Why would the FSO check the box?
There is the poor practice of candidates allowing (or being required to allow) others to type the security questionnaire (eQIP) responses for them. Even when I am told about this practice, and this is more common than many realize, you, the Subject, are still responsible for the information on the questionnaire - and you sign a declaration that it is true and complete.
Too much time is spent during the Subject interviews correcting the eQIP responses because Subjects, FSOs, companies, and federal agencies, treat the questionnaire as a burden. Missing information, poor information, incomplete information all add to your clearance delay.
Every time I am given the opportunity to brief security managers or FSOs, I stress the importance of completing the security questionnaire thoroughly, thoughtfully, carefully, and completely.
If you knew you were going to have a full audit from the IRS, would you only spend 30 minutes gathering information for your return and 30 minutes to fill out the return? Or would you do all the research yourself, check your work, and ensure everything was correct before you signed and submitted that return?
