This is a very heavy thin book. Packed with distilled information on how to build a learning organization.
The model makes so much sense, and it seems that the short term focus of the past two decades is a major cause of a lot of organization problems. I also like that it mentioned the essential requirement of monitoring the external environment and accordingly be flexible in the execution of your plans.
Understanding this helps you realize why training programs fail and don't get enough support from the management.
I'd strongly recommended this for business owners, directors, HR leaders and OD consultants.
