Certifications provide a formal acknowledgment by an approval authority that a system or program meets specific requirements. Certifications, in many cases, are based on statute or regulations and drive systems engineering (SE) planning. Systems Engineering Guidebook, Section 2.4 Certifications, provides a more in-depth discussion on certifications.  The SEP Outline requires programs to provide a certification matrix that identifies applicable technical certifications and when they are required during the acquisition life cycle. Programs should include certification activities and events in the Integrated Master Schedule (IMS) and the Integrated Master Plan (IMP).  A non-exhaustive list of certifications is available in the Acquisition Program Technical Certifications Summary. Additional information on certifications can be found in this sub-topical area.
