The model is Acts Academy's 5K growth model, and the seven growth inhibitors are Acts Academy's own. The texts are Mark 4, 1 Corinthians 4:20, Acts 1:8 and 6:1-4, Romans 12:2, Hebrews 12:15, Ephesians 4:3 and 4:31-32, Matthew 12:25 and John 17, quoted from the World English Bible.

The method draws on Christian A. Schwarz and Natural Church Development. Four things from it are built in: the minimum factor, the eight quality characteristics, the six biotic principles and repeated measurement over time. The six statements marked NCD cover the quality characteristics the 5K model does not hold on its own.

Two cautions. The statisticians John Ellas and Flavil Yeakley criticised Schwarz's study for not being replicable and for presenting correlation as cause. The minimum factor survives that criticism, because it is a rule for prioritising and not a measurement. And this test does not norm: Schwarz norms to 50, but that norm is country-specific and there is no Danish norm group.
