concluded: gms global vdp lead times lag toyotas by several months toyotas enablers: decoupled development, overlapping functional work and fast functional processes dsi to sorp advantage of about 4 months gmdat lean vdp faster for in-country products actual gvdp 5.0 reduction is 15 weeks (37/20 to 33/20) for new and major vehicle programs. reduction moves single theme math 15 weeks closer to the market. gvdp 5.0 was released for programs with a document of strategic intent (dsi) on or after june 1, 2006, and for select programs earlier existing 4.1 programs will not be updated to 5.0 logic or timing. additional studies are being conducted to develop shorter templates for derivative programs gvdp pre-vpi released for use on 06mar06 creates deliverables important to executing gvdp 5.0,gvdp 5.0 release announcement 07april 06,all, following an initiative sanctioned by the global product development council (gpdc), global engineering leadership team (gelt) and global joint engineering and manufacturing staff (gjems) to shorten product development lead time, we are pleased to announce the release of the global vehicle development process (gvdp) 5.0. this release improves vpi-sorp timing, for new and major programs, from 37 months to 33 months, and moves styling 15 weeks closer to market introduction. gvdp 5.0 is directed at programs with document of strategic intent (dsi) dates after june 1, 2006, and several select (slightly earlier) programs where partial implementation will occur. regards, rick spina executive director global program management,gvdp 5.0 framework

weeks preliminary styling data (psd) & theme approval (ta) have been removed why has it changed? enabled by higher fidelity theme at std due to added time between dsi & vpi idr/vdr work stream consolidation now aligns more closely with interdependent surface development single idr and proximity of dso and sf eliminates need for psd theme approval not a separate milestone and essentially occurs at dso. final design reflected in sf 4 weeks later what does this mean to program teams? earlier decisions required (relative to vpi) to support earlier styling critical sourcing less time between std and sf reduces the opportunity for iterations, reducing the program teams ability to make changes post dso less potential change after idr since panels are developed simultaneously before
