viding software as a service and cloud computing will lead to new business opportunities and business innovations. Introduction The development of the OSS/BSS software market is considered from three complementary viewpoints: business process, technology, and software market. Process. Software is deployed to automate and improve the execution of business processes. In a competitive market situation, standard level business process sup- port is required to enter the market or retain a position in it. Advantage in competi- tion can be achieved through improvement in the processes, unique services or quality outperforming the competition. Therefore, the research started out with a look into the current situation of business processes and the currently available software offering for CSP processes by comparing the software offerings to the TM Forums enhanced Telecomm Operations Map (eTOM). Technology. Hardware technology innovation and evolution are complemented by developments in software. Hardware and software interfaces represent a crucial factor enabling new product and service development for new network technolo- gies. Proprietary interfaces keep the control of related developments in the hands of the developer, whereas opening the interfaces for common use opens up market segments for a variety of applications. Therefore, considering software implemen- tation in different phases of standardization, as well as considering the integration of systems using software developed by multiple companies are in the second focus area of the research project. Software Market. The software market and the recent developments in it are naturally the third focus area. The market data being analyzed includes both the data supplied by software companies in this market and the data from telecom operator companies buying their software. The analysis of the CSP business is elaborated both by interviews on their software procurement and by analysing CSP business process improvement. Some of the research questions addressed in the pr
