THE APPARENT CONDITION

A brand audit comes back clean. The logo is used correctly everywhere. Tone of voice guidelines are followed across email, social, the website, sales collateral. Colors match. Typography matches. Every channel owner can point to the brand guide and demonstrate compliance. On paper, and often in the room where this gets reviewed, this reads as evidence that the marketing is coherent.

It is evidence of something. It is not evidence of that.

THE MARKETING PROBLEM

Brand consistency is a real and necessary achievement. It ensures the market recognizes the company as itself across contexts. But consistency operates at the level of presentation — how something looks and sounds. It says nothing about what is actually being claimed, promised, or argued across those presentations. An organization can be perfectly consistent in voice while being materially contradictory in substance.

This happens not through negligence but through the ordinary mechanics of how marketing gets produced. Different channels are frequently built, optimized, and approved by different people, working from different immediate objectives, all operating within the same brand guidelines. The email team is optimizing for engagement and may lean into approachability and speed. The enterprise sales deck, built to justify a premium price to a buying committee, leans into rigor and exclusivity. Both are on-brand. Both pass every tone check. And a prospect who encounters both in the same evaluation cycle is now holding two different claims about what this company actually is.

THE DISTINCTION

Consistency is sameness of execution: does this look, sound, and feel like it comes from the same organization.

Coherence is integrity of argument: do the claims made across these executions support one commercial position, or do they compete with, undercut, or contradict one another.

These can move independently. An organization can be highly consistent and deeply incoherent — every channel is unmistakably “on brand,” and yet the promises being made are not the same promise. An organization can also, in principle, be less polished in execution while remaining coherent — rougher at the edges, but saying one consistent thing everywhere it appears.

The reason this distinction is easy to miss is that consistency is what gets audited. Brand guidelines produce checklists: logo usage, color, tone, terminology. Coherence has no equivalent checklist, because it isn’t a property of any single channel — it only exists, or fails to exist, across channels. A reviewer looking at any one asset in isolation cannot detect an incoherence that only appears when that asset is placed next to another one the same prospect will also see.

THE EVIDENCE

Research on integrated marketing communication has documented the importance of coherence across customer touchpoints, while inconsistent or contradictory communication can increase confusion and reduce confidence in what the organization is actually promising.

This tracks with how marketing organizations are structured. Channel teams are typically evaluated on channel-specific outcomes, which gives each team a reasonable, locally rational incentive to shape messaging for that channel’s performance logic. No single team is doing anything wrong. The incoherence emerges at a level no single team is responsible for monitoring — the level of the whole argument, across all the places a buyer might encounter it.

The distinction also holds up against the more obvious explanation: that this is really a governance problem, or a systems problem, about who approves what. It isn’t. Two channels can go through identical, well-functioning approval processes and still contradict each other, because the approval process is checking each piece against the brand guide, not against every other piece the buyer might see. The contradiction is not a process failure. It is a coherence failure that consistent execution and sound process can both fail to catch.

THE DECISION CONSEQUENCE

Once this distinction is visible, a clean brand audit stops functioning as reassurance about the underlying marketing argument. It confirms presentation. It says nothing about substance. Leadership evaluating whether the marketing “hangs together” needs a different question than the one a brand audit answers.

The more useful question becomes: if a single buyer moved through every channel we operate in — saw the ad, opened the email, read the case study, sat through the sales conversation — would they encounter one position, or several. This is not a question about tone. It’s a question about whether the claims survive being placed next to each other.

This also reframes what “fixing” the problem looks like. The instinct, when incoherence surfaces, is to tighten brand guidelines further. But guidelines govern presentation. They don’t govern argument. Two perfectly on-brand executions can still make incompatible claims, because the guideline never asked them to agree with each other — only to look like they belong to the same company.

THE IMPLICATION

Coherence has to be evaluated where it actually lives: across channels, not within any one of them. A single asset cannot be incoherent by itself; it can only contradict something else. That means the review that matters most is not the review of any individual piece of marketing, but the comparison between pieces a real buyer would plausibly encounter together. Consistency can be confirmed one asset at a time. Coherence cannot.
