Most organizations treat customer feedback like a transient email thread that vanishes the moment a project concludes. An evidence locker changes this by treating every interview, survey, and A/B test result as a durable asset. It is the difference between guessing what a user wants and having a searchable history of what they actually did.
When you build an evidence locker, you create a shared memory for the product team. It prevents the common cycle of re-learning the same lessons every quarter. By linking specific product decisions to the evidence that justified them, you provide the transparency needed to keep stakeholders aligned and delivery teams focused on outcomes.
Industry case01
The SaaS Knowledge Drain
Enterprise Software · CPO
A mid-sized SaaS firm realized they were conducting the same user interviews every six months because no one could find the notes from the previous year. They implemented an evidence locker to index all past research by user segment and feature area. Now, when a new feature is proposed, the team pulls up the relevant evidence from the locker before writing a single line of code.
Takeaway: Centralizing research prevents the expensive habit of repeating discovery work.
Executive perspective02
Evidence Over Ego
Fintech · CxO
I used to believe that my gut feeling on user needs was enough to guide the roadmap. I was wrong. After we built an evidence locker, I started asking my product leads to link every major roadmap item to a specific entry in the locker. It shifted our conversations from debating opinions to discussing the strength of our evidence.
Takeaway: Linking roadmap items to stored evidence forces a higher standard of strategic rigor.
Before and after03
From Silos to Shared Truth
E-commerce · PMO
Before the evidence locker, our design and engineering teams operated on different versions of reality. Design had the user feedback, but engineering only had the Jira tickets. After we integrated our feedback tools into a single evidence locker, the entire product trio could access the same raw data. We stopped arguing about what the user said and started building based on the same transcript.
Takeaway: A shared repository creates a single source of truth that aligns cross-functional teams.
Cautionary tale04
The Cost of Forgotten Lessons
Healthtech · CPO
A team spent three months building a patient portal feature that had actually been tested and discarded two years prior. Because the original research was buried in a personal folder of a departed employee, the team had no way to know the idea was already proven ineffective. They essentially paid for the same mistake twice.
Takeaway: Institutional memory is a competitive advantage that requires a formal home.
