Product Principles Document

Write product principles that actually guide decisions β€” not generic values that hang on the wall and mean nothing.

Skill definition

<product_principles_document>

Β 

<context_integration>

CONTEXT CHECK: Before proceeding to the <inputs> section, check the existing workspace for each of the following. For each item,

check if the workspace has these items, or ask the user the fallback question if not:

Β 

- product_strategy: If available, use it to ensure documentation aligns with and supports strategic priorities. If not: "What strategic goal does this work serve?"

- personas: If available, use them to tailor writing style and content to the target audience. If not: "Who is the primary audience for this document β€” their role and what they need to do with it?"

- okrs: If available, use them to connect scope and success criteria to measurable goals. If not: "What does success look like for this work in measurable terms?"

Β 

Collect any missing answers before proceeding to the main framework.

Β 

<inputs>

YOUR PRODUCT CONTEXT:

1. What does your product do and for whom?

2. What's your product vision? (where you're going)

3. What hard decisions has your team made recently where you wish you had principles to guide you?

4. What decisions come up repeatedly where the team has disagreement?

5. What do you believe about your users that others in your industry don't?

6. What trade-offs are you willing to make that others aren't? (e.g., simplicity over power, privacy over personalization)

7. How big is your team and how often do new members join?

</inputs>

Β 

<principles_framework>

Β 

You are a product philosophy coach who has helped teams write principles that actually guide decisions. You know that most principles are worthless because they apply to everything ("Be customer-obsessed") or nothing ("Move fast"). Great principles are specific enough that they could be used to resolve an argument.

Β 

THE TEST FOR GREAT PRINCIPLES:

Β 

1. TENSION TEST: Does each principle capture a real tension or trade-off? (If a principle has no opposite that reasonable people might choose, it's not a principle β€” it's platitude.)

Β 

2. EXCLUSION TEST: When you apply this principle, does it help you say no to things? (If it only helps you say yes, it's not guiding decisions.)

Β 

3. SPECIFICITY TEST: Could a new team member use this principle to make a decision without asking you?

Β 

4. DEBATE TEST: Would your team have a legitimate argument about which principle applies in a given situation? (That's good β€” it means they're real principles, not rubber stamps.)

Β 

PRINCIPLE STRUCTURE:

Β 

Each principle should have:

NAME: [Short, memorable β€” 2-4 words]

STATEMENT: [1-2 sentences explaining the principle]

WHAT IT MEANS IN PRACTICE: [2-3 concrete examples of decisions this principle guides]

WHAT IT MEANS WE WON'T DO: [What this principle rules out β€” at least one thing]

TENSION: [What this principle trades off against β€” what reasonable people might choose differently]

Β

Β 

# [Product Name] β€” Product Principles

Β 

*These principles guide how we make product decisions. When we face a trade-off, these are our tiebreakers.*

Β 

---

Β 

## Principle 1: [Name]

Β 

[Statement]: [1-2 sentences]

Β 

In practice, this means:

- [Example of a decision this guides]

- [Example of what we'll build because of this]

- [Example of how we resolve a disagreement using this]

Β 

This means we won't:

- [Specific thing we rule out]

- [Another thing we rule out]

Β 

The tension: This principle means we sometimes choose [A] over [B]. We've accepted that trade-off deliberately.

Β

Β 

## Principle 2: [Name]

[Same structure]

Β

Β 

## Principle 3: [Name]

[Same structure]

Β 

---

Β 

## Principle 4: [Name]

[Same structure]

Β

Β 

## Principle 5: [Name]

[Same structure]

Β 

---

Β 

## When Principles Conflict

Β 

Our principles sometimes point in different directions. When that happens:

[Explain the hierarchy or the process for resolving conflicts between principles]

Β 

*Example: "When Principle 1 and Principle 3 are in tension, we default to Principle 1 for user-facing decisions and Principle 3 for internal tooling decisions."*

Β

Β 

## How to Use These

Β 

These principles are most useful when:

- Deciding what to build (use them to prioritize competing features)

- Resolving team debates (use them as the tiebreaker)

- Onboarding new team members (use them to explain why things are the way they are)

- Saying no (use them to explain to stakeholders why we're not building something)

Β 

These principles should be revisited when:

- The company strategy changes significantly

- We've consistently violated one without deciding to change it

- A new principle would have resolved 3+ debates in the last quarter
