DoD SE Acquisition RequirementsDefinition Challenges Good requirements definition practices are core to goodsystems engineering– Current DoD guidance needs to be strengthened: e.g. Better application oflogical architecture approaches– Too often the contractor does the transformation from Capabilities toSystem Requirements incurring latent discovery of issues and risks– Congress is demanding the definition of Technical Parameters and beingverified by DT&E Current Systems Engineering Plan Guidance– No emphasis on CONOPS development or Mission Analysis: A key enablerfor good system requirements analysis– Too much emphasis on requirements management but not enough onrequirements analysis approach NDIA identifies requirements as one of its top issues:– “Requirements are not always well-managed, including the effectivetranslation from capabilities statements into executable requirementsto achieve successful acquisition programs.” (2006 Task Group Report: TopFive Systems Engineering Issues Within DoD and Defense Industry)13th Annual NDIA SE ConfOct 2010 Page-4DISTRIBUTION STATEMENT A -- Cleared for public release by OSR on 08October 2010 -- SR case number #11-S-0075 applies.

The US DoD has two PKI: DoD PKI is their internal PKI; DoD ECA PKI is the PKI for people outside of the DoD [External Certification Authority] who need to communicate with the DoD [i.e. you]. Fortunately, the DoD has created a tool for Microsoft to Trust the DoD PKI and ECA PKI; the DoD PKE InstallRoot tool.File Size: 1MBPage Count: 10
The DoD PKI consists of the US DoD issuing certificates internally to US DoD end entities (like DoD employees and DoD web sites). The ECA PKI consists of vendors that are authorized by the US DoD to issue certificates to end entities outside of the US DoD that need to communicate with the DoD. You probably need to trust both the DoD PKI and ECA .
