Tiered Pricing: One Product, Many Prices
Tiered pricing sells one product at multiple prices by packaging features for different customer needs. It's common in SaaS (Basic, Pro, Enterprise plans) and telecoms.

Negative Churn: When Losing Customers Still Means Growth
Negative churn means existing customers upgrade faster than others leave, growing your revenue even if you lose logos. It's a key SaaS metric for variable pricing models. The footgun: you can have negative revenue churn while still losing many customers.

Streaks: Engineering Identity Through Loss Aversion
Streaks convert effort into identity, making users fear losing progress more than they enjoy extending it. Apps like Duolingo use this for daily engagement, but the footgun is when the streak itself becomes the goal, trapping users in a loop of loss aversion.

Personalized Onboarding: One Size Fits None
Personalized onboarding guides users based on their role or goal, not a generic script. It's key for apps with diverse user types, showing marketers and engineers different paths to value. The footgun is a one-size-fits-all tour that buries their "aha!"

Interactive Walkthroughs: Learn by Doing, Not Just Seeing
An interactive walkthrough teaches by doing. Instead of clicking 'Next,' users must perform the actual task to advance. It's best for critical onboarding flows where learning a workflow is key to activation.

Progressive Disclosure: Show Less, Reveal More
Progressive disclosure manages complexity by showing only essential features upfront, like a "Read More" button for your UI. It's used in print dialogs and e-commerce specs to avoid overwhelming users.

Setup Wizard: Guiding Users Through Complexity
A setup wizard turns a complex form into a simple, step-by-step conversation. It's ideal for infrequent but critical tasks like software installation, where the system determines the next best step. The footgun: A true wizard alters the user's *path*.

Content Marketing: Earn Trust, Not Just Clicks
Content marketing earns trust by giving away valuable information for free. It's used in company blogs or whitepapers to attract an audience by solving their problems, not just pushing a product.

Regression to the Mean: Why Outliers Settle Down
Extreme results are part skill, part luck. Regression to the mean is the principle that luck evens out, so a follow-up measurement will be closer to the average. This impacts A/B tests and performance analysis.

The RICE Scoring Model: Prioritize with Data, Not Feelings
RICE is a formula—(Reach × Impact × Confidence) / Effort—for scoring competing features. It replaces gut feelings with a data-driven framework for prioritizing product roadmaps. The biggest footgun is treating the score as gospel, not a conversation starter.

Hypothesis-Driven Development: Test Your Ideas Before You Build
Hypothesis-Driven Development treats product work as a series of experiments, not a to-do list. You state a testable belief ("If we build X, users will do Y") before writing code. This de-risks new features by validating ideas early.

Fogg Behavior Model: Why Users Act (or Don't)
The Fogg Behavior Model states a behavior only happens when Motivation, Ability, and a Prompt converge (B=MAP). Use it to diagnose why a feature fails or to design new ones. The footgun is blaming low motivation when the real issue is low ability.

Schema-on-Read vs. Write: Pay for Structure Now or Later?
Schema-on-Write pays to structure data upfront for fast, consistent reads. Schema-on-Read defers this cost to query time for flexible ingestion. This choice underpins relational databases (write) vs. data lakes (read). The footgun is creating a data swamp.

The Data Layer: A Central Hub for Website Events
A data layer is a central JavaScript object acting as a message bus between your site and analytics tags. It passes event data, like button clicks or purchase values, in a structured way. The key footgun: never overwrite it; always use `dataLayer.push()`.

User Activation: Engineering the 'Aha' Moment
User activation engineers the 'aha' moment when a new user first experiences your product's value. It's measured by a key action, like sending a message in Slack, that predicts retention.

User Journey Mapping: Seeing Your Product Through a User's Eyes
A user journey map tells the story of a user achieving a goal, visualizing their actions, thoughts, and feelings from start to finish. It's essential for understanding complex, multi-channel processes.

The Pivot: A Structured Change in Strategy, Not Vision
A pivot is a structured course correction, not a restart. You change strategy based on validated learning from your MVP when data shows your initial hypothesis was wrong. The footgun is pivoting on a whim instead of data, or failing to pivot despite it.

ICE Score: A Quick Framework for Prioritizing Ideas
The ICE score is a quick framework for ranking ideas by asking: what's the potential Impact, our Confidence in the outcome, and the Ease of implementation? Growth teams use it to prioritize experiments, balancing big bets with quick wins.

High-Tempo Testing: Move Faster Than Your Channels Decay
High-tempo testing treats growth as a continuous experiment, not a one-time campaign. Since marketing channels decay quickly, this lets you find new wins across the entire user journey.
