The service function model of marketing produces competent execution. It does not produce strategic competitive advantage. The organisations that win on marketing operate with the ownership, iteration discipline, and customer centricity of a product company.
The Service Function Mindset and Why It Limits Marketing’s Potential
The service function model of marketing has deep roots in Australian organisations. In this model, the marketing function exists to serve the commercial objectives set elsewhere — by the CEO, the sales leadership, or the business unit heads — through the production of materials, campaigns, and communications. Marketing’s value is measured by its responsiveness, its output volume, and its ability to deliver on briefs that arrive from other parts of the organisation. The function is a support function: capable, professional, and consistently subordinate.
The service function model produces competent marketing execution. It does not produce strategic marketing leadership. When marketing is structurally positioned as a service to other functions, it cannot operate as a source of competitive advantage. It cannot accumulate the deep understanding of customer behaviour, competitive dynamics, and market trajectory that strategic marketing requires, because the cadence of service delivery does not leave room for the sustained analytical investment that understanding demands. It cannot develop the organisational influence needed to shape the commercial decisions that determine what marketing is being asked to achieve.
The organisations that have broken out of the service function model are those that have deliberately repositioned marketing — structurally and culturally — as a product function. In this model, marketing does not respond to briefs. It owns domains. It manages a portfolio of customer relationships, brand assets, and market positions with the same deliberateness and long-term orientation that a product company applies to its product development roadmap. The distinction is not semantic. It produces fundamentally different operating rhythms, capability requirements, and commercial outcomes.
What Operating Like a Product Company Actually Means
The product company analogy in marketing is most usefully understood through a set of operating principles that distinguish product-oriented marketing functions from service-oriented ones. The first is ownership versus execution: product marketing functions own outcomes, not activities. They are accountable for the commercial performance of the brands, segments, and channels they manage, not for the delivery of campaign assets or the fulfilment of internal briefs.
The shift from service function to product function is not about structure or headcount. It is about where accountability for commercial outcomes lives and whether marketing is empowered to own those outcomes completely.
The second principle is iteration over perfection. Product companies operate on short feedback loops — they release, measure, learn, and adapt quickly, treating each launch as a test of a hypothesis rather than the delivery of a finished product. The most effective marketing functions have adopted the same orientation. They run experiments, measure outcomes rigorously, and apply learnings systematically to the next iteration rather than managing each campaign as a standalone event with its own budget and timeline.
The third principle is customer centricity as a structural discipline, not a cultural aspiration. Product companies build their development processes around deep customer understanding — qualitative insight, quantitative validation, regular user testing, and continuous feedback loops that ensure the product remains aligned with evolving customer needs. Marketing functions that operate with the same structural commitment to customer insight produce strategies, creative work, and channel decisions of a consistently higher calibre than those that treat customer research as an occasional input rather than a continuous discipline.
The Capability Requirements of the Product Model
Operating marketing as a product function rather than a service function requires a different set of capabilities — in the leadership of the function, in the skills it employs, and in the infrastructure that supports it. The capability requirements are more demanding, which is part of why the transition is difficult and why many organisations that aspire to the product model end up reverting to service function behaviours when the operational pressure is high.
Making the Transition
The transition from service function to product function is a leadership project as much as an organisational design project. It requires the CMO to redefine the function’s relationship with the rest of the organisation — moving from responsive to proactive, from output-accountable to outcome-accountable, from executing briefs to setting agendas. This transition is uncomfortable for functions that have built their credibility through responsiveness and execution quality, and it typically encounters resistance from the organisational stakeholders who have benefited from the service model.
The transition also requires CEO support. A CMO who attempts to reposition the marketing function as a product-oriented strategic driver without active CEO backing will face structural and political obstacles that are difficult to overcome. The CEO’s visible endorsement of the new model — in the way marketing is represented in executive conversations, in the metrics that are used to evaluate marketing performance, and in the resources allocated to marketing’s capability development — is a necessary condition for the transition to succeed.
The organisations that have made this transition successfully tend to have done so incrementally — building credibility for the new model through the performance of specific product-oriented initiatives before attempting to apply it to the full function. This incremental approach allows the marketing function to demonstrate the commercial value of the product model, build the capabilities it requires, and earn the organisational trust needed to expand its scope without triggering the political resistance that a wholesale transformation typically produces.
The Strategic Board Implication
For boards and executive teams, the service versus product function question in marketing is ultimately a question about how the organisation intends to compete. If marketing is a service function, the organisation is competing primarily on its ability to execute campaigns efficiently and respond quickly to commercial requirements. If marketing is a product function, the organisation is competing on its deep understanding of customers, its ability to build enduring brand positions, and its capacity to iterate toward commercial effectiveness faster than its competitors.
The second model is the more demanding and the more differentiated. It requires a level of investment in marketing capability, leadership, and infrastructure that is significantly higher than the service model demands. But for organisations competing in markets where brand differentiation and customer relationships are primary sources of competitive advantage, the return on that investment is commensurately higher. The board’s responsibility is to ensure that the strategic aspiration and the operating model are aligned — and that the organisation is not expecting product function outcomes from a service function design.
