Section 1

Core Idea

Who, What, When, Where, Why, and How: six questions that force a complete brief. Applied to any initiative, product, or decision, they ensure you don't ship or commit without clarifying the actors, scope, timing, context, purpose, and method.

Section 2

How to See It

Product & Ops
You're seeing 5 W's and 1H when a spec or brief is structured explicitly around Who (users, stakeholders), What (scope), When (deadlines, phases), Where (channels, regions), Why (goals), and How (approach) before work starts.
Communication
You're seeing 5 W's and 1H when a pitch, memo, or update leads with the six answers so the audience gets the full picture in one pass instead of inferring missing pieces.
Section 3

How to Use It

Run the six questions at kickoff for any project, launch, or decision. Treat a missing answer as a risk: either fill it or document the assumption.
Decision filter
"Before we proceed: do we have a clear Who, What, When, Where, Why, and How? If one is fuzzy, we're not ready to execute — we're ready to resolve it."
As a founder
Use 5W1H for product briefs, go-to-market plans, and board updates. Require it for major bets so the team and investors see the same complete frame.
Section 5

Founders & Leaders

Jeff BezosFounder & CEO, Amazon, 1994–2021
Bezos insisted on clear, complete narratives in memos and PR/FAQs. The discipline — who is this for, what are we building, when and where does it ship, why does it matter, how will we do it — mirrors 5W1H. He used writing and structure to force clarity before commitment, reducing "we'll figure it out later" on the critical dimensions.
Section 7

Connected Models

Reinforces
5 Whys
5 Whys drills into cause; 5W1H lays out the full situation. Use 5W1H to define the problem or initiative, then 5 Whys to get to root cause when something goes wrong.
Tension
Start With Why
Start With Why prioritises purpose. 5W1H treats Why as one of six; sometimes Who or When dominates. The tension is productive: don't let Why override a missing Who or How, and don't let a full 5W1H bury a weak Why.
Leads-to
Jobs to Be Done
Jobs to Be Done answers "what job does this do for whom?" 5W1H sets the frame (Who, What, Why…); JTBD deepens the customer and outcome so you design for the job, not just the feature.
Section 8

One Key Quote

"I keep six honest serving-men (They taught me all I knew); Their names are What and Why and When and How and Where and Who."
— Rudyard Kipling, Just So Stories (1902)
Section 11

Summary & Further Reading

5 W's and 1H (Who, What, When, Where, Why, How) is a reference checklist for a complete brief. Use it at kickoff and in communication so nothing critical is assumed or omitted.
01
The Pyramid Principle — Barbara Minto (1987)
Book
Structured communication and clear situation definition; aligns with using 5W1H to shape memos and recommendations.
02
Start With Why — Simon Sinek (2009)
Book
Emphasis on purpose (Why) as the anchor; pairs with 5W1H by making Why explicit among the six.
03
Writing to Learn — William Zinsser (1988)
Book
How writing and structure force clarity; supports using 5W1H in docs and specs to think before acting.
