Here’s an extract from a great article by the ^[1]Center for Creative Leadership ^[1]:

A research-based, time-tested guideline for developing managers says that you need to have three types of experience, using a 70-20-10 ratio: challenging assignments (70 percent), developmental relationships (20 percent) and coursework and training (10 percent).

The 70-20-10 rule emerged from 30 years of CCL’s Lessons of Experience research, which explores how executives learn, grow and change over the course of their careers.

Does this sound familiar?

Of course, CCL is missing one core dynamic: the spiritual dynamic.

Biblically, we know that there are four dynamics of transformation ^[2]. Nevertheless, this is a very interesting confirmation of our model of leader development ^[3].
