Practical Aspects of the Implementation of OSS Transformation


Published on

OSS transformation presents significant opportunities for CSPs. However, the complexity and investments involved in such projects obliges CSPs to consider an entire range of aspects.

This presentation highlights the benefits operators can achieve from OSS transformation, defines the building blocks of a practical transformation process and emphasizes the effect of the integrated NOC on customer satisfaction.

Practical Aspects of the Implementation of OSS Transformation

  1. 1. Practical Aspects ofthe Implementation ofOSS Transformation <br />Duby Yoely<br />Vice President, Marketing and Solution Engineering<br />
  2. 2. Agenda<br />Common Starting Point and Expectations<br />OSS Transformation (OSS.T) Plan<br />Practical Aspects of OSS.T<br /> Domain Consolidation<br /> Fault Resolution Framework<br /> Vertical Integration<br /> Cross domain Thresholding<br /> Integrate OSS and BSS<br />
  3. 3. Individual Solutions =Fragmented OSS<br />Information is fragmented, prone to errors and inaccuracies.<br />Manual data management by different departments and personnel.<br />Unable to support the anticipated exponential growth of data.<br />Architecture is not economically scalable.<br />
  4. 4. What We Expect to Attain? <br />Simplification of the complexity of merging legacy and Next Generation Networks.<br />Increase the accuracy and consistency of information and make it more accessible.<br />A reduction of operating and capital expenditure through efficiency.<br />Improved levels of customer service through improved quality assurance processes.<br />
  5. 5. Transformation = Survival<br />“If the environment about you is changing but you aren’t, you’re vulnerable to extinction; <br />and not only do you need to evolve to survive but to thrive in existing and future environments.”<br />Keith Willetts Chairman and CEO, TM Forum<br />
