Back to Mental Models

The 80% Completion Problem

Pattern where builders using new tools get 80% of the way to completion but abandon projects due to specific technical roadblocks

Decision Rule

When evaluating tools or building services, consider what happens when users hit edge cases the tool doesn't handle well

How It Works

New tools excel at common use cases but struggle with edge cases, leaving users without clear next steps when problems arise

Failure Modes

Assuming tools will handle all edge cases automatically

Underestimating the support infrastructure needed around new tools

Focusing only on initial user experience without considering completion rates

Example Decision

Before choosing a no-code platform for clients, research what support options exist when the platform's limitations are reached
