?
These connections matter because the customer’s experience does not follow the organisation chart.
Marketing and sales shape expectations while also being part of the experience itself. Product and delivery shape what happens in practice. Adoption and use make it clearer whether the customer can turn the solution into meaningful outcomes. Those experiences continue to shape trust and the wider relationship.
If those learnings do not travel back into earlier decisions, the company can keep recreating the same customer problem in different places.
Disagreement can be useful too
Shared understanding does not mean everyone has to reach the same conclusion.
Sometimes Sales says customers urgently need a capability while Product sees very little usage. Support may see a recurring problem that account teams rarely hear about. Customer Success may see a barrier that never appeared during the buying process.
Those differences do not automatically mean one team is right and another is wrong. They may be seeing different customers, stakeholders, situations or moments in the relationship.
Instead of immediately trying to align everyone around one answer, it can be more useful to ask:
Which customers? In what situation? Which stakeholder? At what point? And what evidence is that based on?
Cross-functional disagreement can be a signal that there is something important to investigate.
Maybe the teams are looking at different customer groups. Maybe the same capability matters during the buying decision but is rarely used afterwards. Maybe the evidence conflicts. Or maybe the company simply does not understand the issue well enough yet.
Shared customer understanding also means knowing where the evidence conflicts and where uncertainty remains.
The useful question is not “How do we share everything?”
A better question is:
Where does something one team knows about the customer need to change a decision another team is making?
Customer understanding provides context for decisions. It does not make the decisions for you. Business priorities, market dynamics, economics, technical constraints and company capabilities still matter.
Different functions should continue to bring different expertise to the table.
The customer does not need your teams to think the same way. They need what those teams do together to make sense.
If different parts of your organisation hold different pieces of customer reality, bringing those perspectives together can reveal gaps that are difficult to see from inside one function.

If different teams hold different pieces of the customer picture, I can help turn them into a clearer shared view.
