This document fulfils the requirements for the final Thesis in completion of an Engineering Doctorate program at the University of Southampton. This Thesis presents the findings of a three and a half year Engineering Doctorate study (2003-2007) which investigated the options for open source in delivering Operational Support Systems (OSS) to the global telecommunications industry. The principal mode of investigation has been Action Research in collaboration with a number of industry players and in support of the New Generation Operations Support Systems (NGOSS) standardisation activities conducted under the auspices of the Telemanagement Forum ( The thesis considers the use of open source to expedite the creation and dissemination of emerging ass standards through a number of collaborative industrial projects including a Next Generation Network proof .' ofconcept and a novel application ofNGOSS to the problem ofmanaging a digital TV network. Conclusions are drawn as to the benefits which service providers could derive from using open source as a key factor in managing the strategic risks and costs associated with the new product introduction process. The principal contribution has been to develop within the telecommunications industry a greater understanding and acceptance ofthe role which open source can have in the delivery ofOSS solutions.
