Marketing is one of the most consistently misunderstood functions in business. In organizations where it is well understood, it operates as the intelligence and architecture layer of commercial strategy — defining who the company sells to, how products are positioned, what messages reach which audiences, and how the commercial organization is equipped to execute. In organizations where it is poorly understood, it is reduced to event coordination, graphic design, and content production — activities that are visible and measurable in the short term but that represent a fraction of what a high-functioning marketing organization actually contributes.
The gap between these two versions of marketing is not primarily a talent gap. It is a structural and definitional gap: organizations that have not clearly defined what marketing is responsible for, and have not given it the authority and resources to execute those responsibilities, get a narrow version of marketing because that is all they have created the conditions for.
The Three Tiers of Marketing
Marketing in a mature life sciences or B2B technology organization operates across three tiers simultaneously, each with distinct responsibilities, outputs, and internal customers.
Product marketing is the tier closest to the product and the customer’s evaluation process. It is responsible for understanding the specific customer for each product, developing the value proposition, defining the competitive positioning, creating the proof architecture, and equipping the sales team with the tools and messages it needs to compete effectively. Product marketing is the translation layer between what the product does and what the customer needs to hear in order to consider, evaluate, and purchase it.
Global or portfolio marketing is the tier responsible for the company’s coherent story across its entire product portfolio and all the markets it serves. It pulls together the individual product narratives into a unified company identity, manages the brand architecture, and ensures that the company’s external presence is consistent and coherent.
Strategic marketing is the tier responsible for the market intelligence and analytical foundation on which both product and portfolio marketing depend. It tracks market trends, monitors competitive positioning, conducts customer research, and provides the evidence base that informs positioning decisions and commercial investment allocation.
What Marketing Is Not
Understanding what marketing does requires being equally clear about what it is not.
Marketing is not synonymous with advertising or promotion. Advertising and promotion are execution activities that marketing may direct and manage, but they represent the output layer of a strategic process, not the process itself.
Marketing is not a support function for sales. This framing — common in organizations where the commercial team is sales-led — misrepresents the relationship between the two functions. Marketing and sales are complementary halves of the commercial function: marketing defines the strategy, builds the infrastructure, and develops the market; sales executes the strategy, converts the opportunities, and generates the revenue.
Marketing is not a cost center. It is a revenue architecture function. The awareness it builds, the positioning it establishes, the leads it generates, and the sales enablement it provides are all inputs into revenue that are difficult to attribute in real time but are clearly visible in the commercial trajectory of companies that invest in marketing versus those that do not.
Marketing’s Role in Life Sciences
In life sciences and regulated markets, marketing carries responsibilities that go beyond what its equivalent in consumer or general B2B markets typically includes. The technical complexity of the products, the sophistication of the buyers, the regulatory constraints on claims, and the length of the commercial relationships all shape how marketing operates and what it produces.
Scientific credibility is a marketing output in life sciences. Application notes, clinical publications, regulatory submissions, and the presentations made at scientific conferences are all forms of market communication that build the brand’s credibility with its most important audiences.
The companies in life sciences that take the broadest and most strategic view of what marketing does consistently outperform those that take the narrowest view — not because marketing is more important than the other functions, but because marketing done well makes every other commercial function more effective.
