4.3 Justification for marks given to the Concepts/designs

Design Number	Objective	Score Allocated	Justification for score allocated
1	Reliability	18	Design 1 is more secure than datum as all its electronic circuits are hidden inside the locker and so it can't be manipulated and it also has loud alarm .
	Portability	7	The design 1 is more portable as its components are tightly intact inside locker which makes it easy to carry and also it is operated on battery
	User-Friendly	14	The design 1 is much more easy to use and configure than datum due to its simple numeric keypad,which everyone can understand and everyone can easily setup
	Automatic	0	Both the designs have same level of automation in them

Design Number	Objective	Score Allocated	Justification for score allocated
3	Reliability	-9	Design 3 is less secure than datum as all its electronic circuits are not hidden inside the locker and so it can be manipulated
	Portability	7	This operates on battery unlike Datum and design 4 which makes it more portable and carriable anywhere
	User-Friendly	0	Design 3 and datum both has same level of user friendly
	Automatic	6	It has almost all the processes automated unlike datum,example automatic lighting after opening door and switching off of light after door closed

Design Number	Objective	Score Allocated	Justification for score allocated
4	Reliability	-18	Design 4 is very less secure than datum as all its electronic circuits including batteries are not hidden inside the locker and so it can be manipulated
	Portability	0	Same level of portability as Datum
	User-Friendly	7	More user friendly as it can be unlocked using just a touch of fingerprint
	Automatic	0	Design 4 and Datum both has same level of automation
