Last fall I introduced the “vector space” model of visualizing vendor performance. It shows performance along two dimensions: market share growth vs. profit share growth for a set of competitors.
When introduced, I chose a long time frame (15 quarters) to see the long-term pattern. This quarter I add two more time frames: year-on-year and sequential. This allows a view of how market change is itself changing. The three diagrams are shown below (note difference in scales)
