G.R.O.W.S. Framework

Gather Ideas:

• Brainstorm growth hypotheses

• Ease: Resources required (1-10)
• ICE Score: (Impact + Confidence + Ease) / 3

Outline Experiments:

• Define hypothesis
• Set success criteria
• Determine sample size
• Plan implementation
• Estimate timeline
• Assign ownership

Work (Execute):

• Build minimum viable test
• Launch experiment
• Monitor in real-time
• Collect data
• Document process

Study Results:

• Analyze data
• Determine statistical significance
• Extract learnings
• Decide: Scale, iterate, or kill
• Document insights
