Why Most Product Roadmaps Are Fiction (And How to Fix Yours)

The Roadmap Ritual

Every quarter, product teams perform the same ritual:

1. Stakeholders demand visibility into "what's next"
2. Product team creates a beautiful roadmap
3. Everyone nods and feels productive
4. Three months later, 70% of it didn't ship
5. Repeat

The roadmap becomes a work of fiction—optimistic timelines, scope that shifts, priorities that change, dependencies nobody accounted for.

And yet, we keep making them. Because the alternative—admitting we don't know—feels worse than pretending we do.

Why Roadmaps Fail

Most roadmaps fail for the same reasons:

They're built on assumptions, not data

"This should take 2 weeks." Based on what? A guess. No validation, no prototyping, no actual understanding of complexity.

They treat estimates as commitments

An estimate is a guess with error bars. A commitment is a promise. Roadmaps confuse the two, and suddenly "probably Q2" becomes "definitely Q2" in stakeholders' minds.

They ignore dependencies

Feature A requires infrastructure work. Infrastructure requires platform upgrade. Platform upgrade is blocked waiting for vendor. None of this made it onto the roadmap.

They optimize for looking busy, not shipping value

20 items on a roadmap feels productive. But you're not going to ship 20 things in a quarter. You'll ship 3, poorly, because you were spread too thin.

They don't account for reality

Bugs. Customer escalations. Technical debt. Hiring. Onboarding. People taking vacation. Life.

None of this appears on the roadmap. But all of it eats capacity.

What a Realistic Roadmap Looks Like

A good roadmap isn't about predicting the future. It's about making better bets with imperfect information.

Here's how:

1. Start with outcomes, not features

Bad roadmap: "Build dashboard with real-time analytics" Good roadmap: "Give sales visibility into pipeline health so they can forecast accurately"

Features are guesses about how to achieve outcomes. Start with the outcome. The features can change.

2. Prioritize ruthlessly

Not "top 10 priorities." One priority. The thing that matters most this quarter.

Everything else is either:

• Supporting that priority
• Keeping the lights on (maintenance, bugs, tech debt)
• Deferred (we'll get to it later, maybe)

If everything is important, nothing is. Force the hard choices.

3. Size things honestly

Stop estimating in "ideal days" where nothing goes wrong. Estimate in actual capacity.

If you have 4 engineers and 12 weeks, you don't have 240 days of capacity. You have:

• 240 days total
• Minus 20% for meetings, email, interruptions = 192 days
• Minus 20% for bug fixes, tech debt, support = 154 days
• Minus 20% for things you didn't anticipate = 123 days

Now plan against 123 days. That's your real capacity.

4. Account for uncertainty

Don't plan like everything will go perfectly. Build in buffers:

• New feature in a familiar area: 1.5x the estimate
• New feature in an unfamiliar area: 2x the estimate
• Integration with third-party service: 3x the estimate
• Something "should be simple": 4x the estimate

The more uncertainty, the bigger the buffer.

5. Make dependencies visible

Before you commit to Feature X, identify what it requires:

• Infrastructure changes
• Third-party integrations
• Design resources
• QA time
• Vendor approvals
• Legal review

If any of those aren't locked down, your timeline is fiction.

6. Plan for disruption

In any given quarter:

• 10-20% of capacity will go to unplanned work (bugs, escalations)
• 10-15% of capacity will go to technical debt you can't avoid
• Someone will leave or take extended time off

Plan for this. Don't pretend you have 100% capacity for new features.

The Three-Tier Roadmap

Instead of one roadmap, build three:

Committed (this quarter)

What: The 1-3 things we're definitely shipping Confidence: 90%+ Detail: Fully scoped, validated, resourced

This is what you promise. Keep it small. Make sure you can deliver.

Probable (next quarter)

What: The 3-5 things we'll probably ship if everything goes well Confidence: 60-70% Detail: High-level scoped, some validation

This is your best guess. Share it, but emphasize: "This depends on how Q1 goes."

Possible (3-6 months out)

What: The themes and ideas we're exploring Confidence: 30-40% Detail: Directional only

This is strategic vision, not commitments. It shows where you're headed, not exactly what you'll build.

How to Handle Stakeholder Pressure

Stakeholders hate uncertainty. They want dates. They want commitments.

But giving false certainty is worse than admitting you don't know.

When they push for firm dates on the "Possible" tier:

"I can give you a date right now, but it'll be wrong. Or I can give you a more realistic estimate once we've validated the scope and dependencies. Which would you prefer?"

When they ask why the roadmap is so short:

"We're committing to what we can actually deliver, not what sounds impressive. Would you rather we promise 10 things and deliver 3, or promise 3 and deliver all 3?"

When they say "just work harder":

"We're already at capacity. To add something, we need to cut something else. What should we defer?"

Make the tradeoffs visible. Force the hard conversations.

The Validation Checkpoint

Here's the secret to roadmaps that work: validation before commitment.

Before you put something on the "Committed" tier:

• Prototype it to validate feasibility
• Test it with users to validate it solves the problem
• Scope it technically to validate complexity
• Identify dependencies to validate timeline
• Reserve resources to validate capacity

Only after validation do you commit. Otherwise, you're just guessing.

What Success Looks Like

A good roadmap:

• Ships what it promises (not necessarily on the exact date, but within the ballpark)
• Gets updated regularly as reality changes
• Shows tradeoffs explicitly so stakeholders understand choices
• Focuses on outcomes that move the business forward
• Accounts for uncertainty and leaves room for the unexpected

It's not about perfection. It's about transparency and realism.

The Roadmap Test

Want to know if your roadmap is realistic? Ask:

1. "If we shipped nothing else, would these 3 things move the needle?" If no, you're too scattered.
2. "Have we validated these are the right things to build?" If no, you're guessing.
3. "Do we have buffer for things going wrong?" If no, you're overpromising.
4. "Could we explain why we chose these over everything else?" If no, your prioritization is weak.
5. "Would we be okay showing this to the CEO in 3 months?" If no, adjust expectations now.

---

The bottom line: Most roadmaps are optimistic fiction that makes everyone feel productive until they fall apart. A real roadmap is honest about uncertainty, prioritizes ruthlessly, and ships what it promises.

The goal isn't to predict the future perfectly. It's to make better bets, ship consistently, and build trust by delivering what you say you will.
