What is the 'Iron Law' of this PM skill?

The Iron Law dictates that no specification can be created without a clear, evidence-grounded problem statement and measurable success criteria.

What framework does it use for user stories?

It follows the INVEST framework, ensuring stories are Independent, Negotiable, Valuable, Estimable, Small, and Testable.

How does this skill help prevent scope creep?

The skill mandates a 'Non-Goals' section in every specification to explicitly define what is out of scope, preventing secondary features from bloating the project.

Can I use this for technical specifications?

While focused on product requirements, it includes sections for technical considerations and constraints, making it an excellent bridge between product and engineering.
