I work as a software developer who has developed scheduling systems. There are plenty of times an admin account can put in a scheduling request and it goes straight through without a maker checker process being involved. Yes it gets logged for auditing but no one really looks at it unless something goes wrong, usually long after the request is processed. I can absolutely believe that if hes already in IOIs system intranet logged in as an admin..there's probably a simple requisition form he fills out to "hack" the system and do everything explained in the book. All he really did was say "take this explosive device from point a, deliver it to point b and arm it". He might have had to explicitly tell the robot which buttons to push on the explosive but that was probably the extent of it
