What is the sunk cost fallacy in software development?

It is the tendency to keep investing in a failing feature or project simply because significant time and budget have already been spent, even when a pivot would be more beneficial.

Why use Claude for sunk cost analysis?

Claude acts as an objective, third-party analyzer that isn't emotionally attached to the 'blood, sweat, and tears' of a project, making it easier to identify irrational decision patterns.

Can I use this for career or team management decisions?

Yes, the framework is domain-agnostic and helps remove emotional bias from any scenario where prior investment clouds rational forward-looking judgment.

What are 'Kill Criteria' in this context?

Kill criteria are pre-defined, objective metrics established at the start of a project that trigger an automatic re-evaluation or shutdown if they are not met, preventing emotional over-commitment.

How does this skill help with project pivots?

It provides a step-by-step framework to ignore past expenses and evaluate 'pivot or persevere' decisions based purely on expected future returns and opportunity costs.
