5.2 JUSTIFICATION FOR GIVEN SCORE:

DESIGN SERIAL NUMBER	OBJECTIVE	SCORE	JUSTIFICATION FOR SCORE
1	User friendly	0	The ease of usage is same as DATUM
	Weight of machine	+6	The mechanism weight more
	Aesthetic looks	+4	The design looks aesthetically good
	Simple mechanism	-4	The mechanism involved is complex and repair require skilled person
2	User friendly	2	The usage is better than datum DATUM
	Weight of machine	+3	The slider and box weight more compared to DATUM
	Aesthetic looks	+3	The chain and sliding mechanism have different looks
	Simple mechanism	+4	The mechanism complexity is same as DATUM
3	User friendly	0	DATUM
	Weight of machine	0	DATUM
	Aesthetic looks	0	DATUM
	Simple mechanism	0	DATUM
4	User friendly	+2	The usage is simple and easy
	Weight of machine	-3	The weight of machine is more than DATUM
	Aesthetic looks	+2	The cylinderical shape is gives Asthetic looks
	Simple mechanism	+1	The mechanism is simple and require minimum component
