The best business ideas come from noticing what's working and doing it better, faster, or for a different audience.

One Change Rule

Reusability

A principle that limits innovation to changing only one major element of an existing product or service to maximize probability of success

How It Works

Consumers can only process limited change at once. Changing multiple elements simultaneously creates confusion and rejection. Single changes are easier to understand, communicate, and adopt

Components

1

Analyze existing products/services in your target category

2

Identify the most impactful single element you could change

3

Resist the temptation to change additional elements

4

Focus all innovation energy on executing that one change excellently

5

Test consumer understanding and adoption of the single change

When to Use

When entering established categories, launching new products in competitive markets, or trying to improve existing offerings

When Not to Use

When creating entirely new categories, serving completely different user needs, or when single changes aren't sufficient to create meaningful differentiation

Anti-Patterns to Avoid

Changing packaging, pricing, positioning, and features simultaneouslyAdding complexity when simplicity would be more powerfulAssuming more changes = more value to consumers

Example

Olly vitamins changed only the shape (from round bottles to square) and benefit-focused labeling (from ingredient names to function names like 'Sleep') while keeping everything else familiar.
