Rolediffer

Rolediffer is a term used in sociotechnical research to denote the process or result of measuring differences between roles within a system. In practice, rolediffer refers to a formalized framework for comparing the attributes, responsibilities, and interactions associated with distinct roles, such as job positions, team functions, or moderation duties.

A role is represented as a feature vector in a multidimensional space. Dimensions may include permissions, decision rights, required skills, task types, reporting lines, and interaction patterns with other roles or actors.

Rolediffer employs dissimilarity or distance measures to compare pairs of role vectors. Common approaches include Euclidean or Manhattan distances for numeric features, cosine similarity for directional information, and Gower distance for mixed data types. The process typically involves data collection, normalization, and often clustering to identify role groups and boundaries.

Applications include organizational design, role mining, and workforce analytics. Rolediffer can help identify gaps, overlaps, or redundancies in role definitions, analyze how roles evolve over time, and inform governance or policy decisions in both human and software systems.

Limitations include dependence on the quality and scope of input data and on the chosen feature set. Results can be sensitive to feature engineering and context, and dissimilarity does not always map directly to practical incompatibility or value.
