A Marimekko chart provides a great visual for your current sales pipeline. If you sell large deals, represent each as a segment in the chart. The bars are the pipeline phases. Use the "Other Series" to group smaller deals into one category. The chart below represents software services sales:
I added two data rows to the chart to track average deal size for each pipeline phase and number of deals in each phase. A sales manager can look at the chart to identify deals that need attention or to work with sales staff to add deals to or move deals through the pipeline. If your sales pipeline is made up of many smaller deals, they can be grouped by industry or product.
