IDC estimated the size of the worldwide software market for SOA products in the current year to less than six billion dollars. The value should rise to $14 billion up to the year 2011. The competitors of AMR Research put on it still a shovel and included with service revenues also. Therefore companies have spent already $22 billion for SOA projects in 2007\”, writes the German periodical Computerwoche.

Budget managers can do is often the vague term; they require concrete targets and results.
