Herein are my thoughts and commander's guidance regarding effects-based operations (EBO). This article is designed to provide the US Joint Forces Command (USJFCOM) staff with clear guidance and a new direction on how EBO will be addressed in joint doctrine and used in joint training, concept development, and experimentation. I am convinced that the various interpretations of EBO have caused confusion throughout the joint force and among our multinational partners that we must correct. It is my view that EBO has been misapplied and overextended to the point that it actually hinders rather than helps joint operations. Therefore, we must return to time-honored principles and terminology that our forces have tested in the crucible of battle and that are well grounded in the theory and nature of war. At the same time, we must retain and adopt those aspects of effects-based thinking that are useful. We must stress the importance of mission type orders that contain clear commander's intent and unambiguous tasks and purposes and, most importantly, that link ways and means with achievable ends. To augment these tenets, we must leverage nonmilitary capabilities and strive to better understand the different operating variables that make up today's more complex operating environments. My assessment is shaped by my personal experiences and the experiences of others in a variety of operational situations. I am convinced that we must keep the following in mind. First, operations in the future will require a balance of regular and irregular competencies. Second, the enemy is smart and adaptive. Third, all operating environments are dynamic with an infinite number of variables; therefore, it is not scientifically possible to accurately predict the outcome of an action. To suggest otherwise runs contrary to historical experience and the nature of war. Fourth, we are in error when we think that what works (or does not work) in one theater is universally applicable to all theaters. Finally, to quote General Sherman, Every attempt to make war easy and safe will result in humiliation and disaster. History is replete with examples and further denies us any confidence that the acute predictability promised by EBO's long assessment cycle can strengthen our doctrine. The joint force must act in uncertainty and thrive in chaos, sensing opportunity therein and not retreating into a need for more information. USJFCOM's purpose is to ensure that joint doctrine smooths and simplifies joint operations while reducing friendly friction. My goal is to return clarity to our planning processes and operational concepts. Ultimately, my aim is to ensure leaders convey their intent in clearly understood terms and empower their subordinates to act decisively. While the North Atlantic Treaty Organization (NATO) and many partner nations have adopted the EBO nomenclature, NATO's policy focuses on the whole-of-government/Comprehensive Approach. In short, NATO's effects-based approach to operations (EBAO) does not fully mirror US EBO. Thus I have not addressed NATO's use of EBAO in this USJFCOM commander's guidance. This article explains my perspective and provides guidance on issues related to USJFCOM use of EBO, EBAO, operational net assessment (ONA), and system-of-systems analysis (SoSA) in future force development, training, and experimentation. Elements of these concepts have proven useful in addressing closed systems such as targeting, where their effects can be measured per the US Air Force's deliberate analysis and targeting methods. However, the concepts have been misapplied by others to operations beyond their original intent, resulting in overextension and confusion. Therefore, we will change course and provide the joint warfighter with a more balanced and understandable framework in which to plan, execute, and assess operations. My Perspective After a thorough evaluation, it is my assessment that the ideas reflected in EBO, ONA, and SoSA have not delivered on their advertised benefits and that a clear understanding of these concepts has proven problematic and elusive for US and multinational personnel. …
