The experiment design phase: Create a new experiment

The decisions you make in the design phase set the stage for your experiment’s success. By putting more thought into your experiment’s purpose and goals before you start, you’ll be far more likely to glean useful, actionable insights from it.

To create a new experiment, first ensure you’ve created an environment and installed the SDK. Then follow these steps:

1. Open Amplitude Experiment and click + New. From the drop-down menu, select Experiment.
2. In the Create Experiment modal, choose the project that will house this experiment from the Projects drop-down menu. 
3. Amplitude Experiment uses flags to include experiments within your product. In the appropriate fields, give your flag a name and a description. Experiment will automatically generate the flag key for your experiment from the name you choose; this key will act as an identifier for the flag used in your codebase.
4. When you’re done, click Create. Experiment will open a blank template for your flag.
5. The first step is adding context to your experiment. The Context panel is an Amplitude notebook template that gives you a space to explain the objectives, target audiences, and goals of the experiment for stakeholders and other members of your team. This means that anytime another person views your experiment, they’ll be able to understand it at a glance.
   
   
   To fill in the Context panel, click Add Context. Click into a field to edit it.
   
   NOTE: Filling out the Context panel is not required to run an experiment, but it’s strongly recommended.
   

Next, you'll create and add your experiment's success metrics.
