Embarking on a new journey as a Medical Science Liaison (MSL) is both exciting and challenging. The role is pivotal in the pharmaceutical industry, bridging the gap between scientific research and practical healthcare solutions. To help you navigate this journey, let’s layout a strategic plan for your first 30, 60, and 90 days as an MSL.

Lay the Foundation

Your initial month as an MSL is all about learning and understanding. This period is filled with administrative tasks, research, and onboarding processes. It’s essential to familiarize yourself with the disease state and the product you’ll be working with.

Dive deep into the scientific literature, understand the disease’s pathology, and get a firm grasp on your product’s mechanism of action and all preclinical and clinical data. This foundational knowledge will be the bedrock upon which you build your future interactions with healthcare professionals and key opinion leaders (KOLs).

Identify Key Players

The second month is about identifying and understanding the key players in your field. This includes KOLs and significant institutions. Many companies provide a list of KOLs, but if they don’t, take the initiative to gather this information independently.

Start to understand the key national and regional meetings that are relevant to your therapeutic area. These meetings are often where the latest research is presented and where you can network with leading experts in the field.

Execute Strategy

The last 30 days of your initial quarter as an MSL is about putting your plan into action. By now, you should be ready to engage with KOLs, institutions, and conferences. The aim is to execute the company’s strategy and bring value to both the KOLs and the organization through clinical insights.

Remember, your role as an MSL is not just about disseminating information but also about gathering insights. Your interactions with KOLs can provide valuable feedback that can influence your company’s strategy and product development.

Additional Considerations

Throughout this 90-day plan, there are a few additional considerations to keep in mind:

Company Culture and Strategy: Understanding the company’s culture and strategy is crucial. This understanding will guide your interactions both within and outside the company.

Engagement: The essence of being an MSL is engagement. Whether it’s with KOLs, colleagues, or other stakeholders, effective communication and relationship-building are key.

Insights: Always remember that one of your primary roles as an MSL is to bring insights back to the company. These insights, gleaned from your interactions with KOLs and other healthcare professionals, can provide invaluable information that can shape the company’s strategy.


The first 90 days as an MSL are about learning, understanding, identifying key players, and executing strategy. With the right approach and mindset, you can make a significant impact in your role as an MSL and contribute to advancing healthcare solutions.
