WCX as global reference standard
WCX provides a subjective quality reference across networks of all suppliers and all kinds of customer groups and across the 20 major countries in the world.
This reference is taken to ensure a possible bias in quality data. This policy is supposed to distinguish between a local and a global optimum. Examples of sources of a bias:
- Measures are taken only in the environment of a single network. Some of the results cannot be generalized
- Our feedback base suffers from a kind of structural bias that distorts results (e.g. a high percentage of low-level devices in the network)
The reference measure is especially important when it comes to estimate the economic value of an action, a functionality, or any improvement measure.
