Development and Maintenance of Gap Solutions for Telecoms OSS/BSS
Customer: Cult Hill Innovations Limited
Industry: Telecommunication
Solution type: Operations Support Software
Technologies: Java, Swing, CORBA, SWT, XML, XSL, XSLT, MySQL

Cult Hill Innovations Limited (CHIL) provides business software solutions for network operators, communication service providers and dealers.
The challenge for Sigma Ukraine was to establish a remote software factory capable of delivering a ready-to-market innovative software product and then support the client`s projects and maintain product installations. Developed by Sigma Ukraine, the OSS software product has the ability to work in a distributed environment. The software product is aimed at giving business developers a comprehensive and easy-to-use tool to build and verify new business models and automatically generate the Operations Support Systems (OSS).

The main features of the product allow the customer to:

  • Transform the way service providers create and implement new business capabilities;
  • Give non-technical business users a visual tool to assemble new applications and test their business models;
  • Model and launch new services in a fraction of the time previously required;
  • Automatically generate operations support functions;
  • Provide a single framework for invoicing multiple services;
  • Take a strategic approach to existing and new processes.

Currently the software factory is in widespread use and continues to support further software evolutions, participates in further development and technical support of implemented product installations. Staffed and locally managed by Sigma Ukraine for five years now, the software factory has become an integral part of the UK software house's operations, providing an economic virtual extension of its IT organization. An application is used by major European telecom companies.
