Lesson 5 – The intervention matrix In the closing lesson, Thomas Jordan presents the so-called intervention matrix; a blueprint of sorts for various measures and strategies to bring a conflict to end. A worksheet with the intervention matrix is also available to download here. Click the ”back” arrow in your browser to return to the training course. On one side, you can consider a current conflict at your own agency and fill in the matrix. On the other side, there is a completed matrix that will give you a better understanding of how the model works.
