By means of two different user groups (e. g. two different call center agents) the voice compass gives tips concerning the application of certain products and services.

Different exemplary systems are being looked at in a calculatory and costing-based manner for diverse user groups. For this, the compendium always refers to the competition or to alternatives.

The voice compass shows which points (e. g. service and hosting) have to appear with how much emphasis in a calculation and  it offers rough templates for own considerations as regards to content and calculation.
