The 20-Page Spec Nobody Read
We used to write comprehensive specs.
20+ pages. User stories. Acceptance criteria. Wireframes. Flows.
Developers would skim them. Miss details. Build wrong things.
The spec became documentation for a product nobody built.
The One-Page Spec
One page. Maximum.
Section 1: The Problem (3 sentences)
- Who has this problem?
- What is the problem?
- Why does it matter?
Section 2: The Solution (1 sentence)
How does this product solve it?
Section 3: The User Flow (Visual)
Not paragraphs. A diagram.
Signup -> Do X -> Get Y.
Section 4: Success Metrics (3 bullets)
- How will we know this works?
- What numbers matter?
- What are the targets?
Section 5: What's NOT In Scope (List)
Explicitly state what's excluded.
Why This Works
1. Writers think clearly
Forcing clarity into one page exposes fuzzy thinking.
If you can't explain it simply, you don't understand it.
2. Readers actually read it
Nobody reads 20 pages.
Everybody reads one page.
3. Details emerge in conversation
Instead of documenting edge cases, discuss them.
Get on a call. Walk through the flow. Questions get answered immediately.
4. Flexibility preserved
A 20-page spec feels like a contract.
A one-page spec invites collaboration.

The Real Answer
The spec isn't documentation. It's communication.
One page forces clarity. Forces discussion. Forces prioritization.
That's the goal: shared understanding.
Not comprehensive documentation.
Stop writing specs. Start writing clarity.
