I like #29 and #27 as concepts. You've incorportated the vee model, and arrows to show process. #27 and #28 do not show the top return arrow to show the "validation" phase, and the gradation lines in the middle are upside down, since in systems design, the system goes from larger chunks to smaller chunks. In #29, I would like to see the bottom of the vee smaller, and the return arrow tip hit the left side of the vee.
Hi sbilen I've made the modifications requested. Do you think we can lose the arrow on the bottom? It's the timeline and the flow of the process remains in the V model without it. Also it might look better
