Marketing’s Invisible Tax – The Cost of Poor Ecosystem Design

Modern marketing organisations rarely suffer from a shortage of specialist capability. In fact, the opposite is often true. Over the last decade, clients have assembled increasingly sophisticated agency ecosystems spanning creative, media, social, CRM, production, commerce, influencer, data, technology and content operations. On paper, these ecosystems should deliver greater expertise, flexibility and innovation. Yet many clients describe a very different reality: duplication, friction, slow decision making, unclear accountability and work that feels harder to deliver than it should.

The instinctive response is to frame this as an agency problem. Agencies are accused of protecting territory, competing rather than collaborating, overcomplicating processes or failing to align around client priorities. While those behaviours certainly exist, clients often unintentionally create the conditions in which they emerge. Increasingly the issue is not the quality of the agencies themselves, but the partnership model itself and how the internal client operating model interacts and complements the external agency operating model.

The real issue: underinvesting in ecosystem management

Many organisations have invested heavily in agency capability while underinvesting in ecosystem management capability. That distinction matters.

High performing agency ecosystems don’t emerge organically. They are designed and invested in. They depend on clearly defined roles, decision rights, workflows, governance structures, KPIs and escalation paths. They require active orchestration and incentivisation. Without those foundations, even highly capable partners will default toward self-preservation and tactical optimisation. Creative agencies optimise for brand expression. Media agencies optimise for performance metrics. Production partners optimise for throughput and efficiency. Each objective may be individually sound while collectively they can quickly conflict with each other.

Complexity has outgrown governance

The challenge has intensified due to marketing itself becoming structurally more complex. The proliferation of channels, content demands, retail media, AI-enabled production and real-time optimisation has dramatically increased the number of interdependencies inside the ecosystem. A campaign is no longer a sequence of linear handovers. It is a network of simultaneous activities involving multiple partners, platforms, technologies and approval processes. Yet despite this, governance models have not kept up with this rise in complexity.

The invisible tax on marketing organisations

The result is an invisible tax on marketing organisations with excessive time spent coordinating rather than creating, correcting not complementing.

• Agencies duplicate strategic work since briefing and upstream alignment is weak
• Approval layers multiply because accountability is unclear
• Creativity diluted due to ‘decision by committee’
• Relationships sour due to ambiguity around the client/agency value exchange
• Schedules slip due to dependencies not being mapped properly

This ‘tax’ is very measurable when considering the financial impact the following creates. We estimate this as a 10% loading on non-working investments:

• Coordination overhead
• Duplicated activities
• Delayed decision-making
• Fragmented workflows
• Disconnected measurement

What better ecosystem design requires

Addressing that tax requires more than stronger agency relationships or incremental process improvement. It requires a clearer operational model for how the ecosystem itself is designed, governed and enabled to perform.

Fundamentally, it is the system that creates tension, not necessary a function of agency underperformance.

The strongest ecosystems usually feel simpler, faster and more collaborative. Clarity reduces friction, partnership creates safety. When agencies understand how decisions get made, where responsibilities begin and end, how success will be measured and how conflicts will be resolved, collaboration becomes easier. Good governance (not rigid bureaucracy) should enable speed rather than slow it down.

“Agency management” needs a rethink. Relationship stewardship (chemistry, responsiveness, performance management) are table stakes with modern ecosystems now demanding an additional layer of operational leadership.

This means own the system itself. This means defining how strategy flows into execution, briefs are structured, data is shared, how handoffs work, production is governed, how agencies contribute without duplicating effort and how KPIs align across the ecosystem rather than incentivising siloed behaviours.

It means recognising that process design is not administrative overhead. It is a core driver of effectiveness.

Evidence that coherence improves outcomes

There is growing evidence that stronger organisational coherence improves marketing outcomes. Research from System1 and ISBA on “compound creativity” highlights the long-term value generated through consistency, distinctive assets and sustained creative platforms.

Achieving that consistency across fragmented ecosystems requires coordination and governance, not just creative talent. Meanwhile CreativeX has repeatedly highlighted the scale of asset waste within modern content supply chains, with significant volumes of produced content never ultimately used. These inefficiencies are rarely caused by one bad actor. More often they emerge from poorly connected systems and unclear operating models.

The opportunity for clients is therefore not simply to demand better collaboration from agencies. It is to create the conditions within which collaboration can realistically succeed.

From brand manager to ecosystem orchestrator

This requires a shift in mindset. Agencies should not be viewed as isolated suppliers operating independently around the edge of the organisation. They are participants and partners within a broader delivery ecosystem that the client ultimately owns. The organisations that manage this best increasingly behave less like traditional brand managers and more like ecosystem orchestrators.

In a landscape defined by complexity, the competitive advantage may no longer come solely from having the best individual agencies. It may come from being the client best equipped organisationally, and most capable of helping those agencies work together effectively.

How mediasense helps organisations respond

mediasense works with the world’s leading marketing organisations to assess where organisational complexity, fragmented governance and inefficient workflows may be limiting effectiveness across their marketing ecosystem. Importantly, we help organisations quantify the commercial impact of accumulated complexity, duplicated effort, coordination overhead and delayed execution.
Depending on whether marketing organisations are looking to re-ignite, re-model or re-imagine the way they are organised and work with agencies, we combine deep expertise with an unparalleled perspective into how leading brand and agency organisations operate together to unlock productivity and growth from their partnerships.
The result is not simply a more efficient operating model, but a marketing organisation better able to focus its time, energy and investment on the activities that most directly drive growth, effectiveness and return from its exiting ecosystem investment.

How to get started

mediasense offer a proprietary diagnostic to help marketing organisations identify and optimise this ‘invisible tax.’ Typically, it is a 10-12 week programme, with input (via interview and survey) from a cross section of stakeholders across client and agency organisations. Alongside supplementary desk research and our extensive client and agency database, we help to both qualify and quantify the ‘tax’ and build roadmaps for how marketing organisations can build more fit-for-future-purpose marketing ecosystems.
