What to Read Next
The next wave of successful CMOs will be defined by their ability to bring out the best in their technology.
They know how to turn fragmented data into strategy, AI into executional speed and marketing investment into measurable business value. They can step into a boardroom and explain growth in the same language as finance, and keep teams of analytical minds, strategists and creatives motivated and aligned.
To reach that level, senior marketers are learning to quantify brand impact, model budget trade-offs, build cross-functional alignment and prove ROI before they’re asked.
Here are the 10 skills essential to today’s CMOs;
1. Data and analytics mastery
Modern CMOs build systems that make data reliable enough to drive sustainable growth, understanding what teams need to build a robust, scalable data infrastructure.
How to build this skill:
- Establish clear ownership across analytics, finance and marketing operations
- Prioritise naming, tracking and definitions before adding new tools
- Reconcile core datasets, align reporting standards and use forecasting models to test scenarios before committing budget
The CMO’s role is to design the system and interpret its output, ensuring that every dollar can be traced to growth, turning analytics from reporting into leverage.
2. AI and automation adoption
AI now powers marketing pace, stemming from AI’s ability to analyse billions of signals faster than any analyst, and precision, automating those insights into daily execution. The CMOs moving fastest treat AI as infrastructure that amplifies human intelligence rather than replacing it.
How to build this skill:
- Automate execution by using AI to handle repetitive analysis and campaign optimisation so teams can focus on judgment
- Focus on intent so that when marketing uses AI to make work more creative and relevant to growth, this, in turn, will drive profitability
AI adoption is now a leadership skill, and it shows that you can build systems that think with you, not for you.
3. Budget justification
According to The CMO Survey, 63% of marketers face growing pressure from CFOs to prove
marketing’s financial impact. Budget justification is the skill that closes that gap, linking spend to business outcomes with the same rigour that finance applies to investments. Strong CMOs align on definitions of revenue, payback and margin before presenting spend.
How to build this skill:
- Co-author performance frameworks with finance
- Model different investment scenarios and forecast how changes in spending affect growth
- Reconcile forecasts with actuals to refine trust and predictability
The CMO who speaks in the same terms as finance builds credibility for marketing.
4. CX leadership
High-performing CMOs design every interaction around customer experience to find measurable business outcomes and adapt experiences to reduce friction and strengthen loyalty. Forrester’s 2024 US Customer Experience Index found that only 3% of companies are truly customer-obsessed.
How to build this skill:
- Audit the customer journey to find where expectations break down
- Set shared CX metrics across teams so accountability extends beyond marketing
- Unite teams around shared metrics on a central dashboard so everyone works from a single, reliable view of performance
5. Team leadership
The best CMOs measure success by how capable their teams become. Team leadership means building an environment where people can decide, adapt and learn faster than the market changes.
Google’s long-term ‘Project Oxygen’ study, which they launched in 2008, found that teams with strong managers are up to 44% more productive and have lower turnover than those with weak leadership.
How to build this skill:
- Hire for range by balancing analytical, creative and operational strengths
- Turn development into practice by assigning stretch roles tied to measurable outcomes
- Create space for ownership by setting objectives
Behind every successful marketing campaign is a department that balances creativity with data discipline and strong leadership.
6. Cross-functional collaboration
Cross-functional collaboration is important for aligning finance, sales and product on the same numbers to make decisions. When CMOs bridge that gap, they create a unified view of business goals, of which marketing is an essential cog.
How to build this skill:
- Align planning cycles so marketing, finance and product build forecasts together
- Integrate financial and performance data into one view of ROI to create shared confidence across functions
- Hold quarterly joint reviews to refine assumptions and update shared models
7. Agility in uncertain markets
Volatility is constant as privacy laws evolve, platforms shift, and customer behaviour changes week to week. Uncertainty must be an operating context, so systems are designed to absorb emerging technologies and market trends early and adjust before they become expensive.
How to build this skill:
- Plan scenarios in advance so pivots are deliberate
- Review performance weekly and adapt based on leading indicators
- Rely on systems that refresh data daily, so decisions stay current and grounded in reality
- Give teams authority to adjust budgets within set guardrails so speed never sacrifices governance
8. Marketing measurement and attribution
Measurement is proof, and the CMOs who connect marketing data to business results encourage trust among CFOs.
How to build this skill:
- Unify spend, conversions and revenue across all platforms for consistent performance views
- Standardise naming conventions and currencies to remove mismatched reporting
- Combine short-term attribution with MMM or incrementality to understand both immediate and long-term effects
CMOs must have experience with a wide range of measurement techniques so they know how models combine to create holistic views of performance and make smarter spending decisions.
9. Agency–brand partnership skills
Agency partnerships succeed when trust is built on data rather than opinion. The modern CMO creates transparency between teams so every decision is grounded in the same facts and accountable to the same results.
How to build this skill:
- Set joint KPIs and shared business outcomes before campaigns begin
- Review performance together and turn data reviews into strategy sessions
- Reward collaboration by linking agency performance metrics to business results
Unified, reliable data is the foundation of an agency-brand partnership built on performance.
10. Tech stack fluency
Part of the CMO role involves being a systems thinker and having fluency in tech, knowing how cleanly data moves through a stack.
How to build this skill:
- Strip the stack to what drives clarity and speed
- Connect data, analytics and activation through governed, automated pipelines so every tool runs on trusted inputs
- Partner with IT to turn governance and security into enablers
When CMOs control how data flows, every decision gets sharper, and every system compounds insight.
All Successful CMOs Require Creativity
The CMOs leading the next era are multidimensional thinkers, blending data fluency with creativity, business judgment and people skills.
Data mastery anchors these abilities, turning instinct and creativity into impact. Reliable data turns insight into evidence and evidence into strategy. Creativity converts that strategy into results. Business acumen directs investments toward growth, and people skills align teams behind a shared mission.
Combining these skills will put you on the right track for success.
