The PRD is the heart of your product and serves as a living document for any designer, developer, or stakeholder to understand the status and purpose of the product.
I found this in the UXpin book. As illustrated above, failure to document requirements can lead to wildly different assumptions. Because there’s been debate around the danger of excessive design thinking as well as its vital role in product leadership, the PRD helps balance the design team’s focus on usability and aesthetics against engineering’s functional concerns. Getting signoff from all teams on the PRD helps you avoid disaster. For a detailed PRD, you can reference this expansive Product Requirements Document Template.
Or let us know about your product and may be we can work together.
