Is this tailoring..?
Definitely not.. tailoring is not a way to escape from a difficult task.
Tailoring enables one to execute the task via an alternate mechanism instead of the usual procedure. Tailoring doent mean to simply skip the current procedure/process. If the process is difficult , then one must find some other simpler mechanisms to execute the task so that end results are fruitful.
