We have developed a costed and layered Product Timeline and Planning Cube however we still need more work to uncover significant events and hidden facts mined in this paper. In V1 we are still building on those metric layers, and in V2 we are looking for significant events that deploy hidden margins and markers. In V3 we become conscious of events which are not contiguous and which we should ignore. At the Summary level we should attempt to answer developmental questions and to cost significant events within integral layers.
