Abstract

Purpose

The purpose of the paper is to develop a mathematical model that describes group learning processes with and without worker turnover.

Design/methodology/approach

Based on an extensive literature review, fundamental characteristics of group learning processes are first identified and then incorporated into a group learning curve (GLC). The developed GLC is then validated by fitting to empirical data.

Findings

The results show that the behaviour of the developed model is in conformance with the characteristics identified in the literature. A comparison with two other learning curves that have frequently been discussed in the literature shows that the GLC developed in this paper is a good mathematical representation of group learning processes.

Practical implications

The model developed in this paper enables practitioners to predict performance improvement in groups.

Originality/value

The paper is one of the first to propose a mathematical formulation of a GLC.
