ROSO
ROSO has been previously found to be unworkable. It sounds good on the surface, and initially has some impact, but what happens in reality is that it gives the individual the opportunity to refuse a posting.
ROSO is a two way contract. i.e we will let you fly a BBJ if you promise to stay two years. This may be attractive to some and they will take it. On the other hand, if you have an experienced jet driver who is looking to get out he may choose to reject the ROSO rather than be posted to the wedgetail project because he doesn't need the experience or want to make the commitment.
It happened in all areas in the mid 90's where 2fts instructors were refusing postings to CFS and Squadron pilots were refusing postings to instructors course. In the end it became unmanageable from DPO's point of view, so they scrapped all roso on conversions.
