PRD (full)

A full PRD is justified for a complex, risky, or inter-team initiative where the loss of context is more expensive than the preparation of a document. Fill out sections as needed and explicitly note the unknown; the volume of the text does not compensate for the weak evidence of the problem or the absence of the owner of the solution.

What is PRD?

Brief definition

PRD is a structured document that explains what product should be made, why, for whom and what parameters it should have. It is read by developers, designers, testers, business and other teams.

Example of application

The team is launching a new onboarding process in mobile banking. Without PRD, different departments will see the task in their own way, with timelines and goals blurred. After agreeing on PRD, everyone agreed on one description and set of requirements: what the user sees, what happens on the server, how to count success, what restrictions on tech debt.

The basic structure of PRD

Universal form

1. Description of the task
2. Product Objectives (Product Objectives)
3. User Scenarios (User Stories/Flows)
4. Basic Requirements (Functional Requirements)
5. Limitations and non-included requirements (Out of scope)
6. Metrics of success (Success Metrics)
7. Technical and non-functional requirements
8. Validation and Acceptance Criteria
9. Taiming and risk

Example: short template

1. Problem: Long profile filling prevents users from getting started quickly.
2. The goal is to reduce the average filling time by 30%.
3. Scenarios: A new user registers and immediately ends the onboarding.
4. Requirements: form auto-filled, support for mobile, integration with backend.
5. Out of scope: profile redesign, multi-account.
6. Metrics: Time from registration to first action.
7. Technical: API v2 support, WCAG availability.
8. Criteria: The user completes the process in less than 2 minutes.
9. Risks: Integration with an outdated CRM

Comparison of short and full PRD

The full version adds detail: what to test, links to layouts, specific APIs, schedule and description of edge cases. The short form is suitable for improvements within a small team. Full is needed to launch large projects when several departments are involved.

Requirements that cannot be missed

Functional vs. non-functional requirements

Functional describes what the product does at the level of feature. Non-functional – how exactly it does it (speed, security, UX, device support).

Example

Requirement: The Save button should work on poor internet. This is non-functional: you need to describe the level of stability and, for example, the interface’s response to an error.

Limitations (Out of scope)

Without the Out of scope designation, developers often add extra tasks or suggest implicit extensions. Describe clearly what is not being done within this feature or release.

Common mistakes in PRD and how to avoid them

Nebula of wording

Phrases like improving efficiency or making it convenient don’t give developers or designers a clue what to achieve. Always write with testable criteria: what **means ** effectively, how **measure ** the result.

Absence of metrics

PRD without metrics turns into a postcard on feelings. Add object metrics: script execution rate, user percentage, errors, conversion, NPS – what can be measured after the release.

Forgotten communication

The uncoordinated PRD does not reduce risks, but increases them: designers work on one layout, testers on another, developers code from memory. Check that the document was agreed by key stakeholders.

Checklist for PRD control

Questions for self-testing

1. Is the purpose and reason of the task defined?
2. Are there consistent user scenarios?
3. Are the requirements clearly described at the level required for development and testing?
4. Are there any criteria for successful acceptance?
5. Are there any restrictions or areas not covered?
6. Are the success metrics clear and where to get the data to check?
7. Is PRD agreed between the teams: design, virgin, QA, business?

Example of the use of a checklist

Before launching the new analytics section of the b2b product, the team went through a seven-point list. It turned out that they did not define success metrics – in the end, they added tracking of the necessary user actions to validate the hypothesis of benefits.

FAQ: Frequently asked questions

What is the standard PRD format? There is no single standard, but the basic blocks coincide on most large projects: goals, requirements, scenarios, acceptance criteria, metrics, out of scope, risks.

What is the difference between PRD and BRD? The Business Requirements Document (BRD) captures the business’s mission and benefits, while the PRD details what needs to be built with a focus on the product and user.

Who writes PRD? Most often PM or PO, but check and finalize with the development team, design, QA and business stakeholders.

**Do I need to create a full PRD for every new feature? No, for quick fixes. For major changes, new modules or custom solutions, yes.

**What happens when the requirements change frequently? Make a PRD versioning and note what changes have occurred and when. This will help the team to keep the context in mind and update the document faster.

*PrD is always the text? No, you can use diagrams, prototypes, tables – the main thing is that the team was comfortable working with the requirements and there were no different interpretations.
