5.1 JUSTIFICATIONS FOR SCORE GIVEN

DESIGN.NO	OBJECTIVE	SCORE ALLOCATED	JUSTIFICATION FOR SCORE GIVEN
1	Automatic	8	The design is automatic as the device automatically stamps the paper.
1	Compactibility	-5	This design is not compact because it is very huge.
1	Portability	-3	This design is not portable due to its heavy weight.
1	User Friendly	4	User can easily operate the device.
1	Cost	-3	The device is bit costly to make.
2	Automatic	DATUM	This design is used as Reference design.
2	Compactibility	DATUM	This design is used as Reference design.
2	Portability	DATUM	This design is used as Reference design.
2	User Friendly	DATUM	This design is used as Reference design.
2	Cost	DATUM	This design is used as Reference design.
3	Automatic	8	This design is Automatic as it does not require any manual work.
3	Compactibility	-5	The design is not compact since the wirings can be seen and its kind of naked design.
3	Portability	-3	The device is not portable as it has heavy weight.
3	User Friendly	8	The design is very user friendly since there is no work to do by the user.
3	Cost	-3	The design is a bit costly comparing to the other designs because it need advanced parts to make it.
4	Automatic	8	This design is Automatic as it does not require any manual work.
4	Compactibility	-5	The device is larger in size and requires more space.
4	Portability	-3	The device is not portable due to its large size.
4	User Friendly	8	The device can easily be operated by the user.
4	Cost	3	The device is less costlier compared to other designs .
5	Automatic	8	This design is Automatic as it does not require any manual work.
5	Compactibility	-5	This design is not compact as it has long conveyer belts.
5	Portability	-3	This design cannot be ported anywhere due to its huge size and weight.
5	User Friendly	4	User can easily operate the device.
5	Cost	-3	This design is not cost efficient as it requires huge conveyer belts and motors.
