Having had people selected for IDC active and reviewed application on those selected for DCO it is quite different.
AD looks for good base to build on such as good degree/GPA, community involvement, LOR's that talk about good work ethic and such.
DCO looks for track record (10 years) of industry experience and significant management/supervisor experience.
Prior to taking on his new job, someone at my command asked Admiral Rogers about the selection rate for enlisted-to-commissioning programs on the IW side. His response was kind of surprising:
Admiral Rogers said that he had hoped to see more prior-enlisted officers go the distance, i.e. 30 years of service en route to a command position, but has seen many reach 20 and retire as O-3's and O-4's. For this reason, he said believed that boards might be more apt to select folks from the civilian sector; even if they only did 20, they would provide a full 20, whereas someone with 10 years enlisted would be halfway there.
I'm paraphrasing, and probably missing some other important points, but this convinced me to repeatedly state my intent to pursue leadership (and eventually command) positions, as well as extended service.
I have no idea whether or not this has been reflected in past selection results, but I believe this falls inline with the "base to build on" that you've mentioned above. It should also give those in the civilian sector a little more hope.
