Justification

DESIGN IDEA NO.	OBJECTIVES	SCORE	JUSTIFICATION
1	PORTABLE	--	weighs more than the datum considered
	ATTRACTIVE APPEARANCE	-	its not much attractive when compared to datum
	COST	+	cost less as components are been used less
	INTERACTION AND COMMUNICATION	+	its efficient when compared to datum
2	PORTABLE	0	Datum
	ATTRACTIVE APPEARANCE	0	Datum
	COST	0	Datum
	INTERACTION AND COMMUNICATION	0	Datum
3	PORTABLE	-	as the screen is larger in size it weigh more than datum
	ATTRACTIVE APPEARANCE	-	its simple and components are used less
	COST	+	as it is simple, as it cost less
	INTERACTION AND COMMUNICATION	+	its not much interacted nor communicated as speakers not been used
4	PORTABLE	+	easy to carry when compared to datum
	ATTRACTIVE APPEARANCE	++	the outlook is more attractive than datum
	COST	-	cost lesser than datum, as components used in simple and effective
	INTERACTION AND COMMUNICATION	++	very efficient and effective as speakers and lcd is used
