Dear sir,
Q. 1 What is difference between single loop control and negative feedback control?
I feel both are same as in negative feedback control action is taken to bring back the results towards the plan and same is done ij single loop.
Q. 2.. Sir why these are called single loop and double loop. Does the name suggest something?
Ask the Tutor ACCA PM
Controlling
7y ago#1Both single loop and double loop feedback are negative feedback. Single loop is where the target is not changed, double loop is where the target is changed.
I am surprised that this is in your study text (which I assume is where you found it) because the terminology is not specifically in the syllabus for PM and has never been tested in PM. (I would guess they have simply copied it from the text book for an exam that used to be part of ACCA (but which was removed over 10 years ago) where it was examined!)
O i see.. I found it in bpp text book.
Well thanx for explanation sir
7y ago#3You are welcome :-)
(By the way, single loop is because they only go back ones and try and correct things. Double loop is because having been back once and found that they couldn't correct things, they then go back again and change the target).
