Terminology governance: why consistent does not always mean uniform

Terminology decisions are not small details. They shape how content is written, translated, reviewed, reused, and understood. In medical and life sciences communication, these decisions need to balance accuracy, audience needs, regulatory context, and practical content management. Good processes should support good language decisions; they should not replace them. In this article, I look at what terminology governance means in practice, why consistency should not be confused with uniformity, and how a clearer approach to terminology can help teams create content that is both coherent and fit for purpose.

Most teams want their medical content to be consistent, and rightly so.

Consistent terminology can make content easier to review, approve, reuse, translate, and maintain over time. But consistency becomes less useful when it is treated as a rule to apply the same wording everywhere, regardless of audience or context.

In specialist content, the better question is not always “Are we using the same term?” It is “Are we using the right term, in the right place, for the right audience?”

This is where it becomes an operational concern: if terminology varies, does that not make content harder to manage?

It is a valid concern.

Terminology decisions are not just “this or that” choices. They can affect timelines, review rounds, consistency across materials, and how usable the final content is for its intended audience.

When teams are working across multiple documents, reviewers, countries, and content types, a single uniform solution can feel easier to control. It seems easier to maintain, to reuse, and to explain.

However, as people say: “easy is not always best”. Language does not exist in isolation. It has to work in context.

When consistency becomes oversimplification

There are two different ways to think about consistency.

The first is uniformity: choosing one term and applying it everywhere.

The second is contextual consistency: using the right term, in the right place, for the right audience, and doing so systematically.

A term that is precise and appropriate in clinician-facing content may not be the clearest choice for patients. And wording that helps patients understand a symptom, condition, device, or procedure may not be specific enough for regulatory, scientific, or technical materials.

Applying one term across all content may simplify internal workflows. But it can also make the content less clear, less accurate, or less usable.

For example, an HCP brochure, a patient leaflet, and an internal training deck may all refer to the same clinical concept: dyspnea.

In an HCP brochure, “dyspnea” may be the appropriate term because it aligns with clinical usage and is recognized by healthcare professionals. In patient-facing content, “shortness of breath” may be clearer and more immediately understandable. In an internal training deck, both may be needed: the technical term to align teams with clinical terminology, and the plain-language wording to show how the concept should be explained to patients.

The question, then, is not simply which term is correct.

It is which term is correct for this audience, this document, this context, and this purpose?

That is where terminology decisions become more than wording preferences. They become content decisions.

What terminology governance actually means

Terminology governance does not have to mean a heavy process, a complex database, or another layer of approval. At its simplest, it means agreeing on how key terms should be used, documenting the reasoning, and making those decisions easy for everyone involved to apply.

It is not just about creating a glossary. In practical terms, terminology governance helps answer questions such as:

• Which term should be used?

• Is there more than one acceptable option?

• Does usage change depending on the audience?

• Does usage change depending on the document type?

• Should the term be explained at first mention?

• Are there terms that should be avoided?

• Who approved this decision?

• Where is the rationale recorded?

• How should writers, translators, reviewers, and local teams apply it?

Without this structure, terminology decisions tend to be made case by case. They may depend on who is reviewing the document, which legacy files are being reused, how much time is available, or which term happens to appear in an earlier version.

That is when inconsistency becomes a problem – because there is no clear logic behind the variation.

Governance is not about making language rigid

The word “governance” can sound restrictive, but good terminology governance should not make content rigid. It should allow for flexibility where needed, while making sure that flexibility is controlled, documented, and purposeful.

The important point is that terminology decisions should not be improvised every time. They should be clear enough that anyone working on the content knows what to do and why.

Using the example above, a useful terminology note might say:

Use “dyspnea” in clinician-facing, regulatory, and scientific materials. Use “shortness of breath” in patient-facing materials where plain-language communication is required. If both audiences are addressed in the same document, introduce “dyspnea” with a plain-language explanation such as “shortness of breath” at first mention, then use the agreed approach consistently thereafter.

That kind of note is much more useful than simply marking one term as “preferred” without explaining the conditions for its use.

Why terminology choices should not be driven by convenience alone

Understandably, teams want terminology to be easy to manage. When content is reused, translated, adapted, reviewed, and updated across multiple documents and markets, simplicity has real operational value.

But terminology decisions should not be driven primarily by what is easiest to manage behind the scenes. They should be driven first by accuracy, context, audience, and purpose.

If a terminology choice makes content easier to maintain internally but less clear or less appropriate for the intended audience, then the process is no longer supporting the content. It is starting to override it.

That is the wrong way round.

Good processes should support good language decisions. They should not replace them.

This is also a cost and efficiency issue. When terminology decisions are unclear, the same discussion can happen repeatedly across different documents, languages, and review cycles. A small decision left undocumented at the beginning can become a recurring source of edits later.

Good terminology governance helps avoid that. It gives teams a shared reference point, reduces guesswork, makes decisions easier to explain, and helps everyone involved work from the same logic – even when the wording itself needs to vary by audience or document type.

When terminology governance becomes especially important

You do not need a complex terminology process for every small piece of content. But terminology governance becomes especially useful when the same content will be adapted for several audiences, translated into one or more languages, or reused across campaigns, studies, products, or markets.

It is also particularly helpful when several reviewers or local teams are involved, when patient-facing and professional materials are being developed in parallel, or when previous projects have led to repeated terminology debates or conflicting feedback.

In these cases, terminology needs to remain consistent over time, not just within one document or one project.

In these situations, a terminology decision made in one document can easily affect several others, especially when materials are reused, adapted, or translated later.

Practical ways to improve terminology governance

Terminology governance should not be an afterthought. If you are commissioning medical writing, translation, localization, or content adaptation, a few small steps at the beginning of a project can prevent a tangle of inconsistencies later.

1. Define audience and purpose before choosing terminology

Before writing, translation, or adaptation begins, clarify who each document is for and what it needs to achieve.

Is it for healthcare professionals, patients, caregivers, internal teams, regulators, payers, or a mixed audience? Is the priority technical precision, patient understanding, regulatory alignment, training, awareness, or practical use?

These questions matter because the same concept may need to be expressed differently depending on who needs to understand and use the information.

2. Share existing guidance and known terminology issues

Before the project starts, it helps to share any existing terminology and content guidance, including glossaries, terminology lists, style guides, brand language guidance, and approved materials from previous projects.

It is also useful to flag terms that must be used for regulatory, scientific, legal, or brand reasons, as well as terms that should be avoided or have caused disagreement in the past.

Finally, determine who will review and approve the content, as this can affect terminology decisions and help prevent conflicting feedback later in the process.

If the content is complex, high-stakes, or intended for several audiences, a short discussion at the beginning can save significant time later. It can also prevent one of the most common problems: terminology being debated only after the wording has already been used across multiple documents. At that stage, changes are more difficult, more expensive, and more likely to create knock-on effects.

3. Record the rationale, not just the term

A useful terminology decision record might include:

Concept	The medical or scientific concept being described
Preferred wording	The term or phrase to use
Audience/document type	Where the wording applies
Accepted alternatives	Terms that may be used in specific contexts
Terms to avoid	Wording that should not be used, with reasons if relevant
Rationale	Why this decision was made
Approval source/date	Who approved it and when
Notes for future use	Guidance for writers, translators, reviewers, or local team

This does not need to become an administrative burden. The aim is not to document every word. The focus should be on documenting the decisions that are likely to affect clarity, accuracy, review, reuse, or consistency across materials.

A good terminology record should be easy to read, easy to update, and easy to apply. If people cannot find it, understand it, or use it during a project, it will not support consistency.

4. Plan for mixed-audience materials

Mixed-audience materials are often where terminology decisions become more difficult.

In these cases, it helps to define the strategy before drafting or adapting the content. Possible approaches include:

• Using the technical term with a plain-language explanation at first mention

• Using the patient-friendly term throughout, if comprehension is the priority

• Using technical terminology in headings and plain-language explanations in body text

• Creating different versions of the content for different audiences

The key is not to mix terms casually. Introducing two terms and then alternating between them may seem like a compromise, but it can create confusion if readers are not sure whether both terms mean the same thing or whether there is a distinction between them.

5. Review legacy wording before reusing it

Many terminology problems come from older content.

A term may appear repeatedly in previous materials, but that does not necessarily mean it is still the best choice. It may have been used because of an old source text, a previous reviewer’s preference, a market-specific decision, or simply because no one had time to revisit it.

Before carrying terminology forward, it is worth asking: Does this term still fit the audience, purpose, and current context?

If the answer is no, it may be time to update the terminology guidance and document the reason for the change.

This is particularly important when older materials are being repurposed for new audiences, new markets, new formats, or new channels. Content reuse is efficient only if the reused content still works.

6. Align on key terminology early

Terminology decisions are harder to fix late in the process.

Where possible, align on key terminology before writing, translating, or adapting the full set of materials. Depending on the project, this may involve medical, regulatory, marketing, patient engagement, localization, and local market teams.

This can be as simple as a short terminology alignment step at the beginning of the project. Before work begins, identify 10–20 key terms that are likely to affect clarity, accuracy, review, or reuse. Agree on any audience-specific wording, document terms that should not be used, and clarify who has final say on terminology decisions. As the project moves through review, update the terminology record instead of leaving important decisions buried in comments or email threads.

This small investment can reduce repeated reviewer comments, conflicting edits, back-and-forth, or late-stage changes.

Rethinking consistency

The terms chosen during writing shape later adaptation, review, approval, translation, updates, and reuse. If the original content is unclear or inconsistent, those issues tend to multiply downstream. This is why medical writers and medical translators both have a role to play.

A medical writer can help build terminology choices into the original content from the beginning, identifying key terms, flagging audience-specific wording issues, and creating language that is easier to adapt and maintain.

A medical translator can identify where a source-language term does not transfer neatly onto the target language, where local usage differs, or where a literal equivalent may be accurate but not understandable for the intended audience.

In both cases, the value is not only in producing the final text. It is in helping teams make informed language decisions that support the content over time.

Ultimately, the key to consistency is making sure terminology is used in a way that is clear, appropriate, and aligned across content, even when it varies by audience or purpose.

That is a more demanding standard than always using the same term everywhere. But it is also the one that supports clarity, usability, and long-term content quality.

So instead of asking: Can we use the same term everywhere?

A better question is: What terminology approach will help each audience understand and use this content correctly?

This is the kind of consistency your content needs. Because the goal is not to make every document sound the same. The goal is to make sure every document works for the people it is meant to serve.
