Narrative:

Denver TRACON has opted to implement new procedures to fix overshoots on the 16 runway finals. At any given time one of the 16 finals is called the 'high' runway and is told to conduct ILS approaches while the other is the 'low' runway and is told to conduct visual approaches. However here at denver we also have RNAV zulu approaches which is an instrument approach that arcs to the runway from the downwind. It was decided that I was going to go from being the 'low' runway to being the 'high' runway. Unfortunately this was never coordinated with me I had to figure it out myself based on how I was being fed. As I began to transition the volume picked up and I was focused on meeting the requirements put forth by management that super-exceed the 7110.65 for separation. As I began to run the final and get all of the aircraft onto the ILS I noticed an RNAV zulu approach within 3 miles of the aircraft I had cleared for the ILS. I issued the visual approach clearance to the aircraft but at that point it was already a loss of separation. There are 3 clear options to resolve this from happening again or to another controller. The first is to remove the procedures and return to working traffic as we had previously. The FAA has taken the responsibility of the pilots and the airlines and taken it upon themselves to fix a problem with procedures that are ineffective and damaging to the NAS. The second is to explain to the tower and the airlines that for safety we will now be landing on runway 17L and 17R which has more space between finals. Finally the last is to once again refine the procedures; create new stars that will allow for the smooth operation of these procedures; and properly train the workforce rather than rushing out the procedure so local management can collect data.
