qualityor

Qualityor is a term used to describe a framework for evaluating and guiding decisions based on quality considerations. It is not a single standard but a family of approaches that aim to quantify quality across products, services, and processes and to integrate this quality measure into decision making.

The core idea is to compute a composite quality score, often denoted Q, derived from multiple indicators such as reliability, performance, usability, maintainability, and conformance to requirements. Indicators are normalized and combined through weighted aggregation; a probabilistic or interval-based model may express uncertainty. The "or" in qualityor reflects the decision logic of choosing paths that meet or exceed quality thresholds, or selecting among alternatives using quality as a primary criterion.

History and usage: The term has appeared in theoretical contexts within quality engineering and decision analytics since the early 21st century. It is primarily used in academic discussions to illustrate how quality considerations can be formalized in multi-criteria decision analysis and risk assessment, with occasional references in industry pilots that explore quality-driven procurement or product design.

Limitations: As a generic term, qualityor encompasses diverse methods, which can lead to inconsistency in definitions and metrics. Successful application typically requires clear metrics, transparent weighting, and robust data collection.
