Does the sector matter?

Some productivity methodologies and techniques seem to be more used in specific sectors. 

This suggests that either they are in some way particularly suited to the processes involved in that sector …. or perhaps just a historical accident that the methodology or technique started in that sector and has not yet broken our into wider industry.

My view is that all techniques are applicable in all sectors … especially since most of them are simply structured ways of asking searching questions.

So, because a technique seems to be well-established in a particular sector doesn’t mean you shouldn’t transfer it to your own sector.  After all learning from others is always a useful approach.
