5 docs PMs spend too much time writing (and how to replace them)

PMs don’t become PMs because they love writing documents. But somehow, writing takes up half the job. Between outlining PRDs, cobbling together launch briefs, and manually chasing updates for release notes, documentation starts to feel like the real product.

‍

The worst part is most of it gets ignored, duplicated, or buried. Docs quickly go stale, threads get long, people ask for the same info again and again. And you’re stuck rewriting the same thing in five different formats, in five different places.

‍

The problem isn’t the writing itself. It’s the disconnected tools, fragmented formats, and outdated habits that turn documentation into a black hole. Let’s look at five common time-sinks PMs get pulled into — and how you can reclaim that time with smarter, system-connected approaches.

1. The “what are we even building?” overview

It always starts with a noble goal: rally the team around a feature’s purpose. But the reality is a long doc, trying to articulate the “why,” that ends up vague or unread. You explain the user problem, the business case, the opportunity… but people still ask, “Wait, what exactly are we building?”

‍

The truth is, abstract vision doesn’t land without something tangible. Instead of writing a wall of text, create something that shows what’s coming. A short prototype walkthrough, a snapshot of how it fits into the product system, or even a narrated Loom video. When people can see the idea, they get it faster. And when the story connects to real user pain and business value, it actually sticks.

2. The never-finished PRD

The PRD starts as a helpful outline. Then comes the pressure to account for every possible case. You add sections, rewrite assumptions, chase feedback, add more detail, and before long, you’ve got a 15-page doc no one finishes reading.

‍

It doesn’t have to be this way. Instead of trying to write the doc, focus on creating modular, structured inputs. A clearly defined goal. A scoped list of impacted components. Known dependencies. Linked patterns and flows. Break big ideas into building blocks grounded in your actual product system. 

‍

That makes it easier for contributors to collaborate, and even easier for AI tools to help with the heavy lifting — whether that’s summarizing, translating into developer-ready outputs, or spotting edge cases.

3. The Slack-scrap launch brief

Launch planning often starts with chaos. One thread in Slack, a brainstorm doc in Notion, a draft in Google Docs. The team asks, “What’s actually going live next week?” and you find yourself backtracking through six tabs and your memory.

Without a single, visible plan, people operate on assumptions. Some teams over-prepare. Others get dormant and miss the launch entirely.

What works better is a centralized, dynamic launch brief that pulls in info directly from your roadmap and system components. You can tailor it for different audiences — product teams, marketing, support — so each group sees just what they need. And with a designated source of truth and shared comms channel, there’s less chasing and fewer surprises.

4. The painfully manual release notes

You know the drill. Dig through GitHub. Ask the designer what shipped. Check if that UI update made it in. Then try to write it all up in a way that’s accurate and understandable for end users. It’s tedious, error-prone, and never feels like a good use of your time.

But your tools already know what shipped. You just need to connect the dots. Pull structured data from your source of truth — whether that’s Supernova, GitHub, Figma, or your design system — and use AI to generate a first draft. Then do a quick PM pass to make it better. It’s faster, cleaner, and lets you spend time where it actually matters: framing the value for users.

5. The over-explained wireframe doc

Describing a product flow in words seems straightforward until it isn’t. You write out each step, try to capture intent, include logic, and maybe throw in a screenshot or two. But designers still miss key details, engineers make assumptions, and what gets built veers off course.

Text isn’t the problem. Ambiguity is. Instead of explaining flows in paragraphs, show them using prototypes built on real system components. Annotate where logic or edge cases apply. Link to reusable patterns to anchor expectations and that way, the team isn’t guessing.

‍

Less writing. More showing.

PMs aren’t hired to write docs. They’re hired to drive alignment and momentum. That’s why the goal isn’t more documentation. It’s better-connected documentation — faster to produce, easier to understand, and grounded in your system of record.

When your building blocks are structured, your outputs can be smarter. Your team stops rewriting. Your roadmap gets clearer. And you finally get to focus on what you were actually hired to do.
