Consider this fair warning, we’re about to say the one word that makes MSLs a little twitchy – sales. Coaching has long been recognized as a critical driver of sales performance. In most organizations, it is embedded into daily operations: managers coach representatives, ride‑a-longs are documented, and feedback is structured and measurable. Over time, these practices have matured into a core part of sales culture.

As sales coaching has evolved, however, another critical field role has often been overlooked, Medical Science Liaisons (MSLs).

MSLs are highly trained scientific experts who engage in complex, peer‑to‑peer clinical discussions with healthcare professionals. Their depth of expertise and autonomy can create the perception that coaching is less necessary for this role, especially given many MSLs come into the role as seasoned professionals (nurses, pharmacists, physician assistants, etc).

In reality, MSLs benefit from coaching just as much as sales teams, as they arguably have one of the most critical roles in their organization.

Why Coaching Has Historically Focused on Sales

Sales roles naturally lend themselves to structured coaching. Performance expectations are clear, activities are easy to track, and outcomes are closely tied to revenue. This clarity has driven long‑standing investment in coaching frameworks, manager enablement, and documentation processes.

Medical Affairs roles evolved differently. The emphasis has traditionally been on scientific credibility, independence, and trusted exchange. While these attributes are essential, they have also contributed to a less formal approach to coaching—one that often relies on individual experience rather than intentional development.

Why MSLs Are Different — but Still Need Coaching

MSLs are not sales representatives and coaching them should not resemble sales coaching. Their value lies in scientific depth, credibility, and the ability to facilitate unbiased exchange. But being different does not mean being exempt from development.

In practice, MSLs must navigate nuanced scientific discussions, adapt complex data for diverse stakeholders, generate meaningful insights, and represent the scientific voice of the organization with consistency and integrity. These responsibilities require more than knowledge alone.

Effective MSL coaching is not just about clinical acumen. It is about refining how scientific expertise is communicated, applied, and aligned with Medical Affairs objectives. Without structured coaching, even highly capable MSLs can develop inconsistent engagement approaches, miss opportunities to deepen scientific dialogue, or struggle to adapt as priorities and evidence evolve.

What Effective MSL Coaching Looks Like

Effective MSL coaching is intentional, role‑specific, and continuous. Rather than emphasizing activity metrics, it focuses on the quality and impact of scientific engagement.

At its core, strong MSL coaching reinforces both clinical and behavioral competencies, including:

  • Scientific storytelling and clarity of communication
  • Handling complex or challenging questions
  • Stakeholder engagement strategies
  • Insight generation and documentation
  • Compliance‑aligned scientific exchange

Timing matters as much as content. Coaching is most impactful when feedback is provided close to field interactions, allowing MSLs to reflect and adjust while experiences are still fresh. Ongoing feedback supports development far more effectively than infrequent, retrospective evaluations.

Where MSL Coaching Often Breaks Down

Although many organizations recognize the value of coaching MSLs, execution is often inconsistent. Feedback may be informal or undocumented, approaches can vary widely by manager or region, and visibility into development trends is limited.

When coaching insights are not connected to shared competency frameworks or learning resources, development becomes difficult to sustain. In these cases, coaching remains reactive and personal rather than intentional and scalable.

Creating Structure Without Compromising Scientific Autonomy

The challenge for Medical Affairs leaders is not whether MSLs should be coached, but how to introduce structure without undermining the scientific nature of the role.

Thoughtfully designed coaching approaches—facilitated by platforms such as iCoach—can create consistency, documentation, and visibility while still respecting MSL autonomy. When coaching is aligned with Medical Affairs competencies and priorities, it supports development without turning scientific engagement into a transactional process.

How to Measure Effective MSL Coaching

Measuring MSL coaching requires a different lens than sales performance. Traditional activity‑based metrics rarely capture the value of scientific engagement. Instead, effective measurement focuses on progression, consistency, and impact over time.

Key indicators include:

  • Observable improvement in core competencies such as scientific communication and stakeholder engagement
  • Greater consistency in how scientific narratives and key topics are discussed across teams
  • Higher‑quality insights captured and shared with the organization
  • Increased alignment between coaching, development plans, and training resources

Coaching Isn’t Just for Sales — It’s for Impact

MSLs play a critical role in shaping scientific dialogue and advancing patient care. Supporting them with intentional, well‑structured coaching helps ensure those interactions are consistent, effective, and aligned with organizational goals.

Organizations that take a deliberate approach to MSL coaching don’t just improve individual performance. They strengthen the Medical Affairs function as a whole, building a culture of continuous development that supports better scientific engagement and better outcomes.
