What if the proudest feature you shipped last month doesn’t make it to next year? Not because users didn’t want it, but because it was built to ship fast, not to last?
It is quite common in product development to focus on reducing time to market. Building fast. Shipping fast. Learning from the market and iterating continuously. Over time, speed starts to feel like the responsible choice. It looks like progress. It looks like learning.
At some point, speed becomes the default answer to almost every product question. But when we start talking about permanence of a product, a feature or a system, the picture changes.
The Illusion of Velocity
Speed changes what we pay attention to. Across many product teams, speed has gradually become a proxy for progress. Shipping faster signals responsiveness and alignment with the market. But it often favors visible output over lasting outcomes.
Permanence operates on a different timescale. It becomes visible only after multiple iterations, in what remains stable without constant explanation and in decisions that continue to make sense as context shifts. Permanence reveals whether what was built can endure beyond its own momentum. What ships fast is not always what stays meaningful.
Speed optimizes for the “now.” That’s why fast-moving products often feel like a collection of temporary patches. Permanence asks whether a decision will hold not just this quarter, but through the next pivot, the next market shift, the next team reorganization.
If we want to build things that last, we must distinguish between two types of decisions:
Reversible decisions: Speed is a virtue here because the cost of being wrong is low. You can undo them. You can change course.
Permanent decisions: These are structural choices. Architectural patterns. Data models. Core workflows. Speed becomes a vice here because the cost of getting it wrong compounds over time. Technical debt accumulates. Dependencies multiply.
The problem is that in the rush to ship, these two types of decisions start to look the same. But some decisions quietly lock in assumptions that will shape the product for years.
New Signals for Endurance
If permanence matters, we must rethink what we optimize for. Instead of asking how quickly something can be shipped, a more enduring question emerges: How long is this decision expected to hold?
Some signals of permanence are easy to overlook but reveal themselves over time.
Clarity Over Frequency
It’s not how often a feature is used, but how often it needs to be explained. A permanent feature eventually becomes “invisible” because it aligns so well with the user’s mental model that it stops requiring explanation.
Think about the features you use daily without thinking about them. Navigation patterns that feel natural. Workflows that match your expectations. The clearest features are often the quietest ones. They don’t generate feedback because they don’t create confusion.
Coherence Over Agility
It’s not how fast a roadmap changes, but whether its core direction remains coherent as the market shifts. A coherent roadmap can accommodate new information without abandoning its underlying logic. An incoherent roadmap changes direction with each new input, leaving behind a trail of half-finished initiatives.
This coherence isn’t about rigidity. It’s about having conviction in the decisions that matter while remaining flexible about the ones that don’t.
Dependency Awareness
How many other things would break if this changed? Features with few dependencies are easier to modify or remove. Features that have become structural have crossed into permanence whether you intended it or not.
Teams building for permanence pay attention to dependency formation. They design with modification in mind. They create boundaries that allow parts of the system to evolve independently.
The Two Modes of Product Thought
| Dimension | Speed | Permanence |
| Primary Goal | Validation | Coherence |
| Time Horizon | Next Sprint | Next Decade |
| Success Metric | Time to Market | Time to Obsolescence |
| Nature of Choice | Reversible | Structural |
The Survival of the Quietest
Over time, products reveal what they were truly optimized for. Speed shows itself early in the form of high-frequency updates and visible momentum. Endurance takes longer to surface.
You find it in the quiet parts of a system that haven’t changed in years—not because they were forgotten but because they were right the first time. A data model that still makes sense. A workflow that new features naturally integrate with.
If we optimize only for speed, we risk running very fast toward a product that won’t exist in three years.
To build for permanence is to accept a different kind of measurement: the measurement of what stays.
The features that last aren’t always the ones we celebrated shipping. They’re the ones we stopped talking about—because they simply work.
