Tee Emm,
Right on! So far, it works fine for me, after a little period of adjustment.
Change of old habits is always a bit painfull, but smart people have been working on this for a long time as a response to several events where a checklists was responded to and the items to be checked were in the wrong position.
Now, instead of an Abott & Costello duet like checklist, where one pilot reads a litany and the other shoots back the responses, sometimes regardless of the item to be checked, each CM is to insure that the items in his area of responsibility are in the proper position (Exception made or the three phases mentioned earlier) the other one being somehow more compelled to look that the challenge AND the response are correct and in accordance with the item's position. Give it a chance, and we'll see how it works.
