XYZWerten

XYZWerten is a theoretical framework for evaluating values and outcomes across four dimensions, designated X, Y, Z, and W. Developed in the context of decision analysis and applied ethics, it provides a structured approach to compare alternatives by measuring their performance on each dimension and aggregating these into a composite score. The framework emphasizes transparency in indicator selection and weighting, allowing stakeholders to examine trade-offs between dimensions.

In practice, each dimension has a clear definition, a set of indicators, and a measurement method. Indicators can be quantitative or qualitative, gathered via surveys, sensor data, expert assessments, or documentary analysis. Scores are normalized, typically on a common scale, and combined using weights reflecting priorities or policy goals. The resulting XYZWerten score supports ranking and sensitivity analysis.

Implementation steps include: defining the decision context and objectives; selecting indicators for X, Y, Z, W; collecting data; normalizing and aggregating; and performing robustness checks, such as varying weights to observe effects on the ranking.

Applications range from public policy evaluation and urban planning to product development and corporate risk assessment. The framework is praised for its clarity and adaptability but criticized for potential subjectivity in indicator choice and weighting, which can influence results. Proponents argue that explicit documentation of choices and inclusion of sensitivity analyses mitigate these concerns.
