The LP3 model is a reference and integrative model. In other words, it is not in any kind of competition with other models, which is also one of its strengths. By providing a common code and benchmark, it enables most of the other models to be integrated and in doing so provides them with consistency and additional strength.
It also enables the other models to be understood and implemented more easily.
Approaches such as transformational leadership, transactional leadership, the Malik management approach and a good many other models and methods, to name but a few, therefore take their place in the LP3 model.
