Experiment Planning agent
Experiment Planning is an Optimizely Opal agent that transforms raw ideas into a fully formed experiment plan, complete with hypotheses, key metrics, risks, and critical assumptions.
- Challenge – A poorly planned test results in few learnings. Running quality tests means teams can get to deeper learning faster.
- Agent outcome – A fully-formed test plan with hypotheses, metrics, risks, and assumptions.
- Value – Create an experiment plan that enhances your team's overall testing framework.
