Interagency education, training, and assignments?

Concerning interagency assignments, training, and professional education... what are your thoughts and opinions? How are we currently doing in these areas from the DoD perspective? What are we doing right and what could we be doing better? Is the next logical focus for inter-government cooperation and integration be in the interagency realm? Since the Goldwater-Nichols Act of 1986 the military services have made strides in "organizing, training, equipping" across the joint spectrum; similarly, if the inter-agency push calls for wide-spread focus on integrated professional education (training, exercises, assignments, etc.) how are we doing in this area thus far? What grade would you give the interagency effort in-progress? The idea here is to draw attention to the issue and to discuss, brainstorm, and problem-solve interagency professional education (and related topics) in order to create synergy, foster professional relationships, enhanced knowledge of capabilities and processes, and cross-agency SA. We have a thoroughly experienced and highly capable audience, therefore I'm sure that this will be an informative and enlightening discussion; so, let's get things started; thank you for all that you do, and... see you all in the discussion threads!
