The CSL Review is conducted annually by the Principal Military Deputy (PMILDEP) and approved by the Army Acquisition Executive for CSL positions two fiscal years in advance. For example, the CSL positions rotating out in FY19 were reviewed during the CSL review in FY17. During the review, the PMILDEP reviews and makes decisions on revalidating, establishing, disestablishing, downgrading, upgrading or merging CSL PMs and Acquisition Director Key Billets. Other areas of consideration include, but are not limited to, special qualifications and the need for a military officer versus best qualified (military or civilian) slatee. The AAE is the final approval for all actions decided during the CSL review.
