Introduction
Technical command of submission requirements, regulatory pathways, and agency expectations is what gets someone hired into regulatory affairs. It is not, on its own, what determines how far a career in the field goes. Past a certain point, most experienced professionals in a given therapeutic area or product category know roughly the same regulations. What separates the ones who get pulled into strategic decisions from the ones who stay in an execution role is a skill regulatory affairs rarely trains for directly: the ability to influence people who do not report to them.
This is a look at why that skill matters more as a regulatory affairs career progresses, what it actually looks like in practice, and how to build it deliberately rather than waiting to absorb it by accident.
Why Influence Matters More as You Advance
Early in a regulatory affairs career, the job is largely about execution: compiling a submission correctly, tracking a review clock, drafting a response that satisfies a specific agency question. The path to a good outcome is usually clear once the technical requirements are understood. Senior roles look different. A regulatory affairs director is rarely asked to execute a known task - they are asked to help decide between two imperfect options, to tell a VP of R&D that a timeline the company has already announced publicly is not realistic, or to convince a commercial team that a labeling claim they are counting on will not survive review.
None of those conversations can be won on technical correctness alone. Being right about the regulation is necessary but not sufficient - the other people in the room need to be persuaded, not just informed, and that requires a different skill than mastering the regulation itself.
What Influence Looks Like in Practice
Influence in a regulatory affairs context is rarely dramatic. It shows up as the ability to translate a regulatory risk into terms a non-regulatory audience will act on - not "this violates 21 CFR 820" but "this choice adds four to six months to our timeline and a real chance of a rejection we cannot easily appeal." It shows up as credibility built before it is needed: a regulatory lead who has a track record of giving realistic, not reflexively conservative, guidance gets listened to differently than one who is known for saying no to everything. And it shows up as judgment about which battles matter - holding firm on requirements that genuinely protect the company or the patient, while finding workable middle ground on points where flexibility does not create real risk.
That last point is where a lot of regulatory professionals struggle. Treating every requirement as equally non-negotiable is a way of avoiding the harder, more valuable work of triage, and it is also what earns a regulatory function a reputation as an obstacle rather than a partner.
The Cost of Being "The Department That Says No"
Regulatory affairs has a well-earned reputation problem in some organizations: the function people route around rather than route through, because engaging early feels like inviting a delay. That reputation is corrosive to the actual mission of the role, because it pushes regulatory input later into a project, when changes are more expensive and options are narrower. Professionals who build genuine influence tend to reverse that pattern - other functions start bringing regulatory affairs in earlier, not because they are required to, but because past experience taught them that early input from this particular person saves time rather than costing it.
How Influence Differs From Authority
Regulatory affairs almost never has line authority over the functions it needs to align - R&D sets the product design, quality owns the management system, marketing owns the claims, and none of them report to regulatory affairs. That makes influence the only real lever available. It has to be earned through the quality and consistency of judgment over time, not asserted through a title. This is part of why influence skills matter more, not less, as a career advances: a regulatory affairs director has more at stake in cross-functional decisions and less formal power to control the outcome directly than a line manager in almost any other function at the same level.
Reading the Room Before Making the Case
Part of building influence is understanding that the same regulatory position needs to be framed differently depending on who is hearing it and what they are optimizing for. An engineering lead weighing a design change is usually most persuaded by a clear description of the technical risk and the evidence behind it. A commercial leader is usually more persuaded by the effect on timeline, cost, or competitive position. A finance stakeholder responds to a clear-eyed estimate of downside exposure if the regulatory risk is ignored. None of this means changing the underlying regulatory position to suit the audience - it means recognizing that the same conclusion can be delivered in several honest ways, and that choosing the right one is part of the job, not a compromise of it. Regulatory professionals who present the same rigid framing to every audience, regardless of what that audience actually needs to hear to act, tend to find their input gets acknowledged politely and then quietly deprioritized.
Building the Skill Deliberately
Influence is trainable, even for people who do not consider it a natural strength. A few things that reliably help: seeking out visibility in cross-functional forums rather than only communicating through written reports, since trust is built faster in conversation than in documents. Learning to write and speak in two registers - the detailed technical rationale a regulatory colleague needs, and the compressed, decision-focused summary an executive needs - rather than defaulting to one register for every audience. Studying negotiation and framing deliberately, the same way one would study a new regulation, rather than assuming it is purely a personality trait. Finding a mentor, inside or outside the organization, who is visibly good at this and paying attention to how they frame difficult regulatory positions in meetings. And practicing the habit of presenting regulatory input as a set of options with trade-offs rather than a single mandate, which invites collaboration instead of resistance.
What Erodes Influence Quickly
Influence is slow to build and fast to lose. A regulatory position that turns out to have been wrong, or overstated for effect, does more damage than a straightforward admission that a question needs more research. Inconsistency is another fast way to lose it: giving one team a firm answer and a similar team a softer one on a comparable question signals that regulatory guidance depends on who is asking rather than on the underlying risk, and colleagues notice that pattern quickly. The professionals who sustain influence over a career are usually the ones who are comfortable saying "I do not know yet, let me find out" rather than manufacturing false certainty to sound authoritative in the moment.
How Hiring Is Starting to Signal This
Job postings for senior regulatory affairs roles increasingly list stakeholder management, executive communication, and cross-functional leadership alongside the expected technical and regulatory qualifications. That is not incidental language. It reflects hiring managers who have watched technically excellent candidates struggle in senior roles because the job at that level is as much about moving people as it is about moving submissions, and who have started screening for the difference earlier in the hiring process rather than discovering it after someone is in the role.
A Common Misreading of Influence
It is easy to conflate influence with charisma or a naturally forceful personality, and that misreading discourages a lot of quieter, highly capable regulatory professionals from investing in the skill at all. In practice, some of the most influential regulatory affairs leaders are not the loudest people in the room. They are the ones whose input is consistently well-timed, well-framed, and grounded in judgment other people have learned to trust because it has proven reliable before. That kind of influence is built through preparation and pattern, not volume, which means it is available to introverted and extroverted professionals alike.
Influence Looks Different at Each Career Stage
For an individual contributor, influence often shows up in smaller moments: pushing back constructively in a project team meeting when a proposed design choice creates unnecessary regulatory exposure, or flagging a risk early enough that it reads as helpful foresight rather than a last-minute objection. For a manager, it extends to shaping how their own team's recommendations get framed before they reach senior stakeholders, and to protecting their team's credibility by making sure regulatory positions are consistent rather than shifting depending on who is asking. For a director or head of regulatory affairs, influence becomes close to the entire job description: shaping which regulatory strategy options even reach a leadership decision, and building enough trust with peers in R&D, quality, and commercial that regulatory input is sought before decisions are made rather than defended after the fact.
Conclusion
Technical expertise remains the entry price for a regulatory affairs career, and it never stops mattering. But the professionals who move furthest are the ones who treat influence as a skill to be built with the same discipline as any regulatory competency - practiced, studied, and refined - rather than as an innate trait some people simply have and others do not. For anyone aiming at a senior regulatory affairs role, that skill is worth investing in well before the job description starts demanding it.
