The DCMO is responsible for completing and transmitting an Annual Organizational Assessment. The basis for the Department's Annual Organizational Assessment is its annual performance results, pursuant to DoD's Annual Performance Plan and other DoD-wide and DoD Component-specific performance results. Section 4315 of Title 5, United States Code and Office of Personnel Management (OPM) implementing instructions require that personnel evaluations for SES and SL/ST professionals be based on both individual and organizational performance. This is accomplished through the Annual Organizational Assessment. OPM further requires each Agency to describe, at the end of the performance rating period, how it assessed organizational performance and how it communicated that performance to rating and reviewing officials and members of Performance Review Boards to inform individual performance decisions.
