what would put an offer from Release to Hold

If the logic is really simple (a few lines of code), it may be tempting to duplicate the code a few places rather than refactor to extract a method. A few hidden drawbacks --

1) what if the logic changes? have to change several places.


2) even if the logic rarely (never say never) changes, see the email chain below for another reason.


In the re-architecture, it may be worthwhile to have a simple fa├žade method "changeReleaseToHold()", so we can quickly scan the source code (in IDE or grep) to see how many places call it.

Make sure no one could easily bypass this choke point.

Please let me know in case you have a list of such rules which would make an offer go from Release to Hold.
