Motivation – To initially test a new integrated mission planning process (IMPP) designed to allow echelons of command to collaborate while working distributed through the use of a collaborative mission planning system called MissionMate (MM). Research approach – Case-study approach with observations and questionnaires. Findings/Design – The process and technology (IMPP+MM) worked despite a minimum initial training effort. Problems to be addressed in follow-up studies are: To establish a minimum system proficiency level among users; to create a mindset among staff officers allowing true collaboration across echelons of command, and to accept distributed collaboration as a norm instead of face-to-face meetings. Research limitations/Implications – This was the first of several planned studies to develop IMPP+MM. The qualities of the new approach have not yet been assessed experimentally. Take away message – The IMPP+MM model has potential to increase the effectiveness of integrated planning between echelons, both by saving time and increasing shared understanding of the plan.
