How to Write Product Requirements

A good Product Requirements Document (PRD) defines the purpose and features of a product: the overall vision of your build, product goals and the features required to achieve each goal, details about how an end user will interact with your build and how it will appear to them. With today’s agile development, features are added to the backlog and prioritized. Don’t get specific in your PRD: for example, don’t specify any languages to be used. You’ll have engineers for that – let them decide. The Agile way – adaptability is vital and defining such things in a PRD sets them in stone.

Gathering Agile Requirements

Agile requirements rely on the product owner, designer and development team sharing a deep understanding of the customer. With everyone on the same page, implementation is left to the dev team, who is fully capable of handling it thanks to this shared understanding.

How long should your PRD be?

As a PRD gives you the big picture of what a product should or shouldn’t feature, you could have a one page PRD for a simple app, or a much more complex one for an accounting SaaS platform which requires complex algorithms, a backend, multiple use cases and wireframes.

Ensuring teams have a shared understanding prior to documentation

This shared understanding of the customer is vital for any agile PRD. To accomplish it:

  • Create a customer interview template and ensure that members of your design and dev teams are included when you conduct customer interviews. The benefits are obvious: nobody has to rely on the product owner’s notes, and all teams have a deeper understanding of the customer’s wants.
