Discipleship Model Simulation

The aim of this model is to understand the growth in maturity of church members from conversion to leadership though a discipleship process. The model explores the extent to which an individual congregation "grows" its workers and leaders from its own recruits and converts. The model quantifies the number of people at each discipleship stage, how many progress stages each year, and transfers into and out of other congregations.

The model was developed with system dynamics and implemented in "Stella" produced by ISEE Systems. The online simulation is hosted by Forio Simulate.
