What is the difference between a core value (Kernwert) and a value quality (Wertqualität)?

A core value is one that stakeholders name or describe again and again and so carries special weight; value qualities are the concrete aspects in which the core value shows itself, and each one can strengthen (+) or threaten (−) it.

VbE handles the many values stakeholders mention by clustering them:

• Core values should be phrased positively, wanted for their own sake and valid across cultures (knowledge, security, privacy…).
• Value qualities can be values themselves. IEEE 7000 calls them value demonstrators: the core value "shows itself" in them.
