Justifications for the score given

Design Number Objective Score Allocated Justification for the Score
1 User friendly -9 As there is no support is provided to punching tool
Working 24/7 7 It is easy to use because it starts working after sensing the paper
Portability -12 It is long in shape and has more mass
Semi-Automatic 5 It takes less time to complete the operation as we have to place the paper directly at workpiece
Cost 4 The materials required to build it are less costly
Aesthetic design -3 It is simplistic.
2 User friendly 0 Datum
Working 24/7 0 Datum
Portability 0 Datum
Semi-Automatic 0 Datum
Cost 0 Datum
Aesthetic design 0 Datum
3 User friendly -9 It is not prone to any injuries as it is automatic and the person's hands stays away from the machine
Working 24/7 7 It is easy to use because of its automatic nature
Portability 6 It is comparatively shorter then datum
Semi-Automatic 5 As the operation takes less time
Cost 4 It is cost effective
Aesthetic design -3 It is not that much Simple in nature.
4 User friendly -9 It is prone to any injuries as it is semi-automatic and the person should be aware of chain
Working 24/7 7 It is not easy to use because of its automatic nature
Portability -12 It has more mass
Semi-Automatic 5 The punching operation takes more time
Cost -4 The materials required to build it are not costly
Aesthetic design -3 It is Simple in nature.
5 User friendly 0 Though the person's hands will be near the machine,It is adequately safe
Working 24/7 7 It is easy to use .Only placing the paper is enough.
Portability 12 It is small and has less mass.
Semi-Automatic 5 It is very time efficient
Cost 4 The materials required to build it are not costly
Aesthetic design 6 It is good
