Product Requirements: Understanding and Documenting What Your Users Need

Product requirements are the specific features, functions, and characteristics that a product must have in order to meet the needs of its target users. These requirements serve as a roadmap for product development and help ensure that the end product meets the expectations of the users it is designed for.

Why are product requirements important?

Product requirements are important for several reasons:

  • They help define the scope of the product and what it should achieve
  • They provide a clear understanding of the target user and their needs
  • They serve as a basis for design and development decisions
  • They help to manage expectations of stakeholders and ensure that everyone is working towards the same goal

What is usually included in product requirements?

Product requirements can vary depending on the product and the needs of the target user. However, there are some common elements that are usually included in product requirements:

  • Product goals: The goals of the product are the main reason it exists. They are the reason the product was created and the reason it will be used.
  • Target user: The target user is the person or group of people that the product is designed for. This information is important because it helps to define the product’s features and functions.
  • Product features: Product features are the specific characteristics of the product. They are the things that make the product unique and help it stand out from the competition.
  • Product functions: Product functions are the specific actions that the product can perform. They are the things that the product can do and the ways in which it can be used.
  • Product constraints: Product constraints are the limitations that the product must adhere to. These can include technical limitations, budgetary constraints, and legal requirements.

How to create product requirements

Creating product requirements is a crucial step in the product development process. To create effective product requirements, follow these steps:

  1. Define the target user: Start by understanding who the target user is and what their needs are. This information will inform the development of the product requirements.
  2. Conduct research: Gather information about the target user and the market they belong to. This can include market research, customer surveys, and competitor analysis.
  3. Create a requirements document: Using the information gathered in the previous steps, create a detailed requirements document that outlines the goals, features, and functions of the product.
  4. Validate the requirements: Once the requirements document has been created, validate it with stakeholders, including the target user, to ensure that it meets their needs and expectations.
  5. Revise and finalize: Based on feedback from stakeholders, revise and finalize the requirements document. This will serve as the foundation for the design and development of the product.

Using DiscoveryBuddy to create product requirements

DiscoveryBuddy makes it easy to create and manage product requirements. The app automates the process of gathering information about the target user and the market they belong to, and creates a draft requirements document for you. You can then edit and refine the document to ensure that it meets the specific needs of your target user.

You can see a demo of the product requirements generation process below. In this example, we've used data from a project to generate a persona, but you can also use DiscoveryBuddy to generate a requirements document.
