This is the first user experience metric that is comparable across all transactional applications â€“ a value of 0.85T means the same thing in all applications even with different values of T. Thus, the enterprise manager has a single measurement to compare performance across applications or other reporting groups.
This is the one-number metric that senior management can easily understand and use to manage IT across many applications. Managers can quickly see which applications need improvement or investment, those that have a low Apdex value but are important to the business.
Apdex also lets enterprises measure the effectiveness of performance improvement investments. An Apdex value should improve with a performance-driven upgrade. Apdex will focus attention on applications that need remedial investment and show whether the investment paid off.
CIOs call these their top three goals:
- Increase business efficiency through IT-enabled process improvement.
- Align IT and business goals.
- Improve internal customer satisfaction.

Apdex improves CIO’s ability to achieve all these goals.
The vendors that are members of the Apdex Alliance will supply Apdex features in upcoming releases of their products. In each case, the cost of adopting Apdex will be very modest. There is no new fundamental technology, product, or service that needs to be purchased. Enterprises will be able to use Apdex reports as soon as the upgrades are installed.
Apdex values fall between 0 and 1 where, 0 means that no users are satisfied and 1 indicates that all user samples were in the satisfied zone. Clearly, a higher number is better. But not all applications will achieve or need to receive a perfect value of 1. The Alliance has developed a simple rating scale that provides a quick assessment of an application. The ratings, along with Apdex values that define them are shown below.
