What types of requirements are often hidden?

Good day @simon_tomes ,

Hidden requirements often arise from assumptions, overlooked details, or implicit expectations. These can include usability considerations, edge cases, scalability needs, compliance standards, or even the unspoken priorities of stakeholders.

For example, during a project where I tested a new user interface, I realized the requirements didn’t specify accessibility standards. This gap became apparent during exploratory testing, where I identified usability challenges for screen reader users. To address this, I facilitated discussions with the product owner and design team, highlighting the risks of excluding accessibility as a requirement.

To turn this into an official requirement, I documented the findings, aligned them with accessibility guidelines (e.g., WCAG), and presented a proposal to incorporate these standards into the project. Once the team agreed, we added it to the product backlog and tested against the updated requirements. This process not only improved the product but also fostered a culture of inclusivity in future projects.

Discovering hidden requirements often involves a mix of asking probing questions, reviewing real-world use cases, and conducting exploratory testing. Have you encountered situations where a hidden requirement significantly impacted your project outcomes? How did you handle it?
