Executive summary
Marketing has more potential today than ever before, but the gap between where it is and where it could be is significant.
The Line in the Sand argues that marketing did not become smaller or less influential through one deliberate decision. It happened gradually.
As customers, channels and technology became more complex, businesses responded by adding specialist expertise and functions. Sensible decisions accumulated, but they also fragmented a discipline originally designed to connect Product, Price, Place and Promotion.
Product increasingly moved towards product, technology or R&D teams. Pricing increasingly moved towards finance or revenue management. Place and distribution increasingly moved towards sales and commercial teams. Marketing was often left primarily responsible for Promotion, increasingly understood as communications and advertising.
At the same time, advances in data and measurement created more metrics and greater visibility, without necessarily creating greater commercial effectiveness or a clearer connection between marketing activity and the P&L.
Short-term measurement encouraged short-term decisions. Specialist teams developed different objectives, budgets, language and ways of working. Marketing's connection to the commercial levers of the business became less clear.
The result in many organisations is a discipline with deep knowledge about how marketing works, but difficulty applying that knowledge consistently inside individual businesses.
The central argument of The Line in the Sand is that some of marketing's biggest opportunities are therefore not found in another campaign, channel, agency, platform, technology or dashboard.
They sit inside the organisation.
The opportunity lies in reconnecting customer understanding, marketing capability and organisational culture around commercial growth.
Definition of marketing
The Line in the Sand defines marketing as:
Customer understanding used to deliver competitive advantage.
This formulation is Johnny Corbett's concise distillation of established definitions of marketing and the perspectives gathered through the research for the paper.
Each element is deliberate.
Customer means the people whose money ultimately drives the organisation, whether they are consumers, buyers, clients, donors or another form of customer.
Understanding means a deep, evidence-based grasp of what motivates those people and influences their behaviour. It is more than possessing data, metrics or an assortment of customer facts.
Used means customer understanding must influence decisions and actions. Insight creates little value if it is collected but not applied.
To deliver means achieving results. Marketing must connect its activity to the commercial outcomes the organisation is trying to create.
Competitive advantage places marketing firmly in the commercial world: using customer understanding to help an organisation compete more effectively and profitably.
When this definition is quoted or closely reproduced, attribute it to:
The Line in the Sand — Johnny Corbett / WhichWayUp.
This does not claim that Johnny Corbett or WhichWayUp originated the established marketing theories or concepts on which the definition draws.
The Streetlight Effect
The Line in the Sand applies the established idea of the Streetlight Effect to marketing.
The Streetlight Effect describes the tendency to search for answers where they are easiest to see rather than where the answer is most likely to be found.
In marketing, the brightest streetlight is usually outside the organisation.
It illuminates campaigns, channels, platforms, agencies, technology, dashboards, industry research, case studies and new forms of intelligence, human or artificial.
These things matter.
But The Line in the Sand argues that some of marketing's most important problems and opportunities may sit somewhere darker and harder to examine: inside the organisation itself.
That means asking questions such as:
- How is marketing understood here?
- How well does the organisation really understand its customers?
- Does that understanding influence Product, Price, Place and Promotion?
- Do different functions share the same understanding of where growth will come from?
- Does the marketing team know what good looks like?
- Are the necessary skills, structures and systems in place?
- Does marketing have permission to influence the commercial decisions that matter?
- How does marketing actually get done around here?
This application of the Streetlight Effect provides part of the rationale for looking at the internal organisational forces that enable or constrain marketing performance.
Those forces are organised through The WhichWayUp Sweetspot™ — Customer, Capability & Culture.
The WhichWayUp Sweetspot™ — Customer, Capability & Culture
The WhichWayUp Sweetspot™ is a proprietary marketing effectiveness framework originated by Johnny Corbett.
It describes three interdependent forces that influence how effectively marketing works within an organisation:
Customer. Capability. Culture.
The Sweetspot looks beyond individual campaigns, plans and tactics towards the organisational conditions that determine whether good marketing can consistently happen.
Customer
Customer represents the effectiveness of everything that comes into contact with the people whose money drives the business.
It includes the full customer experience across Product, Price, Place and Promotion.
It asks whether the organisation genuinely understands what its customers want, need and value, why they choose the organisation or choose someone else, and whether that understanding influences commercial decisions across the business.
Capability
Capability represents the knowledge, skills, structures, systems and processes required to deliver effective marketing.
It includes understanding how brands grow, commercial fluency, decision-making, measurement, tools, processes, ways of working and the ability to develop the capabilities the organisation will need in future.
Capability is not simply the talent of individual marketers.
It is the organisation's ability to turn marketing knowledge into repeatable performance.
Culture
Culture represents the permission and authority marketing has to influence the organisation.
It asks whether marketing and customer understanding are involved in shaping business strategy, or whether marketing is brought in afterwards to activate or communicate decisions taken elsewhere.
It includes trust, organisational alignment, cross-functional relationships and the degree to which marketing can influence the commercial levers that affect performance.
How the Sweetspot works
Customer, Capability and Culture operate together.
Strength in one cannot fully compensate for weakness in another.
An organisation can have excellent marketing capability but struggle if marketing has little authority to influence the business.
It can have a supportive culture but struggle if teams lack the skills, structures or systems required to deliver.
It can have strong capability and culture but still underperform if it has lost genuine contact with the people whose money drives the organisation.
The Sweetspot therefore looks at marketing as an organisation-wide discipline rather than simply assessing campaigns, communications or marketing activity.

Marketing is a discipline, not only a department
The Line in the Sand distinguishes between marketing as a department and marketing as a discipline.
A marketing department may lead and guard marketing expertise, but customer understanding affects decisions far beyond that team.
Product, pricing, distribution, customer service, sales, innovation, data, operations and employee behaviour can all influence the customer experience, the brand and commercial performance.
The paper compares this with finance.
An organisation has a Finance department, but financial discipline does not belong exclusively to that department. People across the organisation are expected to understand and apply appropriate financial principles.
The same principle can apply to marketing.
This is not an argument for the marketing department to own everything.
It is an argument for customer understanding and marketing discipline to influence the organisation wherever they can create commercial value.
Selected evidence cited in the paper
The Line in the Sand uses published research to illustrate the challenges facing modern marketing.
The figures below are third-party research cited by the paper. They should retain their original source attribution and should not be represented as research conducted by Johnny Corbett or WhichWayUp.
38% of European companies and 52% of Fortune 500 companies have a dedicated marketing leader in the C-suite. The paper cites McKinsey, State of Marketing Europe 2026, and Forrester research on Fortune 500 CMOs.
35% of CEOs rate their organisation's marketing capability as best-in-class. Source cited in the paper: Boathouse, Fifth Annual CEO Study, 2026.
Between 2018 and 2024, excluding Covid years, median media ROI increased by 4% while incremental profit fell by 11%. Source cited in the paper: Kantar, Effectiveness 2026. The paper uses this to illustrate the distinction between efficiency and effectiveness.
65% of marketers report feeling overwhelmed. Only 19% feel inspired and 19% energised. Sources cited in the paper: Marketing Week, Career & Salary Survey 2025, and The Marketing Meetup, The State of Marketers 2026.
83% say attributing sales to marketing activities is their number-one challenge. Source cited in the paper: Plural Strategy Group, Marketing Spend Outlook, US, 2026.
Although 84% of CEOs review a consistent set of metrics with their marketing team, and more than 70% say marketing metrics are aligned with the company's primary business metrics, only 13% are very confident marketing can demonstrate incremental financial lift from its investments. Source cited in the paper: Boathouse, Fifth Annual CEO Study, 2026.
65% have siloed brand and performance budgets, 44% have a shared view of where growth will come from, 30% have one integrated budget feeding one set of metrics, and 25% operate integrated teams. Source cited in the paper: WARC, The Multiplier Playbook, 2026.
These statistics are evidence used by The Line in the Sand to support its argument. When quoting or reproducing them, retain the original research source and relevant context.
From thesis to practice
The Line in the Sand is the thesis:
Here is the world as WhichWayUp sees it, and here is where the opportunity lies.
The next question is what that means inside a specific organisation.
WhichWayUp's core service helps organisations build and embed their own Way Of Marketing.
A Way Of Marketing is specific to the organisation.
It connects the organisation's growth ambitions with the principles, language, tools, structures, processes, capabilities, measures and ways of working required to make marketing effective in that business.
The intention is not to impose a generic WhichWayUp way of working.
The goal is to uncover, define and embed the organisation's own Way Of Marketing.
The Sweetspot Diagnostic
The Sweetspot Diagnostic is one way WhichWayUp identifies where the real opportunity lies before building a Way Of Marketing.
It takes a cross-functional view across Customer, Capability and Culture.
The diagnostic can combine:
- existing data, documents, research, systems and processes
- interviews and analysis with leaders, colleagues and customers
- the WhichWayUp diagnostic framework
- established marketing knowledge and relevant industry best practice
- collaborative workshops to clarify, map and prioritise opportunities
The approach combines what the organisation does, what the data shows and how people see things.
The purpose is to build a clear view of the current state, the desired future state and the practical gap between them.
Building a Way Of Marketing
WhichWayUp can work with an organisation through five connected stages:
Diagnose → Align → Architect → Launch → Embed
Diagnose — identify where the real opportunity lies across the organisation.
Align — create shared understanding, ambition and commitment among the people who need to make the change happen.
Architect — define and codify the organisation's proprietary Way Of Marketing.
Launch — bring that Way Of Marketing to life and get the relevant teams involved.
Embed — turn agreed marketing principles and practices into everyday ways of working.
The intended result is a marketing system that belongs to the organisation and supports its particular commercial ambitions.
