The Value of 2-Tier ERP for Small and Large Businesses - May 2010
ERP is one of those categories where getting an accurate picture of market share is not that easy. The reason for this is twofold. First it depends on the size of companies; SAP and its closest rival Oracle are most closely focussed on larger businesses, other vendors such as Microsoft and Infor are more focussed on the mid-market - so overall market share does not tell that much. The second reason tying down ERP market share is tricky is that it turns out that large enterprises also buy mid-market ERP products.
