product, ux & customer framework
Measure experience via happiness, engagement, adoption, retention and task success.
quick answer
HEART Framework is a metrics matrix for UX metrics. It turns the decision into named fields, evidence, and a visible heart framework worksheet / visual.
The output should make the tradeoff visible enough for someone else to inspect, challenge, and act on.
Measure experience via happiness, engagement, adoption, retention and task success.
Use Goals-Signals-Metrics (GSM) when its output is closer to the conversation you need: Convert goals into observable signals and measurable metrics.
worked example
A filled example is easier to understand than a blank template. Use it to see the shape before applying the framework to your own case.
HEART ties experience goals to observable signals and metrics instead of measuring interface activity in isolation.

generate yours
Start Ask PL with the framework, required inputs, and your context. It will ask for missing details, render the metrics matrix, and explain what decision the output should change.
Apply HEART Framework to my situation. Context: [Decision, audience, options, evidence, and constraints.] Use the HEART Framework structure: - HEART categories: Happiness, Engagement, Adoption, Retention, Task Success: - GSM columns: Goals, Signals, Metrics: Ask only for missing inputs that would change the output. Then render the metrics matrix and name the decision it should change.
how to use it
Use the framework to change a decision, not to fill a worksheet. Start narrow, add evidence, then inspect what the heart framework worksheet / visual makes clearer.
Write the concrete ux metrics choice, tradeoff, or conversation the framework should change.
Fill the important slots: HEART categories: Happiness, Engagement, Adoption, Retention, Task Success, GSM columns: Goals, Signals, Metrics.
Mark what is measured, what comes from customers, and what is still judgment.
End with the next move, the riskiest assumption, or the evidence that would change the heart framework worksheet / visual.
quality check
Use this check after the artifact is filled. Blank fields are not failure; they are the next research question. Look for concrete evidence, missing constraints, and assumptions that would change the next move.
The framework needs a concrete decision. Broad intent turns it into a worksheet, not a decision aid.
Good framework output makes assumptions visible enough for someone else to challenge.
The diagram is useful only if it changes the next product conversation.
common mistakes
Do not use HEART Framework as a worksheet. Name the choice, conversation, or tradeoff the output should change.
Separate measured facts, customer evidence, and leadership judgment so weak assumptions stay visible.
If the diagram does not match the decision, switch frameworks instead of stretching the boxes.
The framework should clarify the next move. It should not replace strategy, sequencing, or judgment.
use something else when
Convert goals into observable signals and measurable metrics.
Connect mission, strategy, goals, roadmap and tasks.
Align vision, target group, needs, product, business goals and strategy.

Measure experience via happiness, engagement, adoption, retention and task success.
Business context; objectives; available evidence; stakeholder judgment
HEART Framework worksheet / visual
Use HEART Framework when the decision matches this job: Measure experience via happiness, engagement, adoption, retention and task success.
Avoid it when you need Goals-Signals-Metrics (GSM)'s output instead: Convert goals into observable signals and measurable metrics.
It is both: a structure for thinking and a visible metrics matrix that makes the decision easier to inspect.
A good input names the real decision, uses concrete evidence, and separates facts from assumptions.
Use the heart framework worksheet / visual to choose the next move, name the riskiest assumption, or decide what evidence would change the call.
Use Goals-Signals-Metrics (GSM) when the real output you need is closer to: Convert goals into observable signals and measurable metrics.
Yes. Describe your context and Ask PL can ask for missing inputs, render the metrics matrix, and explain what decision it should change.
