Pol Probe

To validate product hypotheses before building, define a Proof of Life (PoL) probe to test specific risks cheaply using disposable prototypes. This structured experiment documents your hypothesis, success criteria, and disposal plan to prevent wasted development effort.

A Proof of Life probe in product discovery is a lightweight, disposable validation experiment designed to uncover harsh truths about an idea early. It structures tests for specific hypotheses and risks before committing significant development resources.

Choose the right prototype flavor for hypothesis testing by matching your validation goal to one of five methods: feasibility checks, task-focused tests, narrative prototypes, synthetic data simulations, or vibe-coded probes.

Use synthetic data simulations for risk assessment when you need to validate technical dependencies or complex data interactions without investing weeks in building a real feature. This prototype flavor simulates outcomes to de-risk development decisions cheaply.

Yes, you can use task-focused tests as a Proof of Life probe to check if users can complete a critical task with a mock-up. This validation method quickly tests usability and task flow before actual development begins.

When defining disposable validation artifacts, consider that they require a strict disposal plan and clear success criteria to avoid scope creep. These probes are designed for quick, targeted validation, not as production-ready prototypes.
