Business/Technology Editors

READING and BRACKNELL, England--(BUSINESS WIRE)--March 6, 2000

Alliance combines eBusiness infrastructure and expertise from

CITL with proven integration products from Active Software

Active Software, Inc. (Nasdaq: ASWX), a leading provider of eBusiness infrastructure products, and CITL, an independent enterprise IT consultancy, today announced a partnership to deliver rapid eBusiness solutions to the UK business community. The combination of CITL's broad business and technical consulting expertise, and Active Software's ActiveWorks(TM) Integration System will enable customers to quickly transform into eBusinesses by providing a platform to share information within and across the extended enterprise.

CITL believes that established businesses can win competitive advantage over new "dot.com" companies by extending their brand strength, business process management and customer service expertise into eBusiness. However, for such established businesses to capitalise on these strengths, their e-commerce activities need to be integrated with existing operations such as sales, customer care, finance, order processing and fulfilment. These typically operate over a mixed set of incompatible legacy and distributed technologies and require integration. Working with integration products such as ActiveWorks, and using its own proven methodology for enterprise application integration (EAI), CITL can help businesses to integrate legacy and distributed technologies. It can help businesses to implement Web technologies and to launch eBusiness operations - rapidly and `right the first time.'

Ed Wrazen, CITL's EAI practice director said: "For the non-expert integrator, eBusiness integration is a risky undertaking. The pressure for speed over competitors, the complexity in understanding business processes and of the wide range of technologies involved places considerable demand on in-house staff. CITL's degree of exposure to large integration projects, its proven methodology and broad range of technical skills coupled with the power of ActiveWorks enable us to minimise risk and present a comprehensive eBusiness integration service."

Roy Murphy, vice president, Europe, Middle East and Africa, for Active Software, Inc. said: "ActiveWorks was developed as a fast way to solve eBusiness integration problems inside the enterprise and with B2B trading partners. CITL adds further eBusiness integration skill to ActiveWorks to enable UK customers to quickly transform into eBusinesses."

Commenting on the new partnership, Steve Craggs, industry analyst, Saint Consulting Limited, said: "Successful eBusiness solutions require both comprehensive products as well as skilled professionals who can define the business needs and configure the products. Partnerships such as this provide complementary products and services, enabling remarkably fast and successful deployment."
