Delta Health Score

What is the Delta Health Score?

The Delta Health Score indicates how well your project is running in real time. This letter grade combines the level of feature coverage your project is getting (based on audience engagement) with the amount of actionable feedback submitted by your audience. Your project's Delta Health Score gives teams a confidence range on the Delta Success Score for their product, feature, or service. The higher the health score, the higher the confidence and accuracy of your Delta Score.

Why is the Delta Health Score important?

Traditionally it has been difficult to understand if projects are doing well or poorly. Even harder when it comes to comparing them to other projects being run within an organization. This simple metric allows the team to clearly understand how well the project is performing from a feedback and engagement perspective. 

By using the delta health score, you can see benefits such as:

• Benchmark project health score to continuously improve program processes
• Provide a confidence in the product metric for Delta Success
• Performance indicator for the project manager running a delta test
• Identifies if more testers or more feedback is needed to increase confidence
  

How do you calculate Delta Health Score?

The Delta Health Score calculation takes the product, the test audience, and the amount of engagement within a project into consideration. It calculates how much engagement you need in order to have confidence in your results, compared to how much engagement you have at the moment.

There are two components to the actual Delta Health Score: Activity Engagement & Feedback Engagement. Each one accounts for 50% of the total score. A good Delta Health Score (above 80%) indicates high confidence in the results you're collecting.

The experimental nature of the Delta Health Score

There are still lessons to be learned about how engagement ultimately influences a project and product. Factors such as your target audience, product readiness, and influence from test admins can all affect your Delta Health Score. But while it is an experimental metric, it's still a beneficial tool for understanding your project and its impact on making your product better.
