Influencing Without Authority: The PMM Superpower

Product wanted to launch in two weeks. I knew sales wasn't ready—they hadn't been trained, battle cards weren't done, and messaging was still being debated. If we launched on Product's timeline, it would fail.

But I had no authority to delay the launch. I didn't report to the VP of Product. I couldn't force sales training to happen faster. I couldn't demand Product wait.

All I could do was influence. And I had about 48 hours to figure out how.

This is the PMM paradox: You're accountable for launch success, win rates, and positioning effectiveness, but you have no direct authority over the teams that determine those outcomes. Product controls what gets built and when. Sales controls what gets sold and how. Marketing controls campaigns and messaging execution.

Your job is to align all of them toward a common strategy. And you have to do it without being anyone's boss.

Most PMMs fail at this because they either try to force compliance ("the charter says I own this") or they give up and just execute whatever others decide. Neither works.

The PMMs who succeed have learned to influence without authority. That's not a soft skill—it's the core PMM competency. Everything else is secondary.

Why Authority Doesn't Work in PMM

Early in my career, I thought the solution to cross-functional alignment was getting more authority. If I just had decision rights over launches, if my boss had more power, if the charter was clearer... then people would listen.

I was wrong.

I've worked at companies where PMM reported to the CEO and had explicit authority over launches. Guess what? Product still pushed back on delays. Sales still resisted new messaging. Marketing still wanted to do things their way.

Authority without buy-in just creates resentment and passive resistance.

People find ways to undermine decisions they don't agree with. Product schedules the launch anyway and blames PMM when it fails. Sales uses old messaging because they don't believe the new positioning. Marketing runs campaigns that contradict PMM strategy because they weren't truly aligned.

The PMMs I've seen succeed aren't the ones with the most authority. They're the ones who know how to build alignment so people want to execute the strategy, not because they have to, but because they believe it's the right call.

That requires influence, not authority.

The Three Influence Strategies That Actually Work

Most advice on influence is vague: "Build relationships." "Earn trust." "Communicate clearly." All true, but useless without specific tactics.

Here are the three influence strategies I've used to drive alignment on launches, positioning changes, competitive programs, and GTM strategy—all without formal authority.

Strategy 1: Make other people's goals easier to achieve

The mistake most PMMs make is trying to convince people that PMM's goals are important. They pitch the value of good positioning, the importance of competitive intelligence, the impact of sales enablement.

Nobody cares about your goals. They care about their goals.

Product cares about shipping features that customers adopt. Sales cares about hitting quota. Marketing cares about pipeline generation. CS cares about retention.

You influence them by showing how PMM work helps them hit their metrics.

When I wanted Product to delay a launch for sales training, I didn't say: "We need to delay because PMM best practices require 2 weeks of enablement."

I said: "If we launch Monday, sales won't know how to demo this. Based on our last rushed launch, that means 40% lower product adoption in the first 60 days. Delaying one week for training means your adoption targets are far more likely to hit."

Product delayed the launch. Not because they cared about enablement. Because I showed how enablement helped them hit their adoption goals.

When I wanted Sales to use new messaging, I didn't pitch "brand consistency" or "strategic positioning."

I showed them data: "Reps using this new messaging framework close deals 18% faster. Here's why: It addresses the top three objections we're seeing in competitive deals. We tested it with 10 top performers and they're already seeing better outcomes."

Sales adopted the new messaging. Not because I had authority to make them. Because I demonstrated it would help them hit quota.

The pattern: Don't pitch PMM priorities. Show how PMM work helps others achieve their priorities.

Frame every recommendation in terms of their goals:

• To Product: "This improves adoption, retention, and product-market fit"
• To Sales: "This increases win rates, shortens sales cycles, and grows deal sizes"
• To Marketing: "This drives more qualified pipeline and improves campaign conversion"
• To CS: "This reduces churn, increases expansion, and makes renewals easier"

When you're helping them win, they want to work with you.

Strategy 2: Use data to create undeniable conclusions

Opinions are debatable. Data is harder to argue with.

When I wanted to change our competitive positioning, the VP of Marketing disagreed. She thought our current positioning was fine. If it was her opinion vs. my opinion, she'd win (higher title, more authority).

So I didn't make it about opinions. I made it about data.

I analyzed 100 competitive deals. I found that:

• When sales led with our current positioning, win rate was 28%
• When sales led with the positioning I was proposing, win rate was 52%
• The difference was worth $6M annually

I presented this data to the VP of Marketing. She couldn't argue with the numbers. We changed the positioning.

Data doesn't just inform decisions—it removes the ability to ignore problems.

When Marketing wanted to run a campaign I thought was off-strategy, I didn't argue about strategy. I shared data from customer research showing that the campaign message wouldn't resonate with our ICP. Marketing adjusted the campaign.

When Product wanted to deprioritize a feature I thought was critical for competitive wins, I didn't argue about priorities. I showed win/loss data proving we lost 40% of deals specifically because we lacked that feature. Product moved it up the roadmap.

The best data for influence comes from:

• Win/loss analysis (why we win and lose deals)
• Customer research (what customers actually say, not what we assume)
• Sales conversation intelligence (what messaging actually works in real calls)
• Competitive intelligence (how competitors position against us)
• Usage data (what customers actually do vs. what we think they do)

Track this data continuously. When you need to influence a decision, you'll have the evidence ready.

Strategy 3: Build coalitions before you need them

The PMMs who fail at influence try to build alignment during the decision-making process. The PMMs who succeed build alignment long before decisions need to be made.

I learned this when I wanted to change our pricing structure. If I'd proposed the change in a pricing meeting with the CFO, VP Product, and CRO, they would have debated for weeks and probably rejected it.

Instead, I built coalition beforehand:

Week 1: Talked to the CRO. Shared data showing our pricing was losing enterprise deals. Got his buy-in that pricing was a problem worth solving.

Week 2: Talked to the VP Product. Shared the same data, plus customer feedback on pricing. Got his agreement that we should explore options.

Week 3: Talked to the CFO. Shared revenue modeling showing the upside of pricing changes. Got his acknowledgment that the numbers were worth exploring.

Week 4: Proposed pricing changes in a meeting with all three executives. I didn't have to convince anyone—they'd already agreed individually. The meeting was just formalizing consensus I'd already built.

Building coalitions before decisions means:

• You identify who has influence over the decision
• You meet with them individually to understand their concerns
• You address their concerns and get their buy-in before the group decision
• By the time you present formally, you've already aligned the key stakeholders

This sounds political, and it is. But it's also effective.

The alternative is presenting a recommendation to a room of skeptics and hoping to convince everyone at once. That rarely works when you lack formal authority.

The Influence Mistakes That Undermine PMMs

I've watched brilliant PMMs fail at influence because they made predictable mistakes:

Mistake 1: Leading with process instead of outcomes

Bad: "Per the launch checklist, we need two weeks of sales training before launch."

Good: "Sales training ensures reps can demo effectively, which drives 30% higher product adoption. Without it, our launch adoption targets are at risk."

Executives don't care about process. They care about outcomes. Frame your asks in terms of business impact, not procedural correctness.

Mistake 2: Fighting battles you don't need to win

I used to push back on everything I disagreed with. Product wanted to use different messaging than PMM recommended? I fought it. Marketing wanted to run a campaign I thought was off-brand? I argued.

I won some battles and lost credibility. Because when you fight everything, people stop listening.

Now I pick my battles carefully. I let small disagreements go and save my influence for decisions that truly matter. When I push back now, people listen because they know I only fight for things that significantly impact outcomes.

Mistake 3: Not giving people a way to save face

When someone makes a bad decision, pointing out that it was a bad decision doesn't make them want to change it. It makes them defensive.

Instead of: "That launch strategy was a failure because we didn't train sales."

Try: "The launch results weren't what we hoped. I analyzed why and found that sales training has 3x impact on launch adoption. For the next launch, I recommend we build in two weeks for training. Here's the ROI."

Same message, but the second version gives them a path forward without dwelling on past mistakes.

When Influence Doesn't Work

Sometimes, no amount of influence works. The stakeholder has already made up their mind. They don't care about data. They're not interested in coalition-building.

When that happens, you have three options:

Option 1: Escalate to a decision-maker

If your influence isn't working with a peer, escalate to someone with authority to make the call.

"Product and PMM disagree on launch timing. I've shared data on why delaying improves outcomes, but Product wants to proceed. Can we get alignment from the CMO and VP Product on the right path forward?"

Now it's not your influence vs. their resistance. It's an executive decision based on the data you've presented.

Option 2: Let them fail (and document why)

Sometimes the best influence is letting someone make a mistake and learning from it.

If Product insists on launching without sales training despite your recommendation, document your concerns, share the projected impact, and let them proceed.

When the launch underperforms, you have data proving why. Next launch, your influence will be stronger.

The risk: You're accountable for launch success even if you didn't agree with the strategy. Weigh whether letting them fail is worth the career risk.

Option 3: Align within your control and let go of the rest

You can't control everything. Sometimes you have to accept that Product will launch on their timeline, Sales will use their preferred messaging, and Marketing will run campaigns you don't love.

Focus your influence where it matters most and let go of the rest. Perfect alignment across all functions is impossible. Good enough alignment that moves the business forward is achievable.

The Uncomfortable Truth About Influence

Most PMMs think influence is about being persuasive. It's not.

Influence is about making it easier for people to say yes than to say no.

When you frame recommendations in terms of their goals, you make it easy to say yes (this helps me hit my targets).

When you bring data that makes the problem undeniable, you make it hard to say no (ignoring this problem creates risk).

When you build coalitions beforehand, you remove the obstacles to saying yes (everyone else already agrees, why would I disagree?).

That's not manipulation—it's understanding human behavior and organizational dynamics. People say yes to things that help them win and that others already support. People say no to things that create work or conflict.

The PMMs who influence effectively aren't the ones with the best arguments. They're the ones who remove friction from saying yes and create friction around saying no.

That requires empathy (understand what others care about), data (make problems undeniable), relationships (build coalitions), and strategy (pick your battles).

You don't need authority to do any of that. You just need to be deliberate about how you influence.

Start framing recommendations in terms of others' goals. Start building coalitions before decisions need to be made. Start using data to make problems undeniable.

Do that consistently for six months and watch how much more alignment you get without any formal authority changing.

Or keep trying to influence through good arguments and hoping people listen. Wonder why cross-functional alignment is so hard.

Your choice.
