Setting the Scene

Willis Towers Watson had the following challenges with its existing collaboration solution:


  • Expensive third-party conferencing solutions.
  • Employees weren’t using the existing video conferencing solutions.
  • Office space was not used efficiently due to dedicated and shared desks.
  • Flexible working was not possible.
Global Microsoft Collaboration

After Cisilion was chosen as the partner for Willis Towers Watson, significant investment was made in an on-premise Microsoft Collaboration environment.

The project started as a POC at the Willis Towers Watson London HQ. The further deployment will consist of three core regions AsiaPacific, EMEA, and the Americas, each with two sites.
