# Product

> **From severe-weather intelligence to prioritized, auditable action.**

StormTrust turns forecast, radar, observed, property, operational, and campaign intelligence into an auditable answer to seven questions:

1. Where is severe weather likely?
2. What does radar indicate is happening?
3. What was actually observed or reported?
4. What geographic area was probably impacted?
5. Which properties were probably exposed to damaging hail?
6. Where should people deploy, and who may be contacted?
7. What action was taken, and what happened afterward?

The complete product lifecycle is:

The product model requires each transition to remain understandable, attributable, and reproducible.

## Documentation index

Each subject hub links to its tutorials, task guides, reference, and explanations. Read [Applications](/stormtrust/apps/) for implementation boundaries and [Operations](/stormtrust/engineering/operations/) for executable procedures. The [release roadmap](/stormtrust/product/strategy-and-reference/release-definition-and-roadmap/) records requirements rather than deployment status.

## Product definition

StormTrust succeeds when it preserves a defensible chain from uncertain atmospheric signals to measurable outcomes. The chain, not the map alone, defines the product.
