working-backwards

name	working-backwards
description	Use when asked to "working backwards", "PR/FAQ", "Amazon PR/FAQ", "write a press release", "define a new product", or "write a customer-focused PRD". Helps define products by starting with the customer problem and desired outcome before building. The Working Backwards process (developed at Amazon) forces clarity on customer value before committing engineering resources.

Working Backwards

What It Is

Working Backwards is Amazon's product development methodology. The core insight: start with the customer problem and work backward to the solution, not the other way around.

Most teams work forward: "We have this technology/capability/idea — what can we build with it?" Working Backwards inverts this: "What problem does the customer have? What would the ideal solution look like? Now, how do we build it?"

The mechanism: Write an internal press release and FAQ before building anything. If you can't write a compelling press release, you don't have a compelling product.

As Jeff Bezos put it: "We took it as an article of faith — if we served customers well, if we prioritized customers and delivered for them, things like sales, revenue, and free cash flow would follow."

When to Use It

Use Working Backwards when you need to:

• Define a new product or major feature before committing resources
• Evaluate competing product ideas and choose which to build
• Align stakeholders on what you're building and why
• Force clarity on vague product concepts
• Prevent building solutions in search of problems
• Create a shared vision that engineering, design, and leadership can rally around
• Decide whether an idea is worth pursuing at all

When Not to Use It

• The work is incremental optimization (A/B tests, bug fixes)
• You're executing on an already-defined product
• The scope is too small to warrant the overhead
• You're just exploring technical feasibility (do that first, then write the PR/FAQ)

Patterns

Detailed examples showing how to apply Working Backwards correctly. Each pattern shows a common mistake and the correct approach.

Critical (get these wrong and you've wasted your time)

Pattern	What It Teaches
solution-first-thinking	Don't start with the solution and retrofit a problem
missing-problem-paragraph	If you skip the problem, there probably isn't one
vague-customer-definition	"Everyone" is not a customer — be specific
writing-pr-after-building	The PR comes first, not as documentation after
internal-jargon-in-pr	Press releases are for customers, not engineers

High Impact

Pattern	What It Teaches
faq-avoids-hard-questions	The FAQ must address what makes you uncomfortable
hyperbole-instead-of-specifics	No marketing fluff — use data and concrete claims
customer-quote-sounds-fake	Customer quotes reveal whether you understand the job
too-many-features	One press release, one compelling benefit
no-measurable-outcome	Define what success looks like with numbers
combining-ideas	One PR/FAQ per idea — don't bundle concepts

Medium Impact

Pattern	What It Teaches
skipping-the-iteration	PR/FAQs improve through concentric circle review
missing-the-date	The hypothetical launch date signals ambition and scope
faq-too-short	External and internal FAQs serve different purposes
