Simulation with Rule of Three for scale revenue, production or productivity

CalculaTudo: Understand how to simulate scale revenue, production or productivity with Rule of Three before comparing scenarios.

How to use Rule of Three for scale revenue, production or productivity

Allows you to quickly adjust volumes and times while maintaining the correct ratio.

Review Type of relationship, Values A, B and C and Result before comparing scenarios with the calculator.
In the direct rule, increasing one quantity tends to increase the other by the same ratio.
Use direct rule when the problem is inversely proportional.

Relate people and time in inverse proportion

Solve simple proportions with unknown value. Useful for solving direct proportion, solving inverse proportion and scaling revenue, production or productivity.

Recommended inputs: Type: reverse, A: 2, B: 10 and C: 4

Expected reading: The response shows the new expected time when more people perform the same task.

Use this reasoning when the magnitude of effort increases and time decreases.

The result is deterministic based on the choice between a direct or inverse relationship.
The tool assumes simple proportional relationship and does not cover models with extra curves, bands or constraints.

Frequently asked questions

Which inputs matter most in Rule of Three?

Defines whether the proportion between quantities is direct or inverse. Set up the known relationship used to find the fourth proportional value.

How should I read the result for scale revenue, production or productivity?

In the direct rule, increasing one quantity tends to increase the other by the same ratio.

What is the most common mistake when using Rule of Three?

Use direct rule when the problem is inversely proportional.

When should I validate the estimate with another source?

The tool assumes simple proportional relationship and does not cover models with extra curves, bands or constraints.
