Even I was about to exactly suggest what our friend above has suggested. Truly apt suggestion. This model also very clearly and technically explain these concepts. OD books will also contain a few more models on these topics. Both types of leaderships are needed but the emphasis on transformational leadership (change orientation due to ever dynamic external environment) is very important and imperative.
