A recent report by Martina Kurth (pictured), Research Director, Gartner (curtsey of Oracle) "evaluates the capabilities of end-to-end vendors in the global market for OSS service assurance and fulfillment, a market characterized by simultaneous consolidation and vibrant innovation by startups".
"Overall, we expect the worldwide OSS market to grow from $25.3 billion in 2010 to $32.9 billion in 2015".
"Major OSS investment areas include order to fulfillment processes across logical inventory and adjacent product and service catalog domains, and policy management. On the other hand, we see a major revitalization around service quality management and the corresponding network performance and capacity planning, which often revolve around enterprisewide CEM initiatives, by adding an additional analytics and data correlation layer"
