The Product Requirements Document (PRD) is a crucial aspect of a product manager's responsibilities, as it outlines all features, functions, and requirements of the product, and serves as a guide for the entire development cycle.

The use of a PRD can help improve team communication and productivity during product development, but the process can be tedious. This article offers guidance on how to write a PRD efficiently using ChatGPT.

Part 1. What is a PRD and Why is it Important to Product Managers?

A Product Requirements Doc (PRD) is a document that outlines the features, design, testing, and success assessment of a product. It serves as a reference for the team and the final source of truth for the project.

Dismissing PRD writing as bureaucratic is a mistake as a well-written PRD is crucial for successful value delivery and offers many advantages in product management.

  • Improved Clarity: A PRD helps clarify the vision and scope of a product, ensuring everyone on the team understands the goals and criteria to avoid ambiguity and confusion.
  • Better Communication: A PRD is a communication tool used by several teams inside a firm, including product management, design, development, and quality assurance.
  • Risk Reduction: A PRD aids in the identification of potential risks or concerns that may arise during the product development process. It is very beneficial for grooming products or sprints.
  • Accountability: A PRD establishes clear expectations for the product development team, holding them accountable for delivering a product that matches the specifications.

Part 2. How To Use ChatGPT in Writing a PRD: 5 Examples

ChatGPT allows users to ask broad queries about any subject and receive tailored answers. How product managers can best take advantage of this AI is discussed below:

1. Writing Product Briefs

How well ChatGPT handles this task: ★★★★

A product brief summarizes critical product information that a product team will use to create a new product/feature. A decent product brief will assist in developing a robust product website.

ChatGPT can generate good briefs, but compared to actual briefs used in product design, it falls short of providing the necessary details required by product designers. For example, when relatively little information is available on the target audience.

2.Writing Copy for a Product Page

How well ChatGPT handles this task: ★★★★

Product designers are notorious for employing dummy texts in place of real texts. ChatGPT helps in creating a realistic copy much easier. Simply compose a question that describes your product type and let ChatGPT do the rest. For example, observe how the tool can handle writing copy for a landing page below.

3. Writing Success or Error Messages

How well ChatGPT handles this task: ★★★★

For example, messages of success and failure can significantly affect your users' satisfaction. ChatGPT can be used for both macrocopy (large text blocks like product descriptions) and microcopy (small text blocks like success and error warnings).

4. Writing a Marketing Copy

How well ChatGPT handles this task: ★★★★

What if it's necessary to encourage potential buyers to give the product a shot? Professional copywriters can encourage readers to try a product through persuasive writing. However, does ChatGPT work similarly? Yes, it can, but there might be some issues.

For example, the ChatGPT-generated marketing copy below is quite lengthy - 7 points, each of which is two words long. It’s not fascinating either - it doesn't have any unique benefits over competing products. And lastly, it just restates the information presented elsewhere in the product description.

5. Writing Codes for Product Pages

How well ChatGPT handles this task: ★★★★★

What if you wish to construct a programmed web page prototype? Most of the time, you use ready-to-use templates or design something from scratch utilizing a popular web framework. Then, can ChatGPT help with this? Take a look at the example given below. When ChatGPT was asked to develop a code for a responsive landing page, it produced a very simple responsive web, including HTML and CSS source code.

Unfortunately, this code only produces a simple page, making it unusable in any actual project.

Part 3. How To Write a PRD Using ChatGPT Step By Step

ChatGPT may be used in virtually every stage of a product workflow. Here are some examples of how to use ChatGPT for a product workflow using the correct prompts. These ideas may serve as a springboard for further exploration into the potential of large language model AIs like ChatGPT to streamline the product management process.

Step 1. Generating Ideas and Concepts

ChatGPT can be a collaborative space for developing new project ideas and concepts. It can function as a springboard for creative thinking.

Sample Prompt: Come up with three ways that an AI could improve a pedometer app.

Step 2. Exploring the Market and Investigating the Competition

ChatGPT is an excellent resource if you're curious about a market you're not familiar with.

Sample Prompt: Review the best five meditation apps and compare and contrast their features.

Note: The result might not be up-to-date since ChatGPT was trained on data from before 2021. However, it can provide a high-level overview of the industry and its players.

Step 3. Framing the Product

Generating user profiles and personas. Proto-personas and user profiles can be developed for your product with the help of ChatGPT. You can improve the effectiveness of your prompt by including information gleaned from genuine user research.

Sample Prompt: Develop a user persona for a middle-aged, working mother who values health and fitness but has no time to visit a gym.

Step 4. Writing a PRD

To save time writing, you can ask ChatGPT to construct a PRD to use as inspiration or tell it to expand based on your major bullet points.

Sample Prompt: Create a comprehensive product requirement document for the meditation app's social networking functionality. Users can form their groups and invite others to join them. The leaders of the groups can decide on the themes for group discussions. This document includes history, features, metrics, risks and mitigation, technological specifications, and primary user flows.
