Zoned Analysis: A Middle-Out Method to Join the Top-Down and Bottom-Up Approaches DuringMission Analysis

摘要

Zoned analysis (ZA) is a decomposition methodology, which ultimately evolves intorna graphical “big picture” of a project. This methodology maps the “journey” a systems engineerrnuses during the mission analysis phase to facilitate collaboration of team members, enhancernmanagement understanding of the project, show team members their responsibilities, linkrnrequirements to deliverables, and aid in the gap analysis between what is wanted and what isrntasked. A ZA appears as a bull’s-eye or target with partitioned pie-shaped sections emanatingrnfrom the center circle to outer circles, or zones. The title of the project or program is placed inrnthe center zone. Subsequent partitioned zones facilitate the decomposition hierarchy of thernproject, with the outer-most zones or elements evolving as terminal elements or deliverables.rnThis paper show how a ZA was used to flesh out the details in between top-down and bottom-uprnapproaches during the mission analysis phase.
