Let me make you understand the development & drawing & design direction of BSM more clearly.
In the very beginning we (HAC-ID & HAC-AO) Jointly Prepared the Planning drawing of BSM in which installation location was considered at the center line of Door but due to very high cost of BSM HAC-ID proposed to reduce the part thickness from "9mm to 5mm" .
HAC-AO check the HAC-ID cost down idea and checked the layout at 5.0 MM thickness and proposed "Five No of designs" and mutually HAC-ID (DEV+PP+SP) & HAC-AO agreed the "Design-5" During TV meeting and requested HAC-AO to incorporate "Design-5 in C1 drawing".
HAC-AO shared the part dimensions to HAC-ID on 12-Feb'15 to check the cost from supplier and at P2 final evaluation on 28-Feb'15 HAC-ID Proposed the cost and got its approval from management. as per below snap shot and moreover cost which was shown shown at P2 final evaluation dated (28-Feb'15 ) was based on just Part dimension shown by HAC-AO and without 3D data as our supplier had estimated as per Dimensions only and HAC-ID was exptecting to get the 3D data as per design-5 at C1 drawing issuance timing.
Now at C1 drawing issuance timing Drawing direction was changed and was not informed to HAC-ID , on 02-May'15 we had meeting with our supplier to estimate the cost as per C1 drawing and once we get the cost we will let you know.
If C1 drawing cost is same as P2 shared cost dated (28-Feb'15) , then HAC-ID will stick to C1 drawing design for Tool Go, but if cost is higher than P2 shared cost then HAC-ID would like to go as Per design-5 for Tool Go drawings otherwise we will have to separately report to HAC-ID management for cost approval.
