While I see everything Scot has mentioned I am not sure it is flat rate that encourages part swapping. That unfortunately sounds like something a parts person would say, as if the vast majority of techs are out there just hanging parts to make the parts dept's life miserable. (And I've read a ton of Scot's stuff in the forums and newsletters, so I know that isn't where he is coming from ... just my thoughts.)
Every tech I've ever met wants to diagnosis the problem and get it right the first time - maybe I've just really fortunate in the last 20 years of this business. They don't because (1) management fails to collect on the diagnosis time, (2) the tech is overbooked and when push comes to shove must get the vehicle out or (3) the shop fails to hold techs accountable for comebacks. All three of those issues are management issues - not a problem with flat rate.
I guess I always think of this debate just like every other pay plan debate in the shop - that is management wanting to figure out how to manage through pay and not through shop controls. In this debate (and I am absolutely not saying this is what Hoser was after), I often basically read it as a manager saying, "I can't figure out how to make these guys more productive, so let's flip them to flat rate and let them figure it out for me."
As Scot added all these things are the responsibility of management to control. Incentives based on hours flagged, usually either a dollar amount (flag 40 hours get $75) or a retro-hourly bonus (flag 40 hours make an extra $1 an hour) are common. I personally also like a shop bonus (if our five techs book 200 hours this week) as a teamworking incentive, and then I tell the manager to get to work to make sure the guys can actually do that (scheduling, etc.)
