An Improved Effective Cost Review Process for Value Engineering

Table 14

Specification review process for PBA SUB-etc. and CFH.

Idea generation		Specification review
		Step  1	Step  2			Step  3
Category	Idea stimulus question	Specification	Regulation	Who	Why and how	Cost-cutting idea
Form/structure	Can the handset cord be combined with the modular jack?	Separated handset curl cord and telephone body	Unknown	Service	(i) To be easy to repair; (ii) Check the repair rate	〈Form/Structure, Combination, PBA SUB-etc. and CFH (to one piece)〉; The CFH may be directly soldered onto the PCB; Ans1: hard to repair; Ans2: do not apply the idea
Dimension	Can the length of CFH be reduced?	300 ± 20 cm/305 cm	Unknown	Design	(i) Unknown; (ii) Unknown	〈Dimension, Length reduction, CFH_305 cm ()〉; Benchmarking other products; Ans: similar length
	Can the gold plating in the modular handset be made thinner?	15 N-in	Maintains contact resistance after 20 insertions	Design	(i) Unknown; (ii) Unknown	〈Dimension, Thickness reduction, Modular plating_15 N-in ()〉; Ans1: fractures before 20 times if it is less than 15 in; Ans2: do not apply the idea
Component	Can AWG26 be replaced with the same component of a lower grade?	AWG26	Unknown	Design	(i) Unknown; (ii) Unknown	〈Component, Same component of a lower grade; replacement, Wire_AWG26()〉; Ans1: weak signal if it is less than AWG 26; Ans2: do not apply the idea
