Realistically it is possible for the process to work, but again it completely depends on your STLs "idea" of what it should look like and/or whoever is doing your store's payroll allocation. The secret to "logistics" success is a micromanagement of payroll since its so tight as is, so when they start pulling payroll out of one workcenter and moving it to another they need to know realistically how much payroll it should take to do certain jobs and assign those duties to the team...
For example, ours pulled hours out of Unload and into Market, but didn't pull enough to get the FDC worked as well (so they struggled to figure out whether or not to run dairy or dry first).
I personally want to tackle it as a pilot again (but I suppose the live version would do) but I would highly recommend doing a mock schedule in excel if I were the STL and figure out EXACTLY who is doing what and how many hours each job should take before just swinging hundreds of hours between workcenters around.
