Forrester surveyed 29 vendors of globally deployed banking platforms on their 2012 deals. The results indicate a growing market: We counted nearly 20% more deals in 2012 than in 2011 among firms that we included in both surveys. The top 10 banking platform vendors by volume have the potential to dominate the market, as continuing mergers and acquisitions enhance solution portfolios, strengthen product capabilities, and reshape the market. The risk of rapid change or planned obsolescence in vendors' solution portfolios continues to be a factor that banks must actively consider and manage.
