The document explains how a strong product requirements document (PRD) enables a company to build, test, and align a product with clear purpose, features, functionality, and behavior. It emphasizes that a well-crafted PRD increases the likelihood of success, while a poorly defined PRD makes a good product nearly impossible. It also contrasts PRDs with market requirements, product strategy, and roadmaps. A repeatable ten-step process guides authors through preparation, value proposition definition, and user goals, helping teams make better trade-offs during development.

How To Write a Good PRD Martin Cagan Silicon Valley Product Group HOW TO WRITE A GOOD PRD Martin Cagan, Silicon Valley Product Group OVERVIEW The PRD describes the product your company will build. It drives the efforts of the entire product team and the company’s sales, marketing and customer support efforts. It’s hard to come up with a more important, higher leverage piece of work for a company. The purpose of the product requirements document (PRD)1 or product spec is to clearly and unambiguously articulate the product’s purpose, features, functionality, and behavior. The product team will use this specification to actually build and test the product, so it needs to be complete enough to provide them the information they need to do their jobs. If the PRD is done well, it still might not be a successful product, but it is certain that if the PRD is not done well, it is nearly impossible for a good product to result. 2 The PRD versus the MRD We draw a distinction here between the product requirements and the market requirements (often referred to as the GMRDI) . Put very simply, the market requirements describe the opportunity or the market need, and the product requirements describe a product that addresses that opportunity or need. The PRD versus the Product Strategy and Roadmap The product strategy describes a vision, typically between two and five years out, of where you want the product to go, and the product roadmap describes the various steps to get there. The PRD describes a particular product release along that path. 1 Note: Different companies and industries use different terms or acronyms to refer to the product requirements. Similarly, some use a single document to capture market, product and interface requirements, and others use a series of documents. For our purposes, we simply refer to the Gproduct requirementsI and use the acronym PRD. We intentionally do not refer to MRD which we consider distinct. 2 This paper is based in part on the notes and insights of Ben Horowitz, President and CEO of Opsware. © 2005 Silicon Valley Product Group Page 1 [www.svproduct.com](www.svproduct.com) TEN STEPS TO A GOOD PRD The purpose of this paper is to describe a proven, repeatable process to create a good PRD. The ten steps described here are not easy, but they can help you produce a strong PRD. The amount of time this process takes depends greatly on the size and complexity of your product, and how prepared you are in terms of the knowledge and skills required. Step 1: Do Your Homework Your goal with the PRD is to come up with a compelling product. In order to do this, you must do your homework. This means studying your customers, your competitors, and your team’s capabilities, including available technologies. This begins with customers, users, competitors, industry analysts, your product team, your sales force, marketing, company executives, other employees – anyone that has insight into the problem and possible solutions. There is much more to the process of preparing, and this is discussed in detail in the paper GBehind Every Great ProductI also available from the Silicon Valley Product Group. Realize also that a significant factor in your ability to convince the team of the eventual success of the product is the degree of confidence you project, and you will be more confident and more convincing if you’ve done your homework well. Step 2: Define the Product’s Purpose Every good product starts with a need that it is trying to fill. You must have a clear understanding of that need, and how your product addresses that need. It is essential that the product manager establish a very clear, concise value proposition that lets her easily communicate to everyone – the product team members, company executives, customers, the sales force – what the point of this product really is. While this sounds obvious, few products have such a clear value proposition. Consider the Gelevator

FAQs

What is the purpose of a PRD in product development?

A PRD clearly and unambiguously articulates the product’s purpose, features, functionality, and behavior so the product team can build and test it. It also aligns sales, marketing, and customer support around a shared understanding.

How does a PRD differ from an MRD and from product strategy or a roadmap?

Market requirements (MRD/GMRD) describe the market need or opportunity, while product requirements describe the product that addresses it. The product strategy provides a long-term vision and the roadmap outlines steps, while the PRD specifies a particular release along that path.

What are the key starting steps for creating a good PRD?

The process begins with homework: studying customers, competitors, and team capabilities. Next, define the product’s purpose and value proposition, including measurable objectives prioritized for the specific release.
