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 |
