In order to solving the issue that describing large complex information system for better, operation capability views based on DOD Architecture Framework (DODAF) are researched. Referring to the concept of DODAF and combined with the fact of our army, the summary of operation capability views is put forward. Inner relationship of operation capability views is analyzed. Operation capability views are implied in generating of operation capability requirement for analyzing and describing operation capability system. The example demonstrates that operation capability views can support creating the scheme of operation capability requirement effectively. The method also supports for analyzing further requirements and generating program.
