5.1 Justification for scores given

Design no	Objective	Score allocated	Justification for the score
01	Ease of use	0	It is easy to use just as the datum
	Ease of portability	0	It is easily portable because of compact size like the datum
	Indicating machine On/Off	0	It has indicator similar to datum
	Works 24/7	0	It can work for 24 hours
	Semi automatic	0	It is semi-automatic since paper has to be put as input from user
	Safety	0	It is safe to use just like the datum
	Cost	-	It is little costlier than datum
	Aesthetically pleasing	0	It is aesthetic like the datum
02	Ease of use	+	It is easier to use compared to the datum
	Ease of portability	--	It is not easily portable because of it's bigger size
	Indicating machine On/Off	-	It does not have indicator
	Works 24/7	0	It can work for 24 hours
	Semi automatic	0	It is semi-automatic since paper has to be put as input from user
	Safety	-	It is less safer to use because of it's open design
	Cost	0	It costs same as the datum
	Aesthetically pleasing	+	It is aesthetically pleasing
04	Ease of use	+	It is easier to use compared to the datum
	Ease of portability	--	It is not easily portable because of it's bigger size
	Indicating machine On/Off	-	It does not have indicator
	Works 24/7	0	It can work for 24 hours
	Semi automatic	0	It is semi-automatic since paper has to be put as input from user
	Safety	-	It is less safer to use because of it's open design
	Cost	-	It is costlier than the datum
	Aesthetically pleasing	+	It is aesthetically pleasing
