"This report describes a concept experimentation assessment of battle command information requirements and military decision making in the 2010-2015 timeframe. This research was the first in a series of concept experimentation programs (CEPs) planned by the Mounted Battlespace Battle Lab (MBBL) at Fort Knox, KY, to re-engineer command and staff operations. This report focuses on research methods, exploratory results, and recommendations on method improvements for assessing battle command information requirements and the military decision making process (MDMP). The exploratory results provide a benchmark for future efforts and suggestions for improving information systems and future evaluations. Limitations and lessons learned on research methods are considered. Method recommendations address measurement approach issues, such as mission, enemy, terrain, troops, and time (METT-T) structure for determining information requirements, and the applicability of the MDMP in a real-time information environment. Recommendations on manual measures address the timing and scope of assessment and respondent workload. Finally, recommendations on instrumented measures stress reducing respondent workload and increasing measurement scope and precision."--Stinet.
