Experience and consulting expertise asked Munich – IT analysts outdone himself in recent years with huge market forecasts for so-called service-oriented architectures (SOA). 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. At an average annual growth rate of 20 percent, the market volume may rise to up to nearly $52 billion by 2012. At least 77 percent of all companies should have launched until then an SOA initiative. It is believed the augurs, the motives for SOA are always the same: sinkende more agility in the competition through more flexible IT structure, a more efficient IT operation thanks to reusable services and to the bottom line Cost\”, so the German periodical Computerwoche.
However, that stand in stark contrast to the practical experience of which consultant report. Most SOA projects will fail spectacularly\”, warns Anne Thomas Manes of the Burton Group consultancy. Reports of typical errors and omissions would pile up. Gartner published a list even with SOA – deadly sins. Example IT costs: According to a study by Saugatuck technology 57 percent of the executives expect decreasing expenditure as a result of their SOA efforts although.
But hardly anything is hear of concrete savings in ongoing or completed projects. Given the high upfront costs, it seems rather the opposite to be the case\”, so the computer week. Example agility: SOA company, IT allow to make more flexible and to be agile, advertise the software provider. The problem behind this argument is complex. Budget managers can do is often the vague term; they require concrete targets and results.
