Method Transfer


i am writing a method tranfer protocol to transfer hplc method to the outside contrace laboratory. i am also revising an SOP#xyz of analytical method transfer beacause lots of things in that sop does not make sense.

my question is should i revise and have he method transfer SOP first, then have everyone signed method tranfer protocol ? OR it really does not matter just mention in the mthod transfer report that method tranfer was executed using a revised method transfer sop revision 02.
