Framework Thinking｜Scale It 1-100

The "Scale it 1-100" mental model is a simple and effective tool that can be used for decision-making and assessment processes. It involves rating or evaluating a concept, situation, or decision on a scale from 1 to 100. This model brings objectivity into subjective matters, making complex evaluations more tangible and more accessible to communicate. For instance, instead of vaguely determining how confident you feel about a decision, you can rate your confidence on a scale of 1 to 100. This model is instrumental in business and personal decision-making for clarifying and communicating the degree of certainty, priority, or importance of various options or opinions. The following are some examples:

• Rating (1-5): We use a lot of ratings when we buy books on Amazon, visit restaurants suggested by Yelp, and pick up travel services listed on TripAdvisor. People are used to using 1-5 to rate services or products. We also see this used for performance reviews at work. It's a popular use of this thinking framework.
• Progress (1-100): When measuring progress, we use a scale of 1 to 100, where 100 represents completion, and the rate indicates our progress. 
• The Net Promoter Score (NPS 1-10) is a metric used to measure customer satisfaction levels. To calculate the NPS, customers are first asked to rate their experience on a scale of 1-10. Based on feedback, customers are then categorized into three groups: Promoters, Passives, and Detractors. Promoters are customers who rate their experience 9 or 10, indicating that they are delighted and likely to continue using the product or service. They may also refer new customers. Passives are customers who rate their experience 7 or 8, indicating that they are satisfied but need strong loyalty and may need to provide references. Detractors are customers who rate their experience 0-6, suggesting that they are unhappy and may negatively impact the product or service adoption. The NPS is calculated as the percentage difference between the promoters and detractors (NPS = % Promoters - % Detractors).
