Today, company spending is under intense scrutiny. Budget reviews are stricter, investment in new work is slowing, and every team is being asked to do more with less. In this environment, product leaders must do more than build well, they must make better cases for why their work is worth funding at all.
Product discovery often gets sidelined in investment conversations. It can appear abstract, slow, or hard to quantify. But in reality, it’s one of the highest-ROI activities a product team can invest in. The key is knowing how to explain that—clearly, credibly, and in business terms.
At its core, product discovery is a business safeguard. It’s how teams ensure they don’t waste time, money, and goodwill building something no one wants.
Every product idea begins with assumptions. Discovery is the disciplined process of testing those assumptions before further investing in product development. It’s the product equivalent of due diligence—just as no executive would acquire a company without a financial audit, no product team should invest in a new feature without verifying its potential.
Discovery doesn’t just prevent mistakes; it enables smarter bets. It ensures your team invests in solving real problems, not imagined ones.
It’s tempting to reduce discovery to a gatekeeping function—something that helps you kill bad ideas before they reach delivery. But that undersells its value.
Discovery also helps teams shape and mature promising ideas. It turns rough hypotheses into refined opportunities. Done well, it improves the hit rate of your product bets, not just by subtracting risk, but by increasing the chances that what you build will actually work.
This nuance is essential when speaking to stakeholders. Discovery isn’t just a filter—it’s a multiplier for product success.
Consider a simple example: a team wants to build a feature that lets customers reorder past grocery purchases with a single click. The assumption? That customers buy the same items regularly and want a faster way to repeat orders.
If the team skips discovery and goes straight to build, they might burn weeks of design, development, QA, documentation, marketing, and sales effort—only to find that the feature is irrelevant. No one uses it. No new revenue is generated. Given the significant run cost of most teams, this leads to significant waste.
A few hours of discovery—a quick user survey or review of in-branch activity—could have invalidated the idea before a single line of code was written.
Multiply that scenario across all product bets, and the stakes become clear.
Product discovery is not only about cost avoidance. It directly supports both product stability and business growth.
When you consistently ship features that solve real problems, customers stay. Retention improves. Product quality compounds.
When you validate new opportunities before building, you increase the likelihood that new features drive revenue—whether through acquisition, upsell, or expansion.
Skipping discovery breaks this cycle. Teams ship features that miss. Confidence drops. Velocity slows. Churn creeps in. Growth stalls. You end up running fast in the wrong direction.
Discovery is a cross-functional activity—but it must be led by Product Managers.
PMs sit at the intersection of commercial strategy, user understanding, and delivery planning. They’re best positioned to shape hypotheses, weigh trade-offs, and ensure findings translate into product direction.
When discovery ownership shifts to designers or developers, delivery slows. Dual-track agile collapses. The same people trying to ship are now also trying to validate. Momentum suffers.
PM-led discovery ensures discovery and delivery run in parallel—one track researching what to build next, the other executing on what’s already been validated. That’s how you maintain strategic clarity without losing speed.
You don’t need perfect data to prove ROI. You need a credible, directional argument grounded in the business’s own numbers.
Here’s a simple formula:
ROI = (Benefit – Cost) / Cost × 100
In discovery, the benefit is often the cost avoided by not building the wrong thing. The cost is the time a PM spends validating the idea.
In one real-world example, a Product Manager spent a week doing discovery on a proposed feature. Total cost: ~£2,600.
That work prevented the team from building a feature that, if fully developed and launched, would have cost ~£46,000.
ROI = (£46,000 – £2,600) / £2,600 × 100 = 1,574%
It’s a compelling number—and far from an outlier. Industry benchmarks suggest UX research alone yields a 10x return in development savings and up to 100x in post-launch costs.
You don’t need to wait for the perfect case study to start making your case. Look back over your backlog. Identify ideas you invalidated during discovery. Estimate what they would have cost if they’d gone ahead.
You’re not aiming for forensic accounting—just a reasoned estimate that puts a stake in the ground.
Use that to build a short internal deck or talking points for leadership. Show not just what didn’t happen, but what was avoided—and how much it saved.
Over time, keep a log of these decisions. Pattern recognition will do the rest.
In a world where product teams are under pressure to prove their worth, product discovery is one of the clearest lines you can draw between your role and measurable business value.
It’s not an abstract process. It’s due diligence. It’s financial responsibility. It’s the discipline that ensures your product strategy is grounded in truth, not guesswork. Product discovery is the difference between building fast—and building smart.
